Create internal variants of the existing `AnnotationUtils` and
`AnnotatedElementUtils` classes and migrate the existing classes to
use them.
The internal variants will be used to check that the same results are
given as we migrate the utils methods to use the new `MergedAnnotations`
API.
See gh-22562
Add new `MergedAnnotations` and `MergedAnnotation` interfaces that
attempt to provide a uniform way for dealing with merged annotations.
Specifically, the new API provides alternatives for the static methods
in `AnnotationUtils` and `AnnotatedElementUtils` and supports Spring's
comprehensive annotation attribute `@AliasFor` features. The interfaces
also open the possibility of the same API being exposed from the
`AnnotationMetadata` interface.
Additional utility classes for collecting, filtering and selecting
annotations have also been added.
Typical usage for the new API would be something like:
MergedAnnotations.from(Example.class)
.stream(MyAnnotation.class)
.map(a -> a.getString("value"))
.forEach(System.out::println);
Closes gh-21697
Add a new test class to help cover annotation introspection failure
handling. These tests were previously missing and are important to
ensure that annotation util code changes don't introduce regressions.
See gh-21697
Add a public variant of `getDeclaredMethods` that defensively copies the
cached methods array. This is often more faster and more convenient
for users than calling `doWithLocalMethods`. We still retain most of the
benefits of the cache, namely fewer security manager calls and not as
many `Method` instances being created.
Closes gh-22580
Includes consistent bean class resolution in the enhancement step as well as general reflection optimizations for user-declared methods.
Closes gh-22420
The isCandidateClass mechanism is consistently used for a bypass check before method traversal attempts. While by default this is only bypassing standard java types, the same mechanism can be used with index metadata which indicates non-presence of certain annotations.
See gh-22420
Prior to this commit the documentation for annotation-based include and
exclude filters used with component scanning did not explicitly mention
the fact that annotations are considered a match if they are either
present or meta-present on candidate classes.
This commit improves the documentation in this regard.
See gh-22551
Prior to this commit, the exception message generated by
instantiateFactory() in SpringFactoriesLoader did not report the
offending class in the top-level exception message. The offending class
was in fact included in the message of the nested exception, but the
top-level exception message on its own was a bit misleading.
This commit improves the diagnostics for such failures by including the
offending class and the target factory type in the top-level exception
message.
Closes gh-22453
Before this commit, the return type for Kotlin suspending functions
(as returned by MethodParameter#getParameterType and
MethodParameter#getGenericReturnType methods) was incorrect.
This change leverages Kotlin reflection instead of Java one
to return the correct type.
Closes gh-21058
- Integration tests run with zero copy configuration.
- RSocketBufferLeakTests has been added.
- Updates in MessagingRSocket to ensure proper release
See gh-21987
Prior to this commit, repeated calls to `DataBuffer.write(CharSequence,
Charset)` would not write the given chars to the expected position in
the original buffer.
This commit fixes that by writing to the `outBuffer.position()`, offset
by the current `DataBuffer.writePosition()`.
Fixes gh-22484
