Prior to this commit the Spring TestContext Framework supported creating
only flat, non-hierarchical contexts. There was no easy way to create
contexts with parent-child relationships.
This commit addresses this issue by introducing a new @ContextHierarchy
annotation that can be used in conjunction with @ContextConfiguration
for declaring hierarchies of application contexts, either within a
single test class or within a test class hierarchy. In addition,
@DirtiesContext now supports a new 'hierarchyMode' attribute for
controlling context cache clearing for context hierarchies.
- Introduced a new @ContextHierarchy annotation.
- Introduced 'name' attribute in @ContextConfiguration.
- Introduced 'name' property in ContextConfigurationAttributes.
- TestContext is now aware of @ContextHierarchy in addition to
@ContextConfiguration.
- Introduced findAnnotationDeclaringClassForTypes() in AnnotationUtils.
- Introduced resolveContextHierarchyAttributes() in ContextLoaderUtils.
- Introduced buildContextHierarchyMap() in ContextLoaderUtils.
- @ContextConfiguration and @ContextHierarchy may not be used as
top-level, class-level annotations simultaneously.
- Introduced reference to the parent configuration in
MergedContextConfiguration and WebMergedContextConfiguration.
- Introduced overloaded buildMergedContextConfiguration() methods in
ContextLoaderUtils in order to handle context hierarchies separately
from conventional, non-hierarchical contexts.
- Introduced hashCode() and equals() in ContextConfigurationAttributes.
- ContextLoaderUtils ensures uniqueness of @ContextConfiguration
elements within a single @ContextHierarchy declaration.
- Introduced CacheAwareContextLoaderDelegate that can be used for
loading contexts with transparent support for interacting with the
context cache -- for example, for retrieving the parent application
context in a context hierarchy.
- TestContext now delegates to CacheAwareContextLoaderDelegate for
loading contexts.
- Introduced getParentApplicationContext() in MergedContextConfiguration
- The loadContext(MergedContextConfiguration) methods in
AbstractGenericContextLoader and AbstractGenericWebContextLoader now
set the parent context as appropriate.
- Introduced 'hierarchyMode' attribute in @DirtiesContext with a
corresponding HierarchyMode enum that defines EXHAUSTIVE and
CURRENT_LEVEL cache removal modes.
- ContextCache now internally tracks the relationships between contexts
that make up a context hierarchy. Furthermore, when a context is
removed, if it is part of a context hierarchy all corresponding
contexts will be removed from the cache according to the supplied
HierarchyMode.
- AbstractGenericWebContextLoader will set a loaded context as the
ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE in the MockServletContext when
context hierarchies are used if the context has no parent or if the
context has a parent that is not a WAC.
- Where appropriate, updated Javadoc to refer to the
ServletTestExecutionListener, which was introduced in 3.2.0.
- Updated Javadoc to avoid and/or suppress warnings in spring-test.
- Suppressed remaining warnings in code in spring-test.
Issue: SPR-5613, SPR-9863
Allow @Cachable, @CachePut and equivalent XML configuration to provide
a SpEL expression that can be used to veto putting an item into the
cache. Unlike 'condition' the 'unless' parameter is evaluated after
the method has been called and can therefore reference the #result.
For example:
@Cacheable(value="book",
condition="#name.length < 32",
unless="#result.hardback")
This commit also allows #result to be referenced from @CacheEvict
expressions as long as 'beforeInvocation' is false.
Issue: SPR-8871
This change upgrades the spring-framework build to AspectJ 1.7.1 to
ensure compatibility. We remain backward-compatible to at least AJ
1.6.12 (the previous version), and likely back to 1.6.7.
AJ 1.7 allows for weaving Java 7 bytecode, particularly with regard
to invokedynamic instructions, and furthermore makes improvements to
the aspectj language itself to allow users to take advantage of Java 7-
style language features within aspects. See [1] for details.
