### MultiRelease Jar
|
||||
|
||||
The `org.springframework.build.multiReleaseJar` plugin configures the project with MultiRelease JAR support.
|
||||
It creates a new SourceSet and dedicated tasks for each Java variant considered.
|
||||
This can be configured with the DSL, by setting a list of Java variants to configure:
|
||||
|
||||
```groovy
|
||||
plugins {
|
||||
id 'org.springframework.build.multiReleaseJar'
|
||||
}
|
||||
|
||||
multiRelease {
|
||||
releaseVersions 21, 24
|
||||
}
|
||||
```
|
||||
|
||||
Note, Java classes will be compiled with the toolchain pre-configured by the project, assuming that its
|
||||
Java language version is equal or higher than all variants we consider. Each compilation task will only
|
||||
set the "-release" compilation option accordingly to produce the expected bytecode version.

By default, the `AnnotationBeanNameGenerator` is used. For Spring

if you supply a name via the annotation's `value` attribute that name will be used as

As of Spring Framework 6.1, the name of the annotation attribute that is used to specify
|

the bean name is no longer required to be `value`. Custom stereotype annotations can
|

declare an attribute with a different name (such as `name`) and annotate that attribute
|
||||
with `@AliasFor(annotation = Component.class, attribute = "value")`. See the source code

declaration of `ControllerAdvice#name()` for a concrete example.

[WARNING]

|
||||
As of Spring Framework 6.1, support for convention-based stereotype names is deprecated

[TIP]
|
||||
====
|
||||
If you run into naming conflicts due to multiple autodetected components having the same
|
||||
non-qualified class name (for example, classes with identical names but residing in
|
||||
different packages), you can configure a `BeanNameGenerator` that defaults to the
|
||||
fully-qualified class name for the generated bean name. The
|
||||
`FullyQualifiedAnnotationBeanNameGenerator` can be used for such purposes.
|
||||
|
||||
As of Spring Framework 7.0, if you encounter naming conflicts among `@Bean` methods in
|
||||
`@Configuration` classes, you can alternatively configure a
|
||||
`ConfigurationBeanNameGenerator` that generates unique bean names for `@Bean` methods.
|
||||
The `FullyQualifiedConfigurationBeanNameGenerator` can be used to generate
|
||||
fully-qualified default bean names for `@Bean` methods without an explicit `name`
|
||||
attribute — for example, `com.example.MyConfig.myBean` for an `@Bean` method named
|
||||
`myBean()` declared in `@Configuration` class `com.example.MyConfig`.
|
||||
|
||||
The `FullyQualifiedAnnotationBeanNameGenerator` and
|
||||
`FullyQualifiedConfigurationBeanNameGenerator` both reside in the
|
||||
`org.springframework.context.annotation` package.
|
||||
====
|
||||
|
||||
As a general rule, consider specifying the name with the annotation whenever other
|
||||
components may be making explicit references to it. On the other hand, the
|
||||
auto-generated names are adequate whenever the container is responsible for wiring.

|

=== Providing a Scope for Autodetected Components
|
||||
|
||||
As with Spring-managed components in general, the default and most common scope for
|
||||
autodetected components is `singleton`. However, sometimes you need a different scope
|
||||
that can be specified by the `@Scope` annotation. You can provide the name of the
|
||||
scope within the annotation, as the following example shows:
|
||||
|
||||

|
||||
// ...
|
||||
}
|
||||
----
|
||||
======
|
||||
|
||||
NOTE: `@Scope` annotations are only introspected on the concrete bean class (for annotated
|
||||
components) or the factory method (for `@Bean` methods). In contrast to XML bean
|
||||
definitions, there is no notion of bean definition inheritance, and inheritance
|
||||
hierarchies at the class level are irrelevant for metadata purposes.
|
||||
|
||||
For details on web-specific scopes such as "`request`" or "`session`" in a Spring context,
|
||||
see xref:core/beans/factory-scopes.adoc#beans-factory-scopes-other[Request, Session, Application, and WebSocket Scopes].
|
||||
As with the pre-built annotations for those scopes, you may also compose your own scoping
|
||||
annotations by using Spring's meta-annotation approach: for example, a custom annotation
|
||||
meta-annotated with `@Scope("prototype")`, possibly also declaring a custom scoped-proxy mode.
|
||||
|
||||
NOTE: To provide a custom strategy for scope resolution rather than relying on the
|
||||
annotation-based approach, you can implement the
|
||||
{spring-framework-api}/context/annotation/ScopeMetadataResolver.html[`ScopeMetadataResolver`]
|
||||
interface. Be sure to include a default no-arg constructor. Then you can provide the
|
||||
fully qualified class name when configuring the scanner, as the following example of both
|
||||
an annotation and a bean definition shows:

When using certain non-singleton scopes, it may be necessary to generate proxies for the
|
||||
scoped objects. The reasoning is described in
|
||||
xref:core/beans/factory-scopes.adoc#beans-factory-scopes-other-injection[Scoped Beans as Dependencies].
|
||||
For this purpose, a scoped-proxy attribute is available on the component-scan
|
||||
element. The three possible values are: `no`, `interfaces`, and `targetClass`. For example,
|
||||
the following configuration results in standard JDK dynamic proxies:

|

=== Providing Qualifier Metadata with Annotations
|
||||
|
||||
The `@Qualifier` annotation is discussed in
|
||||
xref:core/beans/annotation-config/autowired-qualifiers.adoc[Fine-tuning Annotation-based Autowiring with Qualifiers].
|
||||
The examples in that section demonstrate the use of the `@Qualifier` annotation and
|
||||
custom qualifier annotations to provide fine-grained control when you resolve autowire
|
||||
candidates. Because those examples were based on XML bean definitions, the qualifier
|
||||
metadata was provided on the candidate bean definitions by using the `qualifier` or `meta`
|
||||
child elements of the `bean` element in the XML. When relying upon classpath scanning for
|
||||
auto-detection of components, you can provide the qualifier metadata with type-level
|
||||
annotations on the candidate class. The following three examples demonstrate this
|
||||
technique:

If you do not want to rely on the default bean-naming strategy, you can provide a custom
|
||||
bean-naming strategy. First, implement the
|
||||
{spring-framework-api}/beans/factory/support/BeanNameGenerator.html[`BeanNameGenerator`]
|
||||
interface, and be sure to include a default no-arg constructor. Then, provide the fully
|
||||
qualified class name when configuring the scanner, as the following example annotation
|
||||
and bean definition show.
|
||||
|
||||
TIP: If you run into naming conflicts due to multiple autodetected components having the
|
||||
same non-qualified class name (i.e., classes with identical names but residing in
|
||||
different packages), you may need to configure a `BeanNameGenerator` that defaults to the
|
||||
fully qualified class name for the generated bean name. The
|
||||
`FullyQualifiedAnnotationBeanNameGenerator` located in package
|
||||
`org.springframework.context.annotation` can be used for such purposes.

