This commit adds the support of JMS annotated endpoint. Can be
activated both by @EnableJms or <jms:annotation-driven/> and
detects methods of managed beans annotated with @JmsListener,
either directly or through a meta-annotation.
Containers are created and managed under the cover by a registry
at application startup time. Container creation is delegated to a
JmsListenerContainerFactory that is identified by the containerFactory
attribute of the JmsListener annotation. Containers can be
retrieved from the registry using a custom id that can be specified
directly on the annotation.
A "factory-id" attribute is available on the container element of
the XML namespace. When it is present, the configuration defined at
the namespace level is used to build a JmsListenerContainerFactory
that is exposed with the value of the "factory-id" attribute. This can
be used as a smooth migration path for users having listener containers
defined at the namespace level. It is also possible to migrate all
listeners to annotated endpoints and yet keep the
<jms:listener-container> or <jms:jca-listener-container> element to
share the container configuration.
The configuration can be fine-tuned by implementing the
JmsListenerConfigurer interface which gives access to the registrar
used to register endpoints. This includes a programmatic registration
of endpoints in complement to the declarative approach. A default
JmsListenerContainerFactory can also be specified to be used if no
containerFactory has been set on the annotation.
Annotated methods can have flexible method arguments that are similar
to what @MessageMapping provides. In particular, jms listener endpoint
methods can fully use the messaging abstraction, including convenient
header accessors. It is also possible to inject the raw
javax.jms.Message and the Session for more advanced use cases. The
payload can be injected as long as the conversion service is able to
convert it from the original type of the JMS payload. By
default, a DefaultJmsHandlerMethodFactory is used but it can be
configured further to support additional method arguments or to
customize conversion and validation support.
The return type of an annotated method can also be an instance of
Spring's Message abstraction. Instead of just converting the payload,
such response type allows to communicate standard and custom headers.
The JmsHeaderMapper infrastructure from Spring integration has also
been migrated to the Spring framework. SimpleJmsHeaderMapper is based
on SI's DefaultJmsHeaderMapper. The simple implementation maps all
JMS headers so that the generated Message abstraction has all the
information stored in the protocol specific message.

Prior to this commit, only the java.lang.reflect.Method was used to
identify an annotated method. As a result, if different annotations
were placed on different methods (method overriding, interface
implementation) only the first one (cached) was used.
LazyParamAwareEvaluationContext was affected by the exact
same problem and has been also fixed.
Issue: SPR-11692
Prior to this commit, the CacheResolver was not used by Spring's
caching abstraction. This commit provides the necessary configuration
options to tune how a cache is resolved for a given operation.
CacheResolver can be customized globally, at the operation level or at
the class level. This breaks the CachingConfigurer class and a support
implementation is provided that implements all methods so that the
default is taken if it's not overridden. The JSR-107 support has been
updated as well, with a similar support class.
In particular, the static and runtime information of a cache
operation were mixed which prevents any forms of caching. As the
CacheResolver and the KeyGenerator can be customized, every operation
call lead to a lookup in the context for the bean.
This commit adds CacheOperationMetadata, a static holder of all
the non-runtime metadata about a cache operation. This is used
as an input source for the existing CacheOperationContext.
Caching the operation metadata in an AspectJ aspect can have side
effects as the aspect is static instance for the current ClassLoader.
The metadata cache needs to be cleared when the context shutdowns.
This is essentially a test issue only as in practice each application
runs in its class loader. Tests are now closing the context properly
to honor the DisposableBean callback.
Issue: SPR-11490
This commit adds support for the JSR-107 cache annotations alongside
the Spring's cache annotations, that is @CacheResult, @CachePut,
@CacheRemove and @CacheRemoveAll as well as related annotations
@CacheDefaults, @CacheKey and @CacheValue.
Spring's caching configuration infrastructure detects the presence of
the JSR-107 API and Spring's JCache implementation. Both
@EnableCaching and the cache namespace are able to configure the
required JCache infrastructure when necessary. Both proxy mode
and AspectJ mode are supported.
As JSR-107 permits the customization of the CacheResolver to use for
both regular and exception caches, JCacheConfigurer has been
introduced as an extension of CachingConfigurer and permits to define
those.
If an exception is cached and should be rethrown, it is cloned and
the call stack is rewritten so that it matches the calling thread each
time. If the exception cannot be cloned, the original exception is
returned.
Internally, the interceptors uses Spring's caching abstraction by default
with an adapter layer when a JSR-107 component needs to be called.
