Prior to this commit, the documentation in AnnotationUtils was
inconsistent, and at times even misleading, with regard to finding
annotations that are "present" or "directly present" on annotated
elements.
This commit defines the terminology used within AnnotationUtils and
introduces the explicit notion of "meta-present" to denote that
annotations are present within annotation hierarchies above annotated
elements.
Issue: SPR-13030
This commit updates the "get semantics" search algorithm used in
`AnnotatedElementUtils` so that locally declared 'composed annotations'
are favored over inherited annotations.
Specifically, the internal `searchWithGetSemantics()` method now
searches locally declared annotations before searching inherited
annotations.
All TODOs in `AnnotatedElementUtilsTests` have been completed, and all
ignored tests have been reinstated.
Issue: SPR-11598
This commit improves the documentation for AnnotationUtils and
AnnotatedElementUtils by explaining that the scope of most annotation
searches is limited to finding the first such annotation, resulting in
additional such annotations being silently ignored.
Issue: SPR-13015
In general, the Spring Framework aims to construct error message
strings only if an actual error has occurred. This seems to be the
common pattern in the codebase and saves both CPU and memory. However,
there are some places where eager error message formatting occurs
unnecessarily.
This commit addresses this issue in the following classes:
AdviceModeImportSelector, AnnotationAttributes, and
ReadOnlySystemAttributesMap.
The change in ReadOnlySystemAttributesMap also avoids a potential
NullPointerException.
Issue: SPR-13007
Prior to this commit, the `getAnnotation()` method in `TypeDescriptor`
only supported a single level of meta-annotations. In other words, the
annotation hierarchy would not be exhaustively searched.
This commit provides support for arbitrary levels of meta-annotations
in `TypeDescriptor` by delegating to `AnnotationUtils.findAnnotation()`
within `TypeDescriptor.getAnnotation()`.
Issue: SPR-12793
Prior to this commit, AntPathMatcher would not correctly combine a path
that ends with a separator with a path that starts with a separator.
For example, `/foo/` + `/bar` combined into `/foo//bar`.
Specifically, this commit:
- Removes the duplicated separator in combined paths
- Improves RequestMappingInfo's toString() representation
- Fixes Javadoc formatting in AntPathMatcher
- Polishes AntPathMatcherTests
- Polishes Javadoc in AbstractRequestCondition
Issue: SPR-12975
This commit picks up where SPR-11483 left off, with the goal of
eliminating all unnecessary inspection of core JDK annotations in
Spring's annotation search algorithms in AnnotatedElementUtils and
AnnotationMetadataReadingVisitor.
Issue: SPR-12989
- Methods which search for a specific annotation now properly ensure
that the sought annotation was actually found.
- Both the "get" and the "find" search algorithms no longer needlessly
traverse meta-annotation hierarchies twice.
- Both the "get" and the "find" search algorithms now properly
increment the metaDepth when recursively searching within the
meta-annotation hierarchy.
- Redesigned getMetaAnnotationTypes() so that it doesn't needlessly
search irrelevant annotations.
- Documented and tested hasMetaAnnotationTypes().
- Documented isAnnotated().
Issue: SPR-11514
This commit documents the status quo for the getMetaAnnotationTypes()
method in AnnotatedElementUtils and adds appropriate regression tests to
AnnotatedElementUtilsTests.
In addition, this commit also introduces a SimpleAnnotationProcessor
base class in AnnotatedElementUtils.
Issue: SPR-11514
This commit consistently documents the 'element' and 'annotationType'
method arguments throughout AnnotatedElementUtils.
In addition, this commit introduces assertions against preconditions
for all 'element' and 'annotationType' method arguments.
Issue: SPR-11514
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
- The exception message now mentions lacking to-Object method as well.
- Documented explicit lacking support for toString() for conversions.
- Introduced dedicated has*() methods for greater clarity and to reduce
code duplication.
- Static factory methods (i.e., of, from, valueOf) are now supported for
conversion to a String.
- Now correctly using @Test(expected=...) where appropriate.
- Renamed DefaultConversionTests to DefaultConversionServiceTests.
- Moved all tests related to DefaultConversionService from
GenericConversionServiceTests to DefaultConversionServiceTests.
- No longer printing to System.out.
- Removed all duplicate instantiation of conversion services.
- Now using Java 8 streams to simplify implementations of custom test
converters. Also using streams in tests where appropriate.
This commit introduces support for HTTP byte ranges in the
ResourceHttpRequestHandler. This support consists of a number of
changes:
- Parsing of HTTP Range headers in HttpHeaders, using a new HttpRange
class and inner ByteRange/SuffixByteRange subclasses.
- MIME boundary generation moved from FormHttpMessageConverter to
MimeTypeUtils.
- writePartialContent() method introduced in ResourceHttpRequestHandler,
handling the byte range logic
- Additional partial content tests added to
ResourceHttpRequestHandlerTests.
Issue: SPR-10805
Covers ReflectionUtils.doWithMethods as well as affected annotation post-processors.
Includes an extension of MethodMetadata for the detection of @Bean default methods.
Issue: SPR-12822
Issue: SPR-10919
Prior to this commit, the implementation of equals() in EncodedResource
was based solely on the resource and encoding. Thus, if a Charset were
specified instead of an encoding, invocations of equals() would not
work as expected.
This commit addresses this issue by including the charset in the
implementation of equals() and introducing corresponding tests in a new
EncodedResourceTests class. Furthermore, this commit makes
EncodedResource immutable and updates all Javadoc to reflect support
for the encoding and charset properties.
Issue: SPR-12767
This commit ensures Resources have consistent, non-empty, meaningful
implementations for getDescription(), thus ensuring that calls to
toString() (e.g., in log statements) no longer return an empty String.
This commit also polishes the Javadoc for various Resource
implementations.
Add StreamConverter to provide full support for converting
java.util.stream.Stream instances to and from collections or arrays.
Also attempt to convert the element type if necessary.
StreamConverter is registered by default in the DefaultConversionService
as long as Java8 is available.
Issue: SPR-12175
Previously, the `@Order` annotation was managed in an inconsistent way
when placed at the implementation level. For simple beans, it was
discovered properly but wasn't for beans requiring a proxy.
OrderComparator.SourceProvider now explicitly allows to return several
order sources; the default implementation returns not only the factory
method (if any) but also the target class if it happens to be different
from the class of the bean.