As a general rule, consider specifying the name with the annotation whenever other

components may be making explicit references to it. On the other hand, the

auto-generated names are adequate whenever the container is responsible for wiring.

== Providing a Scope for Autodetected Components
|
||||
|
||||
As with Spring-managed components in general, the default and most common scope for
|
||||
autodetected components is `singleton`. However, sometimes you need a different scope
|
||||
that can be specified by the `@Scope` annotation. You can provide the name of the
|
||||
scope within the annotation, as the following example shows:

||||

||||

|
||||
// ...
|
||||
}
|
||||
----
|
||||
======
|
||||
|
||||
NOTE: `@Scope` annotations are only introspected on the concrete bean class (for annotated
|
||||
components) or the factory method (for `@Bean` methods). In contrast to XML bean
|
||||
definitions, there is no notion of bean definition inheritance, and inheritance
|
||||
hierarchies at the class level are irrelevant for metadata purposes.
|
||||
|
||||
For details on web-specific scopes such as "`request`" or "`session`" in a Spring context,
|
||||
see xref:core/beans/factory-scopes.adoc#beans-factory-scopes-other[Request, Session, Application, and WebSocket Scopes].
|
||||
As with the pre-built annotations for those scopes, you may also compose your own scoping
|
||||
annotations by using Spring's meta-annotation approach: for example, a custom annotation
|
||||
meta-annotated with `@Scope("prototype")`, possibly also declaring a custom scoped-proxy mode.
|
||||
|
||||
NOTE: To provide a custom strategy for scope resolution rather than relying on the
|
||||
annotation-based approach, you can implement the
|
||||
{spring-framework-api}/context/annotation/ScopeMetadataResolver.html[`ScopeMetadataResolver`]
|
||||
interface. Be sure to include a default no-arg constructor. Then you can provide the
|
||||
fully qualified class name when configuring the scanner, as the following example of both
|
||||

When using certain non-singleton scopes, it may be necessary to generate proxies for the
|
||||
scoped objects. The reasoning is described in
|
||||
xref:core/beans/factory-scopes.adoc#beans-factory-scopes-other-injection[Scoped Beans as Dependencies].
|
||||
For this purpose, a scoped-proxy attribute is available on the component-scan
|
||||
element. The three possible values are: `no`, `interfaces`, and `targetClass`. For example,
|
||||
the following configuration results in standard JDK dynamic proxies:

== Providing Qualifier Metadata with Annotations
|
||||
|
||||
The `@Qualifier` annotation is discussed in
|
||||
xref:core/beans/annotation-config/autowired-qualifiers.adoc[Fine-tuning Annotation-based Autowiring with Qualifiers].
|
||||
The examples in that section demonstrate the use of the `@Qualifier` annotation and
|
||||
custom qualifier annotations to provide fine-grained control when you resolve autowire
|
||||
candidates. Because those examples were based on XML bean definitions, the qualifier
|
||||
metadata was provided on the candidate bean definitions by using the `qualifier` or `meta`
|
||||
child elements of the `bean` element in the XML. When relying upon classpath scanning for
|
||||
auto-detection of components, you can provide the qualifier metadata with type-level
|
||||
annotations on the candidate class. The following three examples demonstrate this
|
||||
technique:

|
||||
=== Security Considerations
|
||||
|
||||
SpEL is a powerful expression language that can invoke constructors and methods, read and
|
||||
write properties and fields, and reference beans – all backed by reflection. Because of
|
||||
this power, evaluating a SpEL expression obtained from an untrusted source is inherently
|
||||
dangerous and should generally be avoided, since doing so can effectively grant that
|
||||
source the ability to execute arbitrary code within the application, regardless of which
|
||||
`EvaluationContext` implementation is used.
|
||||
|
||||
Throughout this section, a source of a SpEL expression is considered "trusted" only if it
|
||||
is a developer of the application or an administrator responsible for configuring or
|
||||
operating the application. Any other source of a SpEL expression must be treated as
|
||||
untrusted – for example, an expression supplied by an end user of the application or
|
||||
received from an external system.
|
||||
|
||||
[WARNING]
|
||||
====
|
||||
`StandardEvaluationContext` exposes the complete SpEL language and must *never* be used
|
||||
to evaluate an expression obtained from an untrusted source.
|
||||
====
|
||||
|
||||
Although `SimpleEvaluationContext` restricts the SpEL language to a subset of its
|
||||
features, that restriction is provided on a best-effort basis and does not guarantee that
|
||||
expression evaluation is safe. Since an expression can potentially invoke any property,
|
||||
method, or function reachable via the configured root object, property accessors, method
|
||||
resolvers, variables, and functions, care must be taken if you choose to evaluate
|
||||
expressions from an untrusted source. It is therefore the responsibility of the code that
|
||||
configures an `EvaluationContext` – for example, by supplying a root object or by
|
||||
registering property accessors, resolvers, variables, or functions – to ensure that none
|
||||
of the objects reachable via the context expose operations that would be dangerous if
|
||||
invoked by an expression from an untrusted source.
|
||||
|
||||
Furthermore, a property "getter" reachable from an expression is not necessarily a pure,
|
||||
side-effect-free read operation. A JavaBean-style accessor (such as `getName()` or
|
||||
`isActive()`) and a plain accessor method used to support data classes such as Java
|
||||
records and Kotlin data classes (such as `name()`) are indistinguishable from a method
|
||||
that performs an action and happens to return a value (that is, a method which is
|
||||
*accessor-shaped*). For example, the `public boolean delete()` method in `java.io.File`
|
||||
looks like a plain accessor method to SpEL. Specifically, neither
|
||||
`ReflectivePropertyAccessor` nor `DataBindingPropertyAccessor` can determine whether such
|
||||
a method is free of side effects. Moreover, restricting a `SimpleEvaluationContext` to
|
||||
read-only data binding governs only whether *assignment* to a property is permitted: it
|
||||
does not verify that reading a property is side-effect-free. When exposing a root object
|
||||
or other reachable object to an untrusted expression, you must ensure that none of its
|
||||
accessor-shaped methods perform an action that would be unsafe if triggered by that
|
||||
expression.
|
||||
|
||||
[NOTE]
|
||||
.What makes a method "accessor-shaped"?
|
||||
====
|
||||
A method is accessor-shaped if it is `public`, takes no arguments, and returns a value –
|
||||
the same shape that `ReflectivePropertyAccessor` and `DataBindingPropertyAccessor` look
|
||||
for when resolving a property "getter" by name. That shape says nothing about whether
|
||||
invoking the method is actually free of side effects. For example, the following methods
|
||||
are all accessor-shaped, but only some of them are safe to invoke as a property read.
|
||||
|
||||
Side-effect-free (safe to expose as properties):
|
||||
|
||||
* `getName()` and `isActive()`: conventional JavaBean-style accessors.
|
||||
* `name()` and `active()`: plain accessor methods used by data classes such as Java
|
||||
records and Kotlin data classes.
|
||||
|
||||
Side-effecting (unsafe to expose as properties, despite the identical shape):
|
||||
|
||||
* `java.io.File#delete()`: deletes the underlying file and returns whether the deletion
|
||||
succeeded.
|
||||
* `java.util.Queue#poll()`: removes and returns the head element, mutating the queue.
|
||||
* `java.util.concurrent.atomic.AtomicInteger#incrementAndGet()`: increments and returns
|
||||
a counter, mutating it.
|
||||
|
||||
If an untrusted expression can reference `someFile.delete`, `someQueue.poll`, or
|
||||
`someCounter.incrementAndGet` as a property, SpEL invokes the corresponding method just
|
||||
as readily as it would invoke a genuine getter.
|

