Since Spring Framework 4.2, DefaultContextCache supported an LRU (least
recently used) eviction policy via a custom LruCache which extended
LinkedHashMap. The LruCache reacted to LinkedHashMap's
removeEldestEntry() callback to remove the LRU context if the maxSize
of the cache was exceeded.
Due to the nature of the implementation in LinkedHashMap, the
removeEldestEntry() callback is invoked after a new entry has been
stored to the map.
Consequently, a Spring ApplicationContext (C1) was evicted from the
cache after a new context (C2) was loaded and added to the cache,
leading to failure scenarios such as the following.
- C1 and C2 share an external resource -- for example, a database.
- C2 initializes the external resource with test data when C2 is loaded.
- C1 cleans up the external resource when C1 is closed.
- C1 is loaded and added to the cache.
- C2 is loaded and added to the cache before C1 is evicted.
- C1 is evicted and closed.
- C2 tests fail, because C1 removed test data required for C2.
To address such scenarios, this commit replaces the custom LruCache
with custom LRU eviction logic in DefaultContextCache and revises
the put(MergedContextConfiguration, ApplicationContext) method to
delegate to a new evictLruContextIfNecessary() method.
This commit also introduces a new put(MergedContextConfiguration,
LoadFunction) method in the ContextCache API which is overridden by
DefaultContextCache to ensure that an evicted context is removed and
closed before a new context is loaded to take its place in the cache.
In addition, DefaultCacheAwareContextLoaderDelegate has been revised to
make use of the new put(MergedContextConfiguration, LoadFunction) API.

This commit updates Jackson 3 JSON support to use JsonMapper
instead of ObjectMapper in converters, codecs and view constructors.
As a consequence, AbstractJacksonDecoder, AbstractJacksonEncoder,
AbstractJacksonHttpMessageConverter and JacksonCodecSupport are
now parameterized with <T extends ObjectMapper>.
Closes gh-35282
Since the introduction of the Spring TestContext Framework in 2007,
application contexts have always been stored in the context cache in a
"running" state. However, leaving a context running means that
components in the context may continue to run in the background. For
example, JMS listeners may continue to consume messages from a queue;
scheduled tasks may continue to perform active work, etc.; and this can
lead to issues within a test suite.
To address such issues, this commit introduces built-in support for
pausing application contexts when they are not in use and restarting
them if they are needed again.
Specifically, the TestContextManager now marks a test's application
context as "unused" after execution of the test class has ended, and
the underlying ContextCache then "stops" the application context if no
other test class is currently using the context. When a
TestExecutionListener later attempts to obtain a paused application
context -- for example, for a subsequent test class that shares the
same application context -- the ContextCache ensures that context is
restarted before returning it.

This allows autowiring a MockServerSpec in test class and using a different
identity or none at all with each test.

JUnit 5.13 introduced support for Discovery Issues which typically
indicate configuration errors in tests that may result in unexpected
behavior.
Furthermore, discovery issues that are currently reported at INFO level
may later be reported at WARNING or ERROR level -- for example, in
JUnit 6.
In order to ensure that our test suite does not suffer from such
potential errors, this commit sets the
junit.platform.discovery.issue.severity.critical JVM system property to
INFO (instead of leaving it with the default ERROR configuration).
Doing so aligns with our build configuration which fails the build for
selected warnings in Java source code and Javadoc.
If we later determine that INFO causes unnecessary issues for us, we
can switch to WARNING.
This commit also removes two "intentionally invalid" test cases from
AutowiredConfigurationErrorsIntegrationTests, since those test cases
are now reported as invalid as of JUnit 5.13.
Closes gh-35107
After further consideration, we have decided to remove the recently
introduced MockSslInfo in favor of introducing the following static
factory methods directly in the SslInfo interface.
- SslInfo.from(String sessionId)
- SslInfo from(String sessionId, X509Certificate... peerCertificates)
See gh-35042
See gh-35078
Prior to this commit, there was no easy way to configure an SslInfo
instance for use with WebTestClient.
To address that, this commit introduces a new sslInfo(SslInfo) method
in WebTestClient.MockServerSpec, which can be used as follows.
var client = WebTestClient.bindToApplicationContext(context)
.sslInfo(new MockSslInfo("mock ID"))
// ...
.build();
Closes gh-35042
Prior to this commit, the sslInfo() method in MockServerHttpRequest's
BaseBuilder returned void, which prevented it from being used with the
intended fluent Builder pattern.
This commit changes the return type to the builder (B) for proper method
chaining.
Closes gh-35075
Thanks to the new Discovery Issue Reporting mechanism introduced in JUnit 5.13, I became
aware of the fact that the @Order annotations in NestedAfterTestClassSqlScriptsTests
were being silently ignored.
To address that, this commit redeclares @TestMethodOrder on @Nested test class.
- Improve Javadoc.
- Suppress warnings for "removal".
- Update copyright headers.
- Migrate several tests from:
- MappingJackson2MessageConverter to JacksonJsonMessageConverter
- Jackson2JsonEncoder to JacksonJsonEncoder
- Jackson2JsonDecoder to JacksonJsonDecoder
- Jackson2SmileEncoder to JacksonSmileEncoder
- Jackson2ObjectMapperBuilder to JsonMapper and XmlMapper
- MappingJackson2JsonView to JacksonJsonView
- MappingJackson2HttpMessageConverter to JacksonJsonHttpMessageConverter
- MappingJackson2XmlHttpMessageConverter to JacksonXmlHttpMessageConverter
This commit introduces Jackson 3 based variants of the following
Jackson 2 classes (and related dependent classes).
MappingJackson2JsonView -> JacksonJsonView
MappingJackson2XmlView-> JacksonXmlView
