Prior to this commit, the size of the ApplicationContext cache in the
Spring TestContext Framework could grow without bound, leading to
issues with memory and performance in large test suites.
This commit addresses this issue by introducing support for setting the
maximum cache size via a JVM system property or Spring property called
"spring.test.context.cache.maxSize". If no such property is set, a
default value of 32 will be used.
Furthermore, the DefaultContextCache has been refactored to use a
synchronized LRU cache internally instead of a ConcurrentHashMap. The
LRU cache is a simple bounded cache with a "least recently used" (LRU)
eviction policy.

This commit documents the @Ignore'd test to explain that Spring does not
support a hybrid approach for annotation attribute overrides with
transitive implicit aliases.

Prior to this commit, HTTP clients relying on the JDK HTTP client would
not properly reuse existing TCP connections (i.e. HTTP 1.1 persisten
connection). The SimpleClientHttpResponse would close the actual connection once the
response is handled.
As explained in the JDK documentation
(http://docs.oracle.com/javase/8/docs/technotes/guides/net/http-keepalive.html)
HTTP clients should do the following to allow resource reuse:
* consume the whole HTTP response content
* close the response inputstream once done
This commit makes sure that the response content is
totally drained and then the stream closed (and not the connection).

This commit introduces a boolean alwaysProcesses() method in the
Processor API which allows for simplification across all search
algorithms within AnnotatedElementUtils.
Specifically, it is no longer necessary for process() methods to verify
that the supplied annotation is actually the sought target annotation.
In addition, duplicated code has been extracted into common methods
(e.g., hasMetaAnnotationTypes()) and common Processor implementations
(e.g., AlwaysTrueBooleanAnnotationProcessor).
This commit picks up where 2535469099 left off with added support for
"get" search semantics for merged repeatable annotations.
Specifically, this commit introduces a new
getMergedRepeatableAnnotations() method in AnnotatedElementUtils.
Issue: SPR-13973
This commit picks up where a5139f3c66 left off with added support for
"get" search semantics for multiple merged annotations.
Specifically, this commit introduces a new getAllMergedAnnotations()
method in AnnotatedElementUtils.
Issue: SPR-13486
Prior to this commit, AnnotationUtils supported searching for
repeatable annotations even if the repeatable annotation was declared
on a custom stereotype annotation. However, there was no support for
merging of attributes in composed repeatable annotations. In other
words, it was not possible for a custom annotation to override
attributes in a repeatable annotation.
This commit addresses this by introducing
findMergedRepeatableAnnotations() methods in AnnotatedElementUtils.
These new methods provide full support for explicit annotation
attribute overrides configured via @AliasFor (as well as
convention-based overrides) with "find semantics".
Issue: SPR-13973
Prior to this commit it was possible to search for the 1st merged
annotation above an annotated element. It was also possible to search
for annotation attributes aggregated from all annotations above an
annotated element; however, it was impossible to search for all
composed annotations above an annotated element and have the results as
synthesized merged annotations instead of a multi-map of attributes.
This commit introduces a new findAllMergedAnnotations() method in
AnnotatedElementUtils that finds all annotations of the specified type
within the annotation hierarchy above the supplied element. For each
such annotation found, it merges that annotation's attributes with
matching attributes from annotations in lower levels of the annotation
hierarchy and synthesizes the results back into an annotation of the
specified type. All such merged annotations are collected and returned
as a set.
Issue: SPR-13486
This commit introduces tests that verify the status quo for finding
multiple merged composed annotations on a single annotated element.
Issue: SPR-13486
Prior to this commit, it was possible that implicit aliases and
transitive implicit aliases (configured via @AliasFor) might not be
honored in certain circumstances, in particular if implicit aliases
were declared to override different attributes within an alias pair in
the target meta-annotation.
This commit addresses this issue by ensuring that all aliased
attributes in the target meta-annotation are overridden during the
merge process in AnnotatedElementUtils.
In addition, concrete default values for attributes in a
meta-annotation declaration can now be effectively shadowed by
transitive implicit aliases in composed annotations.
Issue: SPR-14069
This commit primarily allows for a `SynthesizingMethodParameter` to be
created for a `Constructor` parameter but also introduces an additional
overloaded constructor from `MethodParameter`.
Issue: SPR-14054
This commit picks up where 8ff9e818a5
left off.
Specifically, this commit introduces support that allows a single
element attribute to override an array attribute with a matching
component type when synthesizing annotations (e.g., in annotations
synthesized from attributes that have been merged from the annotation
hierarchy above a composed annotation).
Issue: SPR-13972
Before this commit, specifying the charset to use with produces or
consumes @RequestMapping attributes resulted in default charset
loss. That was really annoying for JSON for example, where using
UTF-8 charset is mandatory in a lot of use cases.
This commit adds a defaultCharset property to
AbstractHttpMessageConverter in order to avoid losing the
default charset when specifying the charset with these
@RequestMapping attributes.
It changes slightly the default behavior (that's why we have waited
4.3), but it is much more error prone, and will match with most
user's expectations since the charset loss was accidental in most
use cases (users usually just want to limit the media type supported
by a specific handler method).