[[expressions-evaluation-context-object-design]]
|
||||
=== Object Design
|
||||
|
||||
Similar to the design guidance for
|
||||
xref:web/webmvc/mvc-data-binding.adoc#mvc-data-binding-design[web data binding], you
|
||||
should carefully design any object that may be reached from a SpEL expression evaluated
|
||||
against untrusted input. This applies not only to the root object supplied to an
|
||||
`EvaluationContext` but also to every object that such an expression can navigate to from
|
||||
that root object – for example, an object returned by a property, a method, an index
|
||||
operation, a variable, or a function.
|
||||
|
||||
When exposing an object to expressions from an untrusted source, consider the following
|
||||
recommendations.
|
||||
|
||||
Use a dedicated type::
|
||||
Prefer a dedicated type, designed specifically to be evaluated against untrusted
|
||||
expressions, over passing an existing domain or infrastructure type "as is". A
|
||||
dedicated type lets you control exactly which properties and methods are reachable from
|
||||
an expression, rather than exposing the full surface area of a class such as a JPA
|
||||
entity, `java.io.File`, or a JDBC `Connection` – most of which were never designed with
|
||||
SpEL evaluation in mind.
|
||||
|
||||
Prefer immutability::
|
||||
An immutable type – for example, a Java record or a Kotlin data class exposing only
|
||||
`val` properties – rules out property writes and eliminates any concern that a "getter"
|
||||
might mutate state as a side effect, since there is no mutable state to affect.
|
||||
Immutability does not, on its own, rule out an accessor-shaped method with an external
|
||||
side effect (such as a network call or a file system operation), but it removes an
|
||||
entire class of risk.
|
||||
|
||||
Limit scope::
|
||||
Expose only the properties and methods that the expression is expected to use, and
|
||||
nothing more. Because a `PropertyAccessor` cannot restrict access to specific
|
||||
properties or methods on a per-expression basis, every accessor-shaped method reachable
|
||||
on an exposed object is reachable by any expression that can reach that object –
|
||||
regardless of which property or method the application intended the expression to use.
|
||||
|
||||
Audit accessor-shaped methods::
|
||||
Review every accessor-shaped method exposed by a type before making it reachable from
|
||||
an untrusted expression, keeping the <<expressions-evaluation-context-security,
|
||||
security considerations>> discussed above in mind. None of the reachable methods should
|
||||
perform an action that would be unsafe if triggered by that expression.

||||

These recommendations apply transitively. If the root object exposes a property or method
|
||||
that returns another object, and an untrusted expression can navigate to it (for example,
|
||||
`rootObject.child.grandchild`), the nested object is just as reachable as the root object
|
||||
itself and must meet the same design requirements. The same is true for an object reached
|
||||
via indexing (for example, `rootObject.items[0]` or `rootObject.items['key']`): whatever
|
||||
is returned by the index operation is just as reachable as any other nested object.

[[expressions-evaluation-context-lifecycle]]

=== Lifecycle and Reuse
|
||||
|
||||
For performance, the AST nodes that make up a parsed `Expression` may cache the specific
|
||||
`PropertyAccessor`, `IndexAccessor`, `MethodExecutor`, or `ConstructorExecutor` that
|
||||
satisfied a previous evaluation, so that later evaluations of the same node can avoid
|
||||
asking every registered accessor or resolver in turn. Understanding this caching behavior
|
||||
is essential to using `Expression` and `EvaluationContext` correctly, in addition to the
|
||||
<<expressions-evaluation-context-security,security considerations>> discussed previously.
|
||||
|
||||
A parsed `Expression` is designed to be created once and evaluated repeatedly, and doing
|
||||
so is both supported and encouraged. In particular:
|
||||
|
||||
* A parsed `Expression` may be evaluated against different root objects, and against
|
||||
different `EvaluationContext` instances of the *same type and with equivalent
|
||||
configuration* – for example, several `StandardEvaluationContext` instances each
|
||||
registering the same kind of custom `PropertyAccessor`. Changing the accessors or
|
||||
resolvers registered with a context between evaluations of the same expression is
|
||||
atypical and generally not advised, but is expected to work correctly: the registered
|
||||
state of the *current* context is what is consulted, not a snapshot taken during an
|
||||
earlier evaluation.
|
||||
* A parsed `Expression` must *not* be evaluated first against a context with one set of
|
||||
security implications and later against a context with different, typically more
|
||||
restrictive, security implications – for example, first against a
|
||||
`StandardEvaluationContext` and later against a `SimpleEvaluationContext`. Doing so is
|
||||
analogous to executing a database query on behalf of an administrator, caching the
|
||||
resulting administrator-privileged execution plan, and then reusing that cached plan for
|
||||
a lower-privileged user while expecting the lower-privileged user's restrictions to
|
||||
apply: cached state from the first, more permissive evaluation may be reused during the
|
||||
second, and the second context's restrictions cannot be reliably enforced as a result.
|
||||
If the same expression string must be evaluated under contexts with different security
|
||||
implications, parse it into *distinct* `Expression` instances, one per context.
|
||||
|
||||
[WARNING]
|
||||
====
|
||||
Reusing a single parsed `Expression` across `EvaluationContext` instances with different
|
||||
security implications is not a supported usage pattern and must be avoided, regardless of
|
||||
which `EvaluationContext` implementations are involved.

