This commit introduces Servlet.fn, a servlet-based version of
WebFlux.fn, i.e. HandlerFunctions and RouterFunctions.
This commit contains the web framework only, further commits provide
tests and DispatcherServlet integration.
See gh-21490
Prior to this commit, documentation for WebJar support referenced the
webjars-locator artifact; however, Spring now uses the
webjars-locator-core artifact.
This commit updates the documentation to reflect this.
Closes gh-22613
Typically a straight up equals as well as Collections#contains
checks for MediaType.ALL is susceptible to the presence of
media type parameters.
This commits adds equalsTypeAndSubtype as well as an
isPresentIn(Collection<MimeType>) methods to MimeType to faciliate
with checks for MediaType.ALL.
Issue: SPR-17550
Prior to this change, ResourceUrlEncodingFilter would try to resolve
the resource path using request URL without removing fragment first,
whereas only paths should be used.
This commit synchronizes behavior of ResourceUrlEncodingFilter with
behavior of ResourceUrlProvider.
Issue: SPR-17535
Prior to this commit, `ResourceTransformerSupport.toAbsolutePath`
would call `StringUtils.applyRelativePath` in all cases. But this
implementation is prepending the given path even if the relative path
starts with `"/"`.
This commit skips the entire operation if the given path is absolute,
i.e. it starts with `"/"`.
Issue: SPR-17432
Prior to this commit, the `ResourceUrlEncodingFilter` would wrap the
response and keep a reference to the request. When
`HttpServletResponse.encodeURL` is later called during view rendering,
the filter looks at the request and extracts context mapping information
in order to resolve resource paths in views.
This approach is flawed, when the filter is used with JSPs - if the
request is forwarded to the container by the `InternalResourceView`,
the request information is overwritten by the container. When the view
is being rendered, the information available in the request is outdated
and does not allow to correctly compute that context mapping
information.
This commit ensures that that information is being extracted from the
request as soon as the `ResourceUrlProvider` is set as a request
attribute.

The fix for SPR-17178 switched from debug to warn level warning for
all sub-classes of AbstractHandlerExceptionResolver where the request
concerned the DefaultHandlerExceptionResolver only.
This commit restores the original DEBUG level logging that was in
AbstractHandlerExceptionResolver from before SPR-17178. In addition
DefaultHandlerExceptionResolver registers a warnLogCategory by default
which enables warn logging and hence fulfilling the original goal
for SPR-17178.
Issue: SPR-17383
This reverts commit 162112.
Instead we'll go for a bigger rollback of the change from SPR-17178 so
that only DefaultHandlerExceptionResolver does warn logging by default.

1. Helper method to eliminate duplication in formatting (de-)serialized
values for logging introduced with prior commit #e62298.
2. Helper method for TRACE vs DEBUG logging with different details.
Issue: SPR-17254
At DEBUG show up to 100 chars, at TRACE show full formatted value.
Note that the formatValue helper method is duplicated a number of times
in this commit. A utility method will likely be added in spring-core
through an extra commit.

This commit represents a best effort attempt at fixing remaining
"a" vs. "an" grammatical errors related links specified via a fully
qualified class name.

This commit handles "empty" cases for `ResponseEntity` controller
handler return types when wrapped with a `java.util.Optional` in Spring
MVC or a single `Publisher` like `Mono`.
Given the following example for Spring MVC:
```
@GetMapping("/user")
public Optional<ResponseEntity<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok);
}
```
If the resulting `Optional` is empty, Spring MVC will infer a
`ResponseEntity` with an empty body and a 404 HTTP response status.
The same reasoning is applied to Spring WebFlux with Publisher types:
```
@GetMapping("/user")
public Mono<ResponseEntity<User>> fetchUser() {
Mono<User> user = //...
return user.map(ResponseEntity::ok);
}
```
This feature is only valid for `HttpEntity` return types and does not
apply to `@ResponseBody` controller handlers.

This commit allows to specify a custom CorsConfigurationSource
in AbstractHandlerMapping (both Servlet and Reactive variants).
AbstractHandlerMapping#getCorsConfigurations method is now
deprecated.
Issue: SPR-17067
This commit ignores errors like TransformerFactoryConfigurationError
that can be thrown when instantiating SourceHttpMessageConverter on
platforms where no TransformerFactory implementation is available,
like when compiling/running as GraalVM native images.
Issue: SPR-17007
See Javadoc on UriComponentsBuilder#uriVariables for details.
This helps to prepare for SPR-17027 where the MvcUriComponentsBuilder
already does a partial expand but was forced to build UriComonents
and then create a new UriComponentsBuilder from it to continue. This
change makes it possible to stay with the same builder instance.
Issue: SPR-17027
Given "/{foo}" and "/a=42;c=b", previously that would be treated as a
sequence of matrix vars with an empty path variable. After the change
the path variable "foo" is "a=42".
This should be ok for backawards compatibility since it's unlikely for
anything to rely on an empty path variable.
Issue: SPR-11897
The HandlerMethodParameter arrangement uses an approach similar to ModelAttributeMethodProcessor's FieldAwareConstructorParameter, merging the local parameter annotations with interface-declared annotations.
Issue: SPR-11055
Like CookieLocaleResolver, LocaleChangeInterceptor parses both locale formats by default now. Since it does not need to render the locale, its languageTagCompliant property is not relevant anymore at all.
The parseLocale method in StringUtils validates the locale value now and turns an empty locale into null, compatible with parseLocaleString behavior and in particular aligned with web locale parsing needs.
Issue: SPR-16700

This commit restricts the support of `"Content-Range"` when returning
`Resource` instances from Controllers - now only "HTTP 200 OK" responses
will be considered, as Controllers might want to handle content range
themselves.

Polish a few issue identified when adding checkstyle to the
build. Although checkstyle is not enforcing rules on tests,
these are a few minor changes that are still worth making.
Issue: SPR-16968
Reorganize imports to ensure consistent ordering. This commit also
expands any `.*` static imports in favor of using fully-qualified
method references.
Issue: SPR-16968
Update all classes so that inner classes are always last. Also
ensure that utility classes are always final and have a private
constructor and make exceptions final whenever possible.

Prior to this commit, the generated POMs for Spring Framework modules
would contain unneeded/harmful information from the Spring Framework
build:
1. The BOM imports applied to each module by the dependency
management plugin, for example for Netty or Reactor Netty.
Spring should not export that opinion to its POMs.
2. The exclusion of "org.slf4:jcl-over-slf4j" from *all* dependencies,
which made the POMs much larger than necessary and suggested to
developers that they should exclude it as well when using all those
listed dependencies. In fact, only Apache Tiles currently brings that
transitively.
This commit removes that information from the POMs.
The dependencyManagement Gradle plugin is disabled for POM generation
and we manually resolve the dependency versions during the generation
phase.
The Gradle build is streamlined to exclude "org.slf4:jcl-over-slf4j"
only when necessary.
Issue: SPR-16893
The key in CachingResourceResolver now includes the "Accept-Encoding"
request header cleaned to exclude "*", "identity", and parameters, and
also sorted alphabetically.
For encoded resources the response now includes a response header with
"Vary: Accept-Encoding".
Issue: SPR-16381
The new EncodedResourceResolver is a generalized version of
GzipResourceResolver that can be configured to support different
content codings, by "br" and "gzip".
GzipResourceResolver is now deprecated.
Issue: SPR-16381
This commit removes all places where forwarded headers are checked
implicitly, on an ad-hoc basis.
ForwardedHeaderFilter is expected to be used instead providing
centralized control over using or discarding such headers.
