This change modifies the SettableListenableFuture implementation to use
internally a ListenableFutureTask created with a "settable" Callable.
Issue: SPR-11614
A SettableListenableFuture implementation of Spring's ListenableFuture
The class is inspired by Google Guava’s
com.google.common.util.concurrent.SettableFuture, but this
implementation uses ReentrantReadWriteLock and CountDownLatch
internally to handle thread synchronization.
Issue: SPR-11614
After this change, java.util.Optional is supported with @RequestParam,
@RequestHeader, and @MatrixVariable arguments in Java 8. When Optional
is used the required flag is effectively ignored.

Prior to this commit, AntPathMatcher had been refactored for SPR-6741.
During that process, a key feature has been removed:
When comparing two patterns, pattern elements (*, {}, etc) are counted
to score those patterns. When a pattern ends with ".*", the ending
wildcard should not be counted against pattern elements for this
pattern.
This commit reintroduces that behavior.
Issue: SPR-6741
Prior to this commit, "**" and "*" pattern elements had
the same priority when comparing two patterns.
So when comparing several patterns, the computed order was:
1- /hotels/{hotel}/bookings/{booking}
2- /hotels/**
3- /hotels/{hotel}/bookings/{booking}/customer/{customer}
This commit updates the comparator so that patterns ending
with "**" (a.k.a "catch-all" patterns) are less specific than
the others; in the previous example, the 2nd pattern would
then end up last.
This commit also optimizes the comparator implementation.
Issue: SPR-6741
This commit introduces OrderProvider and OrderProviderComparator, two
interfaces designed to externalize how a collection of element is sorted
according to their order value.
FactoryAwareOrderProvider is an OrderProvider implementation that knows
about the objects to order and the corresponding BeanFactory instance.
This allows to retrieve additional metadata about the actual instances
to sort, such as its factory method.
A @Bean method can now holds an additional @Order to define the order
value that this bean should have when injected as part of a collection
or array.
Issue: SPR-11310
This commit separates the BackOff configuration from an actual
execution. BackOffExecution now contains all the state of a
particular execution and BackOff is only meant to start (i.e.
create) a new execution.
The method "reset" has been removed as its no longer necessary:
when an execution does not need to be used for a given operation
anymore it can be simply discarded.
Issue: SPR-11746
Prior to this commit, DefaultMessageListenerContainer was recovering
on failure using a fixed time interval, potentially in an infinite way.
This commit adds an extra "backoff" property to the container that
permits to fine tune the recovery interval using a BackOff instance.
FixedBackOff provides a fixed interval between two attempts and a
maximum number of retries. ExponentialBackOff increases an initial
interval until a maximum interval has been reached. A BackOff instance
can return a special "STOP" time value that indicates that no further
attemps should be made. DefaultMessageListenerContainer uses this
value to stop the container.
protected method "sleepInbetweenRecoveryAttempts" has been renamed
to "applyBackOff" and now returns a boolean that indicate if the
back off has been applied and a new attempt should now be made.
Issue: SPR-11746
Prior to this commit, invoking the getMergedAnnotationAttributes()
method in AnnotationReadingVisitorUtils resulted in mutation of the
internal state of the ASM-based annotation metadata supplied to the
method.
This commit fixes this issue by making a copy of the original
AnnotationAttributes for the target annotation before merging attribute
values from the meta-annotation hierarchy.
This commit also introduces a slight performance improvement by
avoiding duplicate processing of the attributes of the target
annotation.
Issue: SPR-11710
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 rationalizes the use of @Order so that the standard
@Priority annotation can be used instead. The handling of both
annotations are now defined in OrderUtils.
This also updates the link to the JavaEE API so that we refer to
JavaEE7 instead of JavaEE6.
Issue: SPR-11639
Improved the SAX to StAX (and vice-versa) bridge exposed via StaxUtils.
The old integration had some issues with namespace declaration
attributes, brought to light in a XMLUnit upgrade.
Issue: SPR-11549
Changes introduced in conjunction with issue SPR-11475 altered the
behavior of StandardAnnotationMetadata such that annotations could be
detected on superclasses, specifically in the case where the
AnnotatedElementUtils.getAllAnnotationAttributes() method is invoked to
obtain multiple annotations of the same type (on the lowest level in the
class hierarchy), as is the case for @Profile and @Conditional.
This commit partially reverts these changes as follows:
- All methods in AnnotatedElementUtils now set the
traverseClassHierarchy to false, thereby effectively reverting the
changes made in commit 1d30bf83a0.
Note, however, that the changes made to AnnotationUtils remain in
place.