It is possible to configure the SpEL expression parser by using a parser configuration

object (`org.springframework.expression.spel.SpelParserConfiguration`). The configuration
|

object controls the behavior of some of the expression components. To create a
|
||||
`SpelParserConfiguration` instance, favor `SpelParserConfiguration.builder()` over the
|
||||
numerous constructors in `SpelParserConfiguration`, since the builder only requires

configuration of the properties that need to deviate from their sensible defaults --

or use `SpelParserConfiguration.withDefaults()` if none of those defaults need to be

For example, if you index into a collection and the element at the specified index is

`null`, SpEL can automatically create the element. This is useful when using expressions

specify an index that is greater than the current size of the collection, SpEL can

at the specified index, SpEL will try to create the element using the element type's

default constructor before setting the specified value. If the element type does not

The SpEL Elvis operator also treats an _empty_ String like a `null` object. Thus, the

original Java example is only close to emulating the semantics of the operator: it would

need to use `name != null && !name.isEmpty()` as the predicate to be compatible with the

As of Spring Framework 7.0, the SpEL Elvis operator supports `java.util.Optional` with

transparent unwrapping semantics.

For example, given the expression `A ?: B`, if `A` is `null` or an _empty_ `Optional`,

the expression evaluates to `B`. However, if `A` is a non-empty `Optional` the expression

`Optional` which correlates to `A.get()`.

== Null-safe Operations on `Optional`
|
||||
|
||||
As of Spring Framework 7.0, null-safe operations are supported on instances of
|
||||
`java.util.Optional` with transparent unwrapping semantics.
|
||||
|
||||
Specifically, when a null-safe operator is applied to an _empty_ `Optional`, it will be
|
||||
treated as if the `Optional` were `null`, and the subsequent operation will evaluate to
|
||||
`null`. However, if a null-safe operator is applied to a non-empty `Optional`, the
|
||||
subsequent operation will be applied to the object contained in the `Optional`, thereby
|
||||
effectively unwrapping the `Optional`.
|
||||
|
||||
For example, if `user` is of type `Optional<User>`, the expression `user?.name` will
|
||||
evaluate to `null` if `user` is either `null` or an _empty_ `Optional` and will otherwise
|
||||
evaluate to the `name` of the `user`, effectively `user.get().getName()` or
|
||||
`user.get().name` for property or field access, respectively.
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
Invocations of methods defined in the `Optional` API are still supported on an _empty_
|
||||
`Optional`. For example, if `name` is of type `Optional<String>`, the expression
|
||||
`name?.orElse('Unknown')` will evaluate to `"Unknown"` if `name` is an empty `Optional`
|
||||
and will otherwise evaluate to the `String` contained in the `Optional` if `name` is a
|
||||
non-empty `Optional`, effectively `name.get()`.
|
||||
====
|
||||
|
||||
// NOTE: ⁠ is the Unicode Character 'WORD JOINER', which prevents undesired line wraps.
|
||||
|
||||
Similarly, if `names` is of type `Optional<List<String>>`, the expression
|
||||
`names?.?⁠[#this.length > 5]` will evaluate to `null` if `names` is `null` or an _empty_
|
||||
`Optional` and will otherwise evaluate to a sequence containing the names whose lengths
|
||||
are greater than 5, effectively
|
||||
`names.get().stream().filter(s -> s.length() > 5).toList()`.
|
||||
|
||||
The same semantics apply to all of the null-safe operators mentioned previously in this

||||
chapter.

||||
provides the following annotations in the `org.springframework.lang` package to let you
|
||||
declare nullability of APIs and fields:
|
||||
|
||||
The primary goal of this null-safety arrangement is to prevent a `NullPointerException` from being thrown at
|
||||
runtime via build time checks and to use explicit nullability as a way to express the possible absence of value.
|
||||
It is useful in Java by leveraging nullability checkers such as https://github.com/uber/NullAway[NullAway] or IDEs
|
||||
supporting JSpecify annotations such as IntelliJ IDEA and Eclipse (the latter requiring manual configuration). In Kotlin,
|
||||
JSpecify annotations are automatically translated to {kotlin-docs}/null-safety.html[Kotlin's null safety].
|
||||
* {spring-framework-api}/lang/Nullable.html[`@Nullable`]: Annotation to indicate that a
|
||||
specific parameter, return value, or field can be `null`.
|
||||
* {spring-framework-api}/lang/NonNull.html[`@NonNull`]: Annotation to indicate that a specific
|
||||
parameter, return value, or field cannot be `null` (not needed on parameters, return values,
|
||||
and fields where `@NonNullApi` and `@NonNullFields` apply, respectively).
|
||||
* {spring-framework-api}/lang/NonNullApi.html[`@NonNullApi`]: Annotation at the package level
|
||||
that declares non-null as the default semantics for parameters and return values.
|
||||
* {spring-framework-api}/lang/NonNullFields.html[`@NonNullFields`]: Annotation at the package
|
||||
level that declares non-null as the default semantics for fields.
|
||||
|
||||
The {spring-framework-api}/core/Nullness.html[`Nullness` Spring API] can be used at runtime to detect the
|
||||
nullness of a type usage, a field, a method return type, or a parameter. It provides full support for
|
||||
JSpecify annotations, Kotlin null safety, and Java primitive types, as well as a pragmatic check on any
|
||||
`@Nullable` annotation (regardless of the package).
|
||||
The Spring Framework itself leverages these annotations, but they can also be used in any
|
||||
Spring-based Java project to declare null-safe APIs and optionally null-safe fields.
|
||||
Nullability declarations for generic type arguments, varargs, and array elements are not supported yet.
|
||||
Nullability declarations are expected to be fine-tuned between Spring Framework releases,
|
||||
including minor ones. Nullability of types used inside method bodies is outside the
|
||||
scope of this feature.
|
||||
|
||||
NOTE: Other common libraries such as Reactor and Spring Data provide null-safe APIs that
|
||||
use a similar nullability arrangement, delivering a consistent overall experience for
|
||||
Spring application developers.

