Prior to this commit, the getValue(Annotation, String) method in
AnnotationUtils failed to retrieve the value of the desired annotation
attribute if the annotation itself was not public -- for example if the
annotation was declared as package private.
This commit addresses this issue by ensuring that getValue(Annotation,
String) uses reflection to make the desired annotation attribute method
accessible before attempting to invoke it to retrieve the value.

Since @Bean methods are never used with externally specified constructor argument values but rather just with autowiring, the non-lenient constructor resolution mode is appropriate in case of an overloaded @Bean method, not performing any type difference weight checks. This change includes a refinement of Spring's existing non-lenient constructor resolution (which needs to be explicitly turned on and is therefore not well tested), narrowing the conditions for the ambiguity check (only in case of the same number of arguments and not for overridden methods).
Issue: SPR-10988
Update MatchAlwaysTransactionAttributeSource.getTransactionAttribute
to allow a null method argument. Passing a null method is not
recommended and is not indicated as valid in the Javadoc, however,
this was allowed in previous versions of Spring.
Issue: SPR-11048
Update ResolvableType to check that the resolved component type from
a generic array is not null before attempting to use it to generate the
resolved array class.
Issue: SPR-11044
In particular, do not apply them to GroovyObject methods and other kinds of synthetic methods in language runtimes. The only exception are bridge methods since those do eventually point to a user-level generic method.
Issue: SPR-10803
Introduced a "setCachePatterns(boolean)" method for explicit configuration, a default turnoff threshold at 65536 entries (at which point we're deciding that caching isn't worthwhile because patterns are unlikely to be reoccurring often enough), and an "AntPathStringMatcher getStringMatcher(String pattern)" template method.

