In light of the refinements to ObjectUtils, this commit updates
SynthesizedMergedAnnotationInvocationHandler to use
ObjectUtils.nullSafeHashCode() and removes the now obsolete code in
SynthesizedMergedAnnotationInvocationHandler.
See gh-29051
This commit reverts the deprecation of CommandLinePropertySource and
SimpleCommandLinePropertySource, since we have discovered that Spring
Boot actively uses SimpleCommandLinePropertySource in
org.springframework.boot.SpringApplication.
Closes gh-31207
This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
Closes gh-29051
This commit revises the contribution for gh-25921 in the following ways.
- Use instanceof pattern matching
- Use List.of() and Map.of()
- Add missing @since tags
- Polish Javadoc
- Rename isNegativeNumber() to isNegativeNumberLiteral()
- Restructure InlineCollectionTests using @Nested, etc.
- Fix testListWithVariableNotCached() test: it previously set a SpEL
"variable" but tested a "property" in the root context object, which
effectively did not test anything.
- Introduce additional tests: listWithPropertyAccessIsNotCached(),
mapWithVariableIsNotCached(), and mapWithPropertyAccessIsNotCached().
This commit changes the way request attributes are handled in
RequestPredicates. Previously, the AND/OR/NOT predicates copied all
attributes in a map, and restored that when the delegate predicate(s)
failed.
Now, we only set the attributes when all delegates have succeeded.
Closes gh-30028
This commit ensures that both `ObservationRegsitry` and
`ServerRequestObservationConvention` beans are automatically detected in
the application context if they are unique. This aligns with the
existing behavior for all other builder methods.
Closes gh-31205
This commit refines CORS wildcard processing Javadoc to
provides more details on how wildcards are handled for
Access-Control-Allow-Methods, Access-Control-Allow-Headers
and Access-Control-Expose-Headers CORS headers.
For Access-Control-Expose-Headers, it is not possible to copy
the response headers which are not available at the point
when the CorsProcessor is invoked. Since all the major browsers
seem to support wildcard including on requests with credentials,
and since this is ultimately the user-agent responsibility to
check on client-side what is authorized or not, Spring Framework
continues to support this use case.
See gh-31143
AnnotationBeanNameGenerator was written before the introduction of the
MergedAnnotations API and therefore heavily relies on the
AnnotationMetadata abstraction and various helper methods for ASM
compatibility.
However, recent work on determineBeanNameFromAnnotation() has made it
apparent that we should use the MergedAnnotations API directly in
AnnotationBeanNameGenerator where feasible in order to avoid
unnecessary, repeated iterations/streams over the same annotation
metadata.
Closes gh-31203
This commit allows a custom code fragment to provide the code to
create a bean without relying on ConstructorResolver. This is especially
important for use cases that derive from the default behaviour and
provide an instance supplier with the regular runtime scenario.
This is a breaking change for code fragments providing a custom
implementation of the related methods. As it turns out, almost all of
them did not need the Executable argument. Configuration class parsing
is the exception, where it needs to provide a different constructor in
the case of the proxy. To make this use case possible,
InstanceSupplierCodeGenerator has been made public.
Closes gh-31117