This is the case for CacheResolver and CacheKeyGenerator.
The implementation uses Spring's CacheManager abstraction behind the
scene. The standard annotations can therefore be used against any
CacheManager implementation.
Issue: SPR-9616
This commit adds a putIfAbsent method to the Cache interface. This
method offers an atomic put if the key is not already associated in
the cache.
Issue: SPR-11400
Prior to this commit, an exception thrown by an @Async void method
was not further processed as there is no way to transmit that
exception to the caller.
The AsyncUncaughtExceptionHandler is a new strategy interface that
can be implemented to handle unexpected exception thrown during the
invocation of such asynchronous method.
The handler can be specified using either the XML namespace or by
implementing the AsyncConfigurer interface with the EnableAsync
annotation.
Issue: SPR-8995
Prior to this commit, a cache that is added on-the-fly is not properly
decorated by the provided CacheManager implementation that supports
it (EhCache and JCache).
This commits adds an extra getMissingCache method to
the AbstractCacheManager that can be extended to provide a cache that
may exist in the native cache manager but is not yet known by the
spring abstraction.
Issue: SPR-11518
Prior to this commit, common cache operation settings had to be
repeated for every operation: cache name(s), custom cache manager
and custom key manager.
This commit introduces the @CacheConfig annotation to bet set at
class-level (either directly or as a meta-annotation). As the cache
name(s) can be rationalized there, the "value" of the various
annotations are no longer mandatory.
CacheAnnotationParser has an API breakage to be able to retrieve
information at class-level.
Issue: SPR-11316
It is now possible to specify the CacheManager to use per operation.
The related cache annotation now has an extra attribute that defines
the name of the CacheManager bean to use. The cache manager that
was previously used is therefore a 'default' cache manager (i.e. the
one to use if no custom cache manager has been set on the operation).
Issue: SPR-8696
This commit adds an extra parameter to the base @Cache method
annotations: keyGenerator. This parameter holds the name of the
KeyGenerator bean to use to compute the key for that specific
caching endpoint.
This gives therefore a third way to customize the key. These are:
1. Default KeyGenerator (global for all endpoints)
2. The 'key' attribute of the annotation, giving the SpEL expression to use
3. The 'keyGenerator' attribute of the annotation
The annotation attributes are therefore exclusive. Trying to specify
them both will result in an IllegalStateException.
The KeyGenerator to use for a given operation is cached on startup
so that multiple calls to it does not resolve the instance to use over and
over again.
Issue: SPR-10629
Prior to this commit, the codebase was using a mix of log4j.xml
and log4j.properties for test-related logging configuration. This
can be an issue as log4j takes the xml variant first when looking
for a default bootstrap configuration.
In practice, some modules declaring the properties variant were
taking the xml variant configuration from another module.
The general structure of the configuration has also been
harmonized to provide a standard console output as well as an
easy way to enable trace logs for the current module.
Prior to this commit, Spring supported meta-annotation attribute
overrides in custom composed annotations with reflection-based
annotation processing but not with ASM-based annotation processing.
This commit ensures that meta-annotation attribute overrides are
supported in AnnotationMetadataReadingVisitor.getAnnotationAttributes().
Issue: SPR-11574
Prior to this commit, AnnotationAttributesReadingVisitor treated Class
annotation attributes as Strings instead of Classes. As a result,
look-ups for Class attributes in meta-annotations failed with an
IllegalArgumentException.
This commit fixes this issue by consistently treating Class attributes
as Classes in AnnotationAttributesReadingVisitor.
Issue: SPR-11557
This commit introduces unit and integration tests that attempt to
reproduce the issue claimed by the reporter in SPR-11557. However, the
tests pass without any problems.
Issue: SPR-11557
Restored original singleton-only adaptInnerBeanName behavior, avoiding endless unique name calculation for every single prototype instance. Non-named inner BeanDefinition objects now suffixed with an identity hex code analogous to non-named XML bean definitions, largely avoiding naming collisions to begin with. After SPR-11246, post-processors can deal with unstable classes per bean name, so occasional collisions aren't a hard problem anymore.
Issue: SPR-11545
Prior to this commit, an array argument was not handled properly in
SimpleKey#equals and SimpleKey#hashCode. As a result, two method
invocations with the same array argument lead to two different keys
and therefore two different entries in the cache.
This commit uses deepEquals and deepHashCode to properly handle
methods that have arguments that are array types.