Spring 3.0 already allows component stereotypes to be used in a
meta-annotation fashion, for example by creating a custom
@TransactionalService stereotype annotation which combines
@Transactional and @Service in a single, reusable, application-specific
annotation. However, the Spring TestContext Framework (TCF) currently
does not provide any support for test-related annotations to be used as
meta-annotations.
This commit overhauls the TCF with regard to how annotations are
retrieved and adds explicit support for the following annotations to be
used as meta-annotations in conjunction with the TCF.
- @ContextConfiguration
- @ContextHierarchy
- @ActiveProfiles
- @DirtiesContext
- @IfProfileValue
- @ProfileValueSourceConfiguration
- @BeforeTransaction
- @AfterTransaction
- @TransactionConfiguration
- @Rollback
- @TestExecutionListeners
- @Repeat
- @Timed
- @WebAppConfiguration
Note that meta-annotation support for @Transactional was already
available prior to this commit.
The following is a summary of the major changes included in this commit.
- Now using AnnotationUtils.getAnnotation() instead of
Class.getAnnotation() where appropriate in the TestContext Framework.
- Now using AnnotationUtils.findAnnotation() instead of
Class.isAnnotationPresent() where appropriate in the TestContext
Framework.
- Introduced findAnnotationPrefersInteracesOverLocalMetaAnnotations() in
AnnotationUtilsTests in order to verify the status quo.
- AnnotationUtils.findAnnotationDeclaringClass() and
AnnotationUtils.findAnnotationDeclaringClassForTypes() now support
meta annotations.
- Introduced MetaAnnotationUtils and AnnotationDescriptor in the
spring-test module.
- Introduced UntypedAnnotationDescriptor in MetaAnnotationUtils.
- Introduced findAnnotationDescriptorForTypes() in MetaAnnotationUtils.
- ContextLoaderUtils now uses MetaAnnotationUtils for looking up
@ActiveProfiles as a potential meta-annotation.
- TestContextManager now uses MetaAnnotationUtils for looking up
@TestExecutionListeners as a potential meta-annotation.
- DirtiesContextTestExecutionListener now uses AnnotationUtils for
looking up @DirtiesContext as a potential meta-annotation.
- Introduced DirtiesContextTestExecutionListenerTests.
- ProfileValueUtils now uses AnnotationUtils for looking up
@IfProfileValue and @ProfileValueSourceConfiguration as potential
meta-annotations.
- @BeforeTransaction and @AfterTransaction now support ANNOTATION_TYPE
as a target, allowing them to be used as meta-annotations.
- TransactionalTestExecutionListener now uses AnnotationUtils for
looking up @BeforeTransaction, @AfterTransaction, @Rollback, and
@TransactionConfiguration as potential meta-annotations.
- Introduced TransactionalTestExecutionListenerTests.
- @Repeat and @Timed now support ANNOTATION_TYPE as a target, allowing
them to be used as meta-annotations.
- SpringJUnit4ClassRunner now uses AnnotationUtils for looking up
@Repeat and @Timed as potential meta-annotations.
- Moved all remaining logic for building the MergedContextConfiguration
from the DefaultTestContext constructor to
ContextLoaderUtils.buildMergedContextConfiguration().
- Verified meta-annotation support for @WebAppConfiguration and
@ContextConfiguration.
Issue: SPR-7827
Add getSource() method to ResolvableType and TypeDescriptor allowing
access to the underlying source field or method parameter when possible.
Primarily added to provide access to additional type information or
meta-data that alternative JVM languages may provide.
Issue: SPR-10887
DefaultListableBeanFactory performs a fallback check for autowire candidates now, which GenericTypeAwareAutowireCandidateResolver implements to accept raw type matches if the target class has unresolvable type variables. Full generic matches are still preferred; the BeanFactory will only start looking for fallback matches if the first pass led to an empty result.
Issue: SPR-10993
Issue: SPR-11004
Support repeatable @PropertySource annotations in Java 8 and add
@PropertySources container annotation for Java 6/7. Also add an
ignoreResourceNotFound attribute to @PropertySource allowing missing
property resources to be silently ignored.
This commit also introduces some generally useful methods to
AnnotationUtils for working with @Repeatable annotations.
Issue: SPR-8371
The key contract is MvcUrls. An instance is automatically created with
the Spring MVC namespace and the MVC Java config but can also be easily
created in any configuration.
Some example tests can be found in DefaultMvcUrlsTests.
Issue: SPR-10665, SPR-8826
MvcUriComponentsBuilder allows creating URIs that point to Spring MVC
controller methods annotated with @RequestMapping. It builds them by
exposing a mock method invocation API similar to Mockito, records the
method invocations and thus builds up the URI by inspecting the mapping
annotations and the parameters handed into the method invocations.
Introduced a new SPI UriComponentsContributor that should be implemented
by HandlerMethodArgumentResolvers that actually contribute path segments
or query parameters to a URI. While the newly introduced
MvcUriComponentsBuilder looks up those UriComponentsContributor instances
from the MVC configuration.
The MvcUriComponentsBuilderFactory (name to be discussed - MvcUris maybe?)
prevents the multiple lookups by keeping the UriComponentsBuilder
instances in an instance variable. So an instance of the factory could
be exposed as Spring bean or through a HandlerMethodArgumentResolver to
be injected into Controller methods.
Issue: SPR-10665, SPR-8826
Refactor TypeDescriptor to use ResolvableType in order to retain full
generic type information, in the process fixing MultiValueMap support
in MapToMapConverter.
Issue: SPR-9499
- Support for serialization
- Allow programmatic creation of an array from a given component type
- Allow programmatic creation with given generics
- Extract generics from Class types using Class.getTypeParameters()
- Move TypeVariableResolver to an inner class (and make method private)
- Refine 'resolve()' algorithm
Issue: SPR-10973
- Now avoiding NullPointerExceptions in GenericTypeResolver's
resolveReturnTypeForGenericMethod() in case the supplied ClassLoader
is null.
- AutowireUtils.resolveReturnTypeForFactoryMethod() now properly
asserts that the supplied ClassLoader is not null.
- Fixed copy-n-paste errors in Javadoc for
AutowireUtils.resolveReturnTypeForFactoryMethod().
Issue: SPR-10411
Includes revisions of MethodParameter and DependencyDescriptor (in particular towards a reference to the containing class). Also refines several ResolvableType method signatures.
Issue: SPR-9965
We're consistently resolving class names now, and the entire algorithm moved from GenericTypeResolver to the internal AutowireUtils helper in the bean factory package.
Issue: SPR-10411
Refactor AbstractMessageConverterMethodArgumentResolver and
BridgeMethodResolver to use ResolvableType in preference to deprecated
GenericTypeResolver calls.
Issue: SPR-10980
Add a new ResolvableType Class which encapsulates java.lang.reflect.Type,
providing access to supertypes, interfaces and generic parameters along
with the ability to ultimately resolve to a java.lang.Class.
ResolvableTypes may be obtained from fields, method parameters, method
returns, classes or directly from a java.lang.reflect.Type. Most methods
will themselves return ResolvableTypes, allowing easy navigation.
For example:
private HashMap<Integer, List<String>> myMap;
public void example() {
ResolvableType t = ResolvableType.forField(
getClass().getDeclaredField("myMap"));
t.getSuperType(); // AbstractMap<Integer, List<String>>;
t.asMap(); // Map<Integer, List<String>>
t.getGeneric(0).resolve(); // Integer
t.getGeneric(1).resolve(); // List
t.getGeneric(1); // List<String>
t.resolveGeneric(1, 0); // String
}
Issue: SPR-10973
A few noteworthy minor changes: LocaleContext.getLocale() may return null in special cases (not by default), which our own accessing classes are able to handle now. If there is a non-null TimeZone user setting, we're exposing it to all collaborating libraries, in particular to JSTL, Velocity and JasperReports. Our JSR-310 and Joda-Time support falls back to checking the general LocaleContext TimeZone now, adapting it to their time zone types, if no more specific setting has been provided. Our DefaultConversionService has TimeZone<->ZoneId converters registered. And finally, we're using a custom parseTimeZoneString method now that doesn't accept the TimeZone.getTimeZone(String) GMT fallback for an invalid time zone id anymore.
Issue: SPR-1528

- Added ListenableFuture, ListenableFutureCallback,
ListenableFutureCallbackRegistry, and ListenableFutureTask.
- Using ListenableFuture in AsyncRestOperations/AsyncRestTemplate.
- Added AsyncListenableTaskExecutor, implemented in
SimpleAsyncTaskExecutor.
- Added FutureAdapter and ListenableFutureAdapter.
