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
(cherry picked from commit e1720d89fc)
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.
Issue: SPR-11384
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`.
Issue: SPR-11218
Apply consistent styling to new classes introduced in Spring 4.0.
- Javadoc line wrapping, whitespace and formatting
- General code whitespace
- Consistent Assert.notNull messages
Fix remaining Java compiler warnings, mainly around missing
generics or deprecated code.
Also add the `-Werror` compiler option to ensure that any future
warnings will fail the build.
Issue: SPR-11064
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.
Issue: SPR-11104
