In addition to specifying the event type to listen to via a method
parameter, any @EventListener annotated method can now alternatively
define the event type(s) to listen to via the "classes" attributes (that
is aliased to "value").
Something like
@EventListener({FooEvent.class, BarEvent.class})
public void handleFooBar() { .... }
Issue: SPR-13156
In AnnotatedElementUtils, all methods pertaining to merging annotation
attributes have been renamed to "getMerged*()" and "findMerged*()"
accordingly. Existing methods such as getAnnotationAttributes(..) have
been deprecated in favor of the more descriptive "merged" variants.
This aligns the naming conventions in AnnotatedElementUtils with those
already present in AnnotationReadingVisitorUtils.
The use of "annotationType" as a variable name for the fully qualified
class name of an annotation type has been replaced with
"annotationName" in order to improve the readability and intent of the
code base.
In MetaAnnotationUtils.AnnotationDescriptor, getMergedAnnotation() has
been renamed to synthesizeAnnotation(), and the method is now
overridden in UntypedAnnotationDescriptor to always throw an
UnsupportedOperationException in order to avoid potential run-time
ClassCastExceptions.
Issue: SPR-11511
This commit introduces support for finding annotations on abstract,
bridge, and interface methods in AnnotatedElementUtils.
- Introduced dedicated findAnnotationAttributes() methods in
AnnotatedElementUtils that provide first-class support for
processing methods, class hierarchies, interfaces, bridge methods,
etc.
- Introduced find/get search algorithm dichotomy in
AnnotatedElementUtils which is visible in the public API as well as
in the internal implementation. This was necessary in order to
maintain backwards compatibility with the existing API (even though
it was undocumented).
- Reverted all recent changes made to the "get semantics" search
algorithm in AnnotatedElementUtils in order to ensure backwards
compatibility, and reverted recent changes to
JtaTransactionAnnotationParser and SpringTransactionAnnotationParser
accordingly.
- Documented internal AnnotatedElementUtils.Processor<T> interface.
- Enabled failing tests and introduced
findAnnotationAttributesFromBridgeMethod() test in
AnnotatedElementUtilsTests.
- Refactored ApplicationListenerMethodAdapter.getCondition() and
enabled failing test in TransactionalEventListenerTests.
- AnnotationUtils.isInterfaceWithAnnotatedMethods() is now package
private.
Issue: SPR-12738, SPR-11514, SPR-11598
This commit introduces support in AnnotatedElementUtils for finding
annotations declared on interfaces at the type level.
NB: this commit does not include support for finding annotations
declared on interface methods.
In order to maintain backward compatibility with @Transactional
annotation attribute processing, a new getAnnotationAttributes() method
has been added to AnnotatedElementUtils that provides a flag to control
whether interfaces should be searched.
SpringTransactionAnnotationParser and JtaTransactionAnnotationParser
have been updated accordingly to ensure that interfaces are not
unintentionally searched in the @Transactional resolution process.
This commit also introduces additional tests and updates TODOs for
SPR-12738.
Issue: SPR-12944, SPR-12738
Prior to this commit, the search algorithm used by the
findAnnotation(Method, Class) method in AnnotationUtils only found
direct annotations or direct meta-annotations (i.e., one level of
meta-annotations).
This commit reworks the search algorithm so that it supports arbitrary
levels of meta-annotations on methods. To make this possible, a new
findAnnotation(AnnotatedElement, Class) method has been introduced in
AnnotationUtils.
This fix also allows for the @Ignore'd tests in
TransactionalEventListenerTests to be re-enabled.
Issue: SPR-12941
Update the application event listener infrastructure to support events
that are processed according to a transactional phase.
Introduce EventListenerFactory that can be implemented to provide support
for additional event listener types. TransactionalEventListener is a new
annotation that can be used in lieu of the regular EventListener. Its
related factory implementation is registered in the context automatically
via @EnableTransactionManagement or <tx:annotation-driven/>
By default, a TransactionalEventListener is invoked when the transaction
has completed successfully (i.e. AFTER_COMMIT). Additional phases are
provided to handle BEFORE_COMMIT and AFTER_ROLLBACK events.
If no transaction is running, such listener is not invoked at all unless
the `fallbackExecution` flag has been explicitly set.
Issue: SPR-12080
Fix a regression introduced by 961574bd17 that prevents a proper lookup
of the default transaction manager by name as the absence of a qualifier
is represented by an empty string (passing the faulty null check).
Issue: SPR-12577
One more (and hopefully last) attempt at making sure
determineTransactionManager does not break existing use cases.
This commit prevents any lookup if no transaction attributes are set
which is more compliant with the original version and prevents a lookup
if a non existing bean name is provided explicitly (as it can be the case
with Spring Boot).
Issue: SPR-12541
The fix in cec26e9 for SPR-12541 actually introduced a regression
when the interceptor is enabled on a method that does not require any
transaction. In such a case we try to locate the default
PlatformTransactionManager instead of just returning what we have (that
is null).
This commit updates the determineTransactionManager condition again to
take that use case into account again.
Issue: SPR-12541
Previously, cache transaction managers may be retained outside the
boundaries of an application context with AspectJ since an aspect is
basically a singleton for the current class loader.
This commit adds a "clearTransactionManagerCache" that is similar to the
"clearMetadataCache" introduced in CacheAspectSupport: whenever the
context is disposed, the cache is cleared to remove any reference to a
transaction manager defined by that context.
Issue: SPR-12518
SPR-11954 introduced a regression that when the "default" transaction
manager is cached, qualified transaction managers are not taken into
account anymore.
This commit rework the "determineTransactionManager" condition to
favor qualifier and "named" transaction managers. If none of these apply,
the default transaction manager is used as it should.
Also reworked the caching infrastructure so that a single cache holds
all transaction manager instances.
Issue: SPR-12541
This commit adds the missing 4.1 XSDs for the following components:
* spring-aop
* spring-context
* spring-jee
* spring-lang
* spring-tx
* spring-util
These are strictly identical to the definition of the 4.0 XSDs.
Issue: SPR-11990
Prior to this commit, cache operations mentioning a qualifier led to
a lookup for the same PlatformTransactionManager over and over again.
The same applied when a transactionManager bean name was specified on
the interceptor.
This commit adds a cache to store the reference of such transaction
managers. As a convenience, the default PlatformTransactionManager is
also initialized if it has not been through configuration.
Issue: SPR-11954
This commit adds a test that reproduces the behaviour described in
SPR-11915 and validates that the fix introduced in f8b6114440 works
as expected.
Issue: SPR-11915
Clean up compiler warnings in the tests of spring-tx. This commit
adds type parameters to all the types (mostly `List` and `Map`). In
addition it uses Java 5 autoboxing to get rid of several `new Integer`
(except in cases where it's needed).
After this commit the only warnings in spring-tx left are in
`TransactionAttributeSourceTests`` that code would never compile with
generics.