[[use-cases]]
|
||||
== Use cases
|
||||
|
||||
As of Spring Framework 7, the Spring Framework codebase leverages JSpecify annotations to expose null-safe APIs
|
||||
and to check the consistency of those nullability declarations with https://github.com/uber/NullAway[NullAway]
|
||||
as part of its build. It is recommended for each library depending on Spring Framework and Spring portfolio projects,
|
||||
as well as other libraries related to the Spring ecosystem (Reactor, Micrometer, and Spring community projects),
|
||||
to do the same.
|
||||
In addition to providing an explicit declaration for Spring Framework API nullability,
|
||||
these annotations can be used by an IDE (such as IDEA or Eclipse) to provide useful
|
||||
warnings related to null-safety in order to avoid `NullPointerException` at runtime.
|
||||
|
||||
They are also used to make Spring APIs null-safe in Kotlin projects, since Kotlin natively
|
||||
supports {kotlin-docs}/null-safety.html[null-safety]. More details
|
||||
are available in the xref:languages/kotlin/null-safety.adoc[Kotlin support documentation].

== Leveraging JSpecify annotations in Spring applications
|
||||
[[jsr-305-meta-annotations]]
|
||||
== JSR-305 meta-annotations
|
||||
|
||||
Developing applications with IDEs that support nullness annotations will provide warnings in Java and errors in
|
||||
Kotlin when the nullability contracts are not honored, allowing Spring application developers to refine their
|
||||
null handling to prevent a `NullPointerException` from being thrown at runtime.
|
||||
Spring annotations are meta-annotated with {JSR}305[JSR 305]
|
||||
annotations (a dormant but widespread JSR). JSR-305 meta-annotations let tooling vendors
|
||||
like IDEA or Kotlin provide null-safety support in a generic way, without having to
|
||||
hard-code support for Spring annotations.
|
||||
|
||||
Optionally, Spring application developers can annotate their codebase and use build plugins like
|
||||
https://github.com/uber/NullAway[NullAway] to enforce null-safety at the application level during build time.
|
||||
|
||||
[[null-safety-guidelines]]
|
||||
== Guidelines
|
||||
|
||||
The purpose of this section is to share some proposed guidelines for explicitly specifying the nullability of
|
||||
Spring-related libraries or applications.
|
||||
|
||||
[[null-safety-guidelines-jspecify]]
|
||||
=== JSpecify
|
||||
|
||||
==== Defaults to non-null
|
||||
|
||||
A key point to understand is that the nullness of types is unknown by default in Java and that non-null type usage
|
||||
is by far more frequent than nullable usage. In order to keep codebases readable, we typically want to define by
|
||||
default that type usage is non-null unless marked as nullable for a specific scope. This is exactly the purpose
|
||||
of https://jspecify.dev/docs/api/org/jspecify/annotations/NullMarked.html[`@NullMarked`] which is typically set
|
||||
in Spring projects at the package level via a `package-info.java` file, for example:
|
||||
|
||||
[source,java,subs="verbatim,quotes",chomp="-packages",fold="none"]
|
||||
----
|
||||
@NullMarked
|
||||
package org.springframework.core;
|
||||
|
||||
import org.jspecify.annotations.NullMarked;
|
||||
----
|
||||
|
||||
==== Explicit nullability
|
||||
|
||||
In `@NullMarked` code, nullable type usage is defined explicitly with
|
||||
https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html[`@Nullable`].
|
||||
|
||||
A key difference between JSpecify `@Nullable` / `@NonNull` annotations and most other variants is that the JSpecify
|
||||
annotations are meta-annotated with `@Target(ElementType.TYPE_USE)`, so they apply only to type usage. This impacts
|
||||
where such annotations should be placed, either to comply with
|
||||
https://docs.oracle.com/javase/specs/jls/se17/html/jls-9.html#jls-9.7.4[related Java specifications] or to follow code
|
||||
style best practices. From a style perspective, it is recommended to embrace the type-use nature of those annotations
|
||||
by placing them on the same line as and immediately preceding the annotated type.
|
||||
|
||||
For example, for a field:
|
||||
|
||||
[source,java,subs="verbatim,quotes"]
|
||||
----
|
||||
private @Nullable String fileEncoding;
|
||||
----
|
||||
|
||||
Or for method parameters and method return types:
|
||||
|
||||
[source,java,subs="verbatim,quotes"]
|
||||
----
|
||||
public @Nullable String buildMessage(@Nullable String message,
|
||||
@Nullable Throwable cause) {
|
||||
// ...
|
||||
}
|
||||
----
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
When overriding a method, JSpecify annotations are not inherited from the original
|
||||
method. That means the JSpecify annotations should be copied to the overriding method if
|
||||
you want to override the implementation and keep the same nullability semantics.
|
||||
====
|
||||
|
||||
https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html[`@NonNull`] and
|
||||
https://jspecify.dev/docs/api/org/jspecify/annotations/NullUnmarked.html[`@NullUnmarked`] should rarely be needed for
|
||||
typical use cases.
|
||||
|
||||
==== Arrays and varargs
|
||||
|
||||
With arrays and varargs, you need to be able to differentiate the nullness of the elements from the nullness of
|
||||
the array itself. Pay attention to the syntax
|
||||
https://docs.oracle.com/javase/specs/jls/se17/html/jls-9.html#jls-9.7.4[defined by the Java specification] which may be
|
||||
initially surprising. For example, in `@NullMarked` code:
|
||||
|
||||
- `@Nullable Object[] array` means individual elements can be `null` but the array itself cannot.
|
||||
- `Object @Nullable [] array` means individual elements cannot be `null` but the array itself can.
|
||||
- `@Nullable Object @Nullable [] array` means both individual elements and the array can be `null`.
|
||||
|
||||
==== Generics
|
||||
|
||||
JSpecify annotations apply to generics as well. For example, in `@NullMarked` code:
|
||||
|
||||
- `List<String>` means a list of non-null elements (equivalent of `List<@NonNull String>`)
|
||||
- `List<@Nullable String>` means a list of nullable elements
|
||||
|
||||
Things are a bit more complicated when you are declaring generic types or generic methods. See the related
|
||||
https://jspecify.dev/docs/user-guide/#generics[JSpecify generics documentation] for more details.
|
||||
|
||||
WARNING: The nullability of generic types and generic methods
|
||||
https://github.com/uber/NullAway/issues?q=is%3Aissue+is%3Aopen+label%3Ajspecify[is not yet fully supported by NullAway].
|
||||
|
||||
==== Nested and fully qualified types
|
||||
|
||||
The Java specification also enforces that annotations defined with `@Target(ElementType.TYPE_USE)` – like JSpecify's
|
||||
`@Nullable` annotation – must be declared after the last dot (`.`) within inner or fully qualified type names:
|
||||
|
||||
- `Cache.@Nullable ValueWrapper`
|
||||
- `jakarta.validation.@Nullable Validator`
|
||||
|
||||
|
||||
[[null-safety-guidelines-nullaway]]
|
||||
=== NullAway
|
||||
|
||||
==== Configuration
|
||||
|
||||
The recommended configuration is:
|
||||
|
||||
- `NullAway:OnlyNullMarked=true` in order to perform nullability checks only for packages annotated with `@NullMarked`.
|
||||
- `NullAway:CustomContractAnnotations=org.springframework.lang.Contract` which makes NullAway aware of the
|
||||
{spring-framework-api}/lang/Contract.html[@Contract] annotation in the `org.springframework.lang` package which
|
||||
can be used to express complementary semantics to avoid irrelevant warnings in your codebase.
|
||||
|
||||
A good example of the benefits of a `@Contract` declaration can be seen with
|
||||
{spring-framework-api}/util/Assert.html#notNull(java.lang.Object,java.lang.String)[`Assert.notNull()`]
|
||||
which is annotated with `@Contract("null, _ -> fail")`. With that contract declaration, NullAway will understand
|
||||
that the value passed as a parameter cannot be null after a successful invocation of `Assert.notNull()`.
|
||||
|
||||
Optionally, it is possible to set `NullAway:JSpecifyMode=true` to enable
|
||||
https://github.com/uber/NullAway/wiki/JSpecify-Support[checks on the full JSpecify semantics], including annotations on
|
||||
arrays, varargs, and generics. Be aware that this mode is
|
||||
https://github.com/uber/NullAway/issues?q=is%3Aissue+is%3Aopen+label%3Ajspecify[still under development] and requires
|
||||
JDK 22 or later (typically combined with the `--release` Java compiler flag to configure the
|
||||
expected baseline). It is recommended to enable the JSpecify mode only as a second step, after making sure the codebase
|
||||
generates no warning with the recommended configuration mentioned previously in this section.
|
||||
|
||||
==== Warnings suppression
|
||||
|
||||
There are a few valid use cases where NullAway will incorrectly detect nullability problems. In such cases,
|
||||
it is recommended to suppress related warnings and to document the reason:
|
||||
|
||||
- `@SuppressWarnings("NullAway.Init")` at field, constructor, or class level can be used to avoid unnecessary warnings
|
||||
due to the lazy initialization of fields – for example, due to a class implementing
|
||||
{spring-framework-api}/beans/factory/InitializingBean.html[`InitializingBean`].
|
||||
- `@SuppressWarnings("NullAway") // Dataflow analysis limitation` can be used when NullAway dataflow analysis is not
|
||||
able to detect that the path involving a nullability problem will never happen.
|
||||
- `@SuppressWarnings("NullAway") // Lambda` can be used when NullAway does not take into account assertions performed
|
||||
outside of a lambda for the code path within the lambda.
|
||||
- `@SuppressWarnings("NullAway") // Reflection` can be used for some reflection operations that are known to return
|
||||
non-null values even if that cannot be expressed by the API.
|
||||
- `@SuppressWarnings("NullAway") // Well-known map keys` can be used when `Map#get` invocations are performed with keys
|
||||
that are known to be present and when non-null related values have been inserted previously.
|
||||
- `@SuppressWarnings("NullAway") // Overridden method does not define nullability` can be used when the superclass does
|
||||
not define nullability (typically when the superclass comes from an external dependency).
|
||||
- `@SuppressWarnings("NullAway") // See https://github.com/uber/NullAway/issues/1075` can be used when NullAway is not able to detect type variable nullness in generic methods.