- Introduced tests in AnnotationMetadataTests that verify behavior
present in Spring Framework 4.0.2 and earlier.
- Updated tests in AnnotatedElementUtilsTests so that they pass against
the reverted changes (i.e., align with the behavior present in Spring
Framework 4.0.2 and earlier).
- Refined Javadoc in AnnotationMetadata with regard to annotations
being "present" vs. "defined".
- Refined Javadoc in AnnotatedTypeMetadata.
Issue: SPR-11475, SPR-11595
Prior to this commit, the ShallowEtagHeaderFilter did not use the
content length given by the content generator to set the
ByteArrayOutputStream's buffer size.
This can lead to performance issues for large content since the buffer
grows as the content is being written.
This commit adds a new ByteArrayOutputStream variant called
ResizableByteArrayOutputStream. This implementation has public methods
for modifying the internal buffer size and does not synchronize on
buffer access.
This commit also make use of this new variant in
ShallowEtagHeaderFilter.
Issue: SPR-8271
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
Also uses addAll instead of iteration over untyped collection now, supporting optimized addAll in target collection type, and avoids repeated getElementTypeDescriptor calls.
Issue: SPR-11479
Prior to this commit, the implementations of findAnnotation() in
AnnotationUtils and getAnnotationAttributes() in AnnotatedElementUtils
favored inherited annotations and inherited composed annotations over
composed annotations that are declared closer to the starting class
passed to these methods.
This commit addresses this issue as follows:
- Refactored AnnotationUtils to use getDeclaredAnnotation() and
getDeclaredAnnotations() instead of getAnnotation() and
getAnnotations() where appropriate.
- AnnotatedElementUtils.doProcess() supports a traverseClassHierarchy
flag to control whether the class hierarchy should be traversed,
using getDeclaredAnnotations() instead of getAnnotations() if the
flag is true.
- Overhauled Javadoc in AnnotatedElementUtils.
Issue: SPR-11475
This commit introduces a new isInJavaLangAnnotationPackage(Annotation)
method in AnnotationUtils. This method is now used in AnnotationUtils,
AnnotatedElementUtils, and MetaAnnotationUtils to ensure that search
algorithms do no search for meta-annotations on annotations in the
"java.lang.annotation" package.
The following are some empirical results from this change:
- The number of times that the findAnnotation(Class,Class,Set) method in
AnnotationUtils is recursively invoked while executing
AnnotationUtilsTests drops from 51 to 29.
- The number of times that the process(AnnotatedElement) method in
AnnotationUtils.AnnotationCollector is recursively invoked while
executing AnnotationUtilsTests.getRepeatableFromMethod() drops
from 16 to 2.
- The number of times that the doProcess() method in
AnnotatedElementUtils is recursively invoked while executing the
"getAnnotationAttributes() On MetaCycleAnnotatedClass with missing
target meta-annotation" test in AnnotatedElementUtilsTests drops
from 23 to 5.
- The number of times that the findAnnotationDescriptor(Class,Set,Class)
method in MetaAnnotationUtils is recursively invoked while executing
the "findAnnotationDescriptor() on MetaCycleAnnotatedClass with
missing target meta-annotation" test in MetaAnnotationUtilsTests drops
from 16 to 8.
Issue: SPR-11483
Prior to this commit, AnnotationUtils.findAnnotation(Class, Class)
claimed to recursively search through annotations; however, only one
level of annotations was supported by the algorithm.
This commit alters the search algorithm so that nested meta-annotations
(i.e., meta-annotations on meta-annotations) are also supported.
Issue: SPR-11448
Prior to this commit several test classes named "*Test" were not
recognized as tests by the Gradle build. This is due to the configured
inclusion of '**/*Tests.*' which follows Spring's naming convention for
test classes.
This commit addresses this issue by:
- Renaming real test classes consistently to "*Tests".
- Renaming internal test classes to "*TestCase".
- Renaming @WebTest to @WebTestStereotype.
- Disabling broken tests in AnnoDrivenStaticEntityMockingControlTest.
- Modifying the Gradle build configuration so that classes ending in
either "*Tests" or "*Test" are considered test classes.

This in particular allows for specifying "spring.getenv.ignore" and "spring.beaninfo.ignore" in a local way within the application, in case that JVM-level system properties are locked.
Issue: SPR-9014
Issue: SPR-11297
Provided overloaded versions of `forField` and `forMethodParameter` that
accept a `ResolvableType` implementation type (as opposed to a Class).
Primarily added to allow resolution against implementation types that
have been created programmatically using `forTypeWithGenerics`.