[[null-safety-migrating]]
|
||||
== Migrating from Spring null-safety annotations
|
||||
|
||||
Spring null-safety annotations {spring-framework-api}/lang/Nullable.html[`@Nullable`],
|
||||
{spring-framework-api}/lang/NonNull.html[`@NonNull`],
|
||||
{spring-framework-api}/lang/NonNullApi.html[`@NonNullApi`], and
|
||||
{spring-framework-api}/lang/NonNullFields.html[`@NonNullFields`] in the `org.springframework.lang` package were
|
||||
introduced in Spring Framework 5 when JSpecify did not exist, and the best option at that time was to leverage
|
||||
meta-annotations from JSR 305 (a dormant but widespread JSR). They are deprecated as of Spring Framework 7 in favor of
|
||||
https://jspecify.dev/docs/start-here/[JSpecify] annotations, which provide significant enhancements such as properly
|
||||
defined specifications, a canonical dependency with no split-package issues, better tooling, better Kotlin integration,
|
||||
and the capability to specify nullability more precisely for more use cases.
|
||||
|
||||
A key difference is that Spring's deprecated null-safety annotations, which follow JSR 305 semantics, apply to fields,
|
||||
parameters, and return values; while JSpecify annotations apply to type usage. This subtle difference
|
||||
is pretty significant in practice, since it allows developers to differentiate between the nullness of elements and the
|
||||
nullness of arrays/varargs as well as to define the nullness of generic types.
|
||||
|
||||
That means array and varargs null-safety declarations have to be updated to keep the same semantics. For example
|
||||
`@Nullable Object[] array` with Spring annotations needs to be changed to `Object @Nullable [] array` with JSpecify
|
||||
annotations. The same applies to varargs.
|
||||
|
||||
It is also recommended to move field and return value annotations closer to the type and on the same line, for example:
|
||||
|
||||
- For fields, instead of `@Nullable private String field` with Spring annotations, use `private @Nullable String field`
|
||||
with JSpecify annotations.
|
||||
- For method return types, instead of `@Nullable public String method()` with Spring annotations, use
|
||||
`public @Nullable String method()` with JSpecify annotations.
|
||||
|
||||
Also, with JSpecify, you do not need to specify `@NonNull` when overriding a type usage annotated with `@Nullable`
|
||||
in the super method to "undo" the nullable declaration in null-marked code. Just declare it unannotated, and the
|
||||
null-marked defaults will apply (type usage is considered non-null unless explicitly annotated as nullable).
|
||||
It is neither necessary nor recommended to add a JSR-305 dependency to the project classpath to
|
||||
take advantage of Spring's null-safe APIs. Only projects such as Spring-based libraries that use
|
||||
null-safety annotations in their codebase should add `com.google.code.findbugs:jsr305:3.0.2`
|
||||
with `compileOnly` Gradle configuration or Maven `provided` scope to avoid compiler warnings.

As of 7.0, the core Spring Framework includes common resilience features, in particular

<<resilience-annotations-retryable>> and <<resilience-annotations-concurrencylimit>>
|

annotations for method invocations as well as <<resilience-programmatic-retry,

[[resilience-annotations-retryable]]
|
||||
== `@Retryable`
|
||||
|
||||
{spring-framework-api}/resilience/annotation/Retryable.html[`@Retryable`] is an annotation
|
||||
that specifies retry characteristics for an individual method (with the annotation
|
||||
declared at the method level), or for all proxy-invoked methods in a given class hierarchy
|
||||
(with the annotation declared at the type level).

----
|
||||
|
||||
By default, the method invocation will be retried for any exception thrown: with at most
|
||||
3 retry attempts (`maxRetries = 3`) after an initial failure, and a delay of 1 second
|
||||
between attempts. If all attempts have failed and the retry policy has been exhausted,
|
||||
the last original exception from the target method will be propagated to the caller.
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
A `@Retryable` method will be invoked at least once and retried at most `maxRetries`
|
||||
times, where `maxRetries` is the maximum number of retry attempts. Specifically,
|
||||
`total attempts = 1 initial attempt + maxRetries attempts`.
|
||||
|
||||
For example, if `maxRetries` is set to `4`, the `@Retryable` method will be invoked at
|
||||
least once and at most 5 times.
|
||||
====
|
||||
|
||||
This can be specifically adapted for every method if necessary — for example, by narrowing
|
||||
the exceptions to retry via the `includes` and `excludes` attributes. The supplied
|
||||
exception types will be matched against an exception thrown by a failed invocation as well
|
||||
as nested causes.

`@Retryable(includes{nbsp}={nbsp}MessageDeliveryException.class)`.
|
||||
|
||||
[TIP]
|
||||
====
|
||||
For advanced use cases, you can specify a custom `MethodRetryPredicate` via the
|
||||
`predicate` attribute in `@Retryable`, and the predicate will be used to determine whether
|
||||
to retry a failed method invocation based on a `Method` and a given `Throwable` – for
|
||||
example, by checking the message of the `Throwable`.
|
||||
|
||||
Custom predicates can be combined with `includes` and `excludes`; however, custom
|
||||
predicates will always be applied after `includes` and `excludes` have been applied.

----
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
When `delay` is `0` combined with a positive `jitter`, the delay never grows
|
||||
regardless of any configured `multiplier`, so the full configured `jitter` is
|
||||
applied directly as a random delay in the range from `0` to `min(jitter, maxDelay)`.

placeholder and SpEL support, as an alternative to the specifically typed annotation
|
||||
attributes used in the above examples.
|
||||
|
||||
[TIP]
|
||||
====
|
||||
During `@Retryable` processing, Spring publishes a `MethodRetryEvent` for every exception
|
||||
coming out of the target method. This can be used to track/log all original exceptions
|
||||
whereas the caller of the `@Retryable` method will only ever see the last exception.

[[resilience-annotations-concurrencylimit]]
|
||||
== `@ConcurrencyLimit`
|

|

{spring-framework-api}/resilience/annotation/ConcurrencyLimit.html[`@ConcurrencyLimit`] is
|
||||
an annotation that specifies a concurrency limit for an individual method (with the
|
||||
annotation declared at the method level), or for all proxy-invoked methods in a given
|
||||
class hierarchy (with the annotation declared at the type level).

|
||||

|
||||
}
|
||||
----
|
||||
|
||||
This is meant to protect the target resource from being accessed from too many threads at
|
||||
the same time, similar to the effect of a pool size limit for a thread pool or a
|
||||
connection pool that blocks access if its limit is reached.
|
||||
|
||||
You may optionally set the limit to `1`, effectively locking access to the target bean
|
||||
instance:
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|
||||
@ConcurrencyLimit(1)
|
||||
public void sendNotification() {
|
||||
this.jmsClient.destination("notifications").send(...);
|
||||
}
|
||||
----
|
||||
|
||||
Such limiting is particularly useful with Virtual Threads where there is generally no
|
||||
thread pool limit in place. For asynchronous tasks, this can be constrained on
|
||||
{spring-framework-api}/core/task/SimpleAsyncTaskExecutor.html[`SimpleAsyncTaskExecutor`].
|
||||
For synchronous invocations, this annotation provides equivalent behavior through
|
||||
{spring-framework-api}/aop/interceptor/ConcurrencyThrottleInterceptor.html[`ConcurrencyThrottleInterceptor`]
|
||||
which has been available since Spring Framework 1.0 for programmatic use with the AOP
|
||||
framework.
|
||||
|
||||
TIP: `@ConcurrencyLimit` also has a `limitString` attribute that provides property
|
||||
placeholder and SpEL support, as an alternative to the `int` based examples above.
|
||||

== Enabling Resilient Methods
|
||||
|
||||
Like many of Spring's core annotation-based features, `@Retryable` and `@ConcurrencyLimit`
|
||||
are designed as metadata that you can choose to honor or ignore. The most convenient way
|
||||
to enable processing of the resilience annotations is to declare
|
||||
{spring-framework-api}/resilience/annotation/EnableResilientMethods.html[`@EnableResilientMethods`]
|
||||
on a corresponding `@Configuration` class.
|
||||
|
||||
Alternatively, these annotations can be individually enabled by defining a
|
||||
`RetryAnnotationBeanPostProcessor` or a `ConcurrencyLimitBeanPostProcessor` bean in the
|
||||
context.

||||

||||

[[resilience-programmatic-retry]]
|
||||
== Programmatic Retry Support
|
||||
|
||||
In contrast to <<resilience-annotations-retryable>> which provides a declarative approach
|
||||
for specifying retry semantics for methods within beans registered in the
|
||||
`ApplicationContext`,
|
||||
{spring-framework-api}/core/retry/RetryTemplate.html[`RetryTemplate`] provides a
|
||||
programmatic API for retrying arbitrary blocks of code.
|
||||
|
||||
Specifically, a `RetryTemplate` executes and potentially retries a
|
||||
{spring-framework-api}/core/retry/Retryable.html[`Retryable`] operation based on a
|
||||
configured {spring-framework-api}/core/retry/RetryPolicy.html[`RetryPolicy`].
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|
||||
var retryTemplate = new RetryTemplate(); // <1>
|
||||
|
||||
retryTemplate.invoke(
|
||||
() -> jmsClient.destination("notifications").send(...));
|
||||
----
|
||||
<1> Implicitly uses `RetryPolicy.withDefaults()`.
|
||||
|
||||
By default, a retryable operation will be retried for any exception thrown: with at most
|
||||
3 retry attempts (`maxRetries = 3`) after an initial failure, and a delay of 1 second
|
||||
between attempts.
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
A retryable operation will be executed at least once and retried at most `maxRetries`
|
||||
times, where `maxRetries` is the maximum number of retry attempts. Specifically,
|
||||
`total attempts = 1 initial attempt + maxRetries attempts`.
|
||||
|
||||
For example, if `maxRetries` is set to `4`, the retryable operation will be invoked at
|
||||
least once and at most 5 times.
|
||||
====
|
||||
|
||||
If you only need to customize the number of retry attempts, you can use the
|
||||
`RetryPolicy.withMaxRetries()` factory method as demonstrated below.
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|
||||
var retryTemplate = new RetryTemplate(RetryPolicy.withMaxRetries(4)); // <1>
|
||||
|
||||
retryTemplate.invoke(
|
||||
() -> jmsClient.destination("notifications").send(...));
|
||||
----
|
||||
<1> Explicitly uses `RetryPolicy.withMaxRetries(4)`.
|
||||
|
||||
If you need to narrow the types of exceptions to retry, that can be achieved via the
|
||||
`includes()` and `excludes()` builder methods. The supplied exception types will be
|
||||
matched against an exception thrown by a failed operation as well as nested causes.
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|
||||
var retryPolicy = RetryPolicy.builder()
|
||||
.includes(MessageDeliveryException.class) // <1>
|
||||
.excludes(...) // <2>
|
||||
.build();
|
||||
|
||||
var retryTemplate = new RetryTemplate(retryPolicy);
|
||||
|
||||
retryTemplate.invoke(
|
||||
() -> jmsClient.destination("notifications").send(...));
|
||||
----
|
||||
<1> Specify one or more exception types to include.
|
||||
<2> Specify one or more exception types to exclude.
|
||||
|
||||
[TIP]
|
||||
====
|
||||
For advanced use cases, you can specify a custom `Predicate<Throwable>` via the
|
||||
`predicate()` method in the `RetryPolicy.Builder`, and the predicate will be used to
|
||||
determine whether to retry a failed operation based on a given `Throwable` – for example,
|
||||
by checking the message of the `Throwable`.
|
||||
|
||||
Custom predicates can be combined with `includes` and `excludes`; however, custom
|
||||
predicates will always be applied after `includes` and `excludes` have been applied.
|
||||
====
|
||||
|
||||
The following example demonstrates how to configure a `RetryPolicy` with 4 retry attempts
|
||||
and an exponential back-off strategy with a bit of jitter.
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|
||||
var retryPolicy = RetryPolicy.builder()
|
||||
.includes(MessageDeliveryException.class)
|
||||
.maxRetries(4)
|
||||
.delay(Duration.ofMillis(100))
|
||||
.jitter(Duration.ofMillis(10))
|
||||
.multiplier(2)
|
||||
.maxDelay(Duration.ofSeconds(1))
|
||||
.build();
|
||||
|
||||
var retryTemplate = new RetryTemplate(retryPolicy);
|
||||
|
||||
retryTemplate.invoke(
|
||||
() -> jmsClient.destination("notifications").send(...));
|
||||
----
|
||||
|
||||
[NOTE]
|
||||
====
|
||||
When `delay` is zero combined with a positive `jitter`, the delay never grows
|
||||
regardless of any configured `multiplier`, so the full configured `jitter` is
|
||||
applied directly as a random delay in the range from zero to `min(jitter, maxDelay)`.
|
||||
====
|
||||
|
||||
[TIP]
|
||||
====
|
||||
Although the factory methods and builder API for `RetryPolicy` cover most common
|
||||
configuration scenarios, you can implement a custom `RetryPolicy` for complete control
|
||||
over the types of exceptions that should trigger a retry as well as the
|
||||
{spring-framework-api}/util/backoff/BackOff.html[`BackOff`] strategy to use. Note that
|
||||
you can also configure a customized `BackOff` strategy via the `backOff()` method in
|
||||
the `RetryPolicy.Builder`.
|
||||
====
|
||||
|
||||
Note that the examples above apply a pattern similar to `@Retryable` method invocations
|
||||
where the last original exception will be propagated to the caller, using the `invoke`
|
||||
variants on `RetryTemplate` which are available with and without a return value.
|
||||
The callback may throw unchecked exceptions, the last one of which is exposed for
|
||||
direct handling on the caller side:
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]

|

}

catch (MessageDeliveryException ex) {
|

// coming out of the original JmsClient send method

});
|
||||
}
|
||||
catch (MessageDeliveryException ex) {
|
||||
// coming out of the original JmsClient send method
|
||||
}
|
||||
----
|
||||
|
||||
`RetryTemplate` instances are very light and can be created on the fly,
|
||||
potentially with a specific retry policy to use for a given invocation:
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|

try {

|
||||
}
|
||||
catch (MessageDeliveryException ex) {
|
||||
// coming out of the original JmsClient send method
|
||||
}
|
||||
----
|
||||
|
||||
For deeper interaction, you may use RetryTemplate's `execute` method. The caller will
|
||||
have to handle the checked `RetryException` thrown by `RetryTemplate`, exposing the
|
||||
outcome of all attempts:
|
||||
|
||||
[source,java,indent=0,subs="verbatim,quotes"]
|
||||
----
|

try {
|

var result = retryTemplate.execute(() -> {

----
|

|

A {spring-framework-api}/core/retry/RetryListener.html[`RetryListener`] can be registered
|
||||
with a `RetryTemplate` to react to key retry steps (before or after a retry attempt etc.)
|
||||
or simply to every invocation attempt, being able to track all exceptions coming out of
|
||||
the callback and all retry outcomes (exhaustion, interruption, timeout). This is
|
||||
particularly useful when using `invoke` where no retry state other than the last
|
||||
original exception is exposed otherwise:

Spring comes with its own Commons Logging bridge implemented
|

in the `spring-jcl` module. The implementation checks for the presence of the Log4j 2.x
|
||||
API and the SLF4J 1.7 API in the classpath and uses the first one of those found as the
|
||||
logging implementation, falling back to the Java platform's core logging facilities (also
|
||||
known as _JUL_ or `java.util.logging`) if neither Log4j 2.x nor SLF4J is available.
|
||||
|
||||
Put Log4j 2.x or Logback (or another SLF4J provider) in your classpath, without any extra
|

bridges, and let the framework auto-adapt to your choice. For further information see the
