Ideally one would pass WebClient directly to HttpServiceProxyFactory,
but two need to remain decoupled. This commit adds static, shortcut
methods to WebClientAdapter to create an HttpServiceProxyFactory, thus
eliminating the step to wrap the WebClient.
Prior to this commit, Spring MVC and Spring WebFlux would not support
conditional requests with `If-Match` preconditions. As underlined in the
RFC9110 Section 13.1, those are related to the `If-None-Match`
conditions, but this time only performing requests if the resource
matches the given ETag.
This feature, and in general the `"*"` request Etag, are generally
useful to prevent "lost updates" when performing a POST/PUT request: we
want to ensure that we're updating a version with a known version or
create a new resource only if it doesn't exist already.
This commit adds `If-Match` conditional requests support and ensures
that both `If-Match` and `If-None-Match` work well with `"*"` request
ETags.
We can't rely on `checkNotModified(null)`, as the compiler can't decide
between method variants accepting an ETag `String` or a Last Modified
`long`. Instead, developers should use empty ETags `""` to signal that
no resource is known on the server side.

A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.
Closes gh-28433
Prior to this commit, the `name` attribute in @ModelAttribute was not
supported when using WebFlux. This is because MethodParameter was used
instead of SynthesizingMethodParameter when retrieving the
@ModelAttribute annotation. In other words, @AliasFor was not honored
because the annotation was not synthesized. Consequently, only the
`value` attribute was supported in WebFlux when specifying a custom name
via @ModelAttribute.
This commit fixes this by using SynthesizingMethodParameter to retrieve
the @ModelAttribute annotation.
Closes gh-28423
This commit introduces the PartEvent API. PartEvents are either
- FormPartEvents, representing a form field, or
- FilePartEvents, representing a file upload.
The PartEventHttpMessageReader is a HttpMessageReader that splits
multipart data into a stream of PartEvents. Form fields generate one
FormPartEvent; file uploads produce at least one FilePartEvent. The last
element that makes up a particular part will have isLast set to true.
The PartEventHttpMessageWriter is a HttpMessageWriter that writes a
Publisher<PartEvent> to a outgoing HTTP message. This writer is
particularly useful for relaying a multipart request on the server.
Closes gh-28006
This commit introduces explicit HEAD support in Spring
MVC's ResourceHttpRequestHandler and WebFlux's ResourceWebHandler,
adding just headers but no body.
Closes gh-28291
This commit ensures that any resources created for multipart handling,
obtained via ServerWebExchange.getMultipartData(), are automatically
deleted after handling the completing the response.
Resource for parts obtained via BodyExtractors::toMultipartData and
BodyExtractors::toParts are not cleaned automatically, and
should be cleaned via Part::delete.
Closes gh-27633
This commit contains changes made because of the introduction of
HttpStatusCode. In general, methods that used to return a HttpStatus
now return HttpStatusCode instead, and methods that returned raw status
codes are now deprecated.

Since the Nashorn JavaScript engine was removed in Java 15, these tests
will never be run on a Java 17+ JDK which is required as of Spring
Framework 6.0.

This commit makes sure that the response returned by coroutine handler
methods that return ResponseEntity<Flux> is unwrapped correctly.
Closes gh-27809
All Spring MVC exceptions from spring-web, now implement ErrorResponse
and expose HTTP error response information, including an RFC 7807 body.
See gh-27052
ErrorResponse represents a complete error response with status, headers,
and an RFC 7807 ProblemDetail body.
ErrorResponseException implements ErrorResponse and is usable on its
own or as a base class. ResponseStatusException extends
ErrorResponseException and now also supports RFC 7807 and so does its
sub-hierarchy.
ErrorResponse can be returned from `@ExceptionHandler` methods and is
mapped to ResponseEntity.
See gh-27052
ProblemDetail is a representation of an RFC 7807 "problem", and this
commits adds support for it in Spring MVC and WebFlux as a return value
from `@ExceptionHandler` methods, optionally wrapped with
ResponseEntity for headers.
See gh-27052
SocketUtils was introduced in Spring Framework 4.0, primarily to assist
in writing integration tests which start an external server on an
available random port. However, these utilities make no guarantee about
the subsequent availability of a given port and are therefore
unreliable. Instead of using SocketUtils to find an available local
port for a server, it is recommended that users rely on a server's
ability to start on a random port that it selects or is assigned by the
operating system. To interact with that server, the user should query
the server for the port it is currently using.
SocketUtils is now deprecated in 5.3.16 and will be removed in 6.0.
Closes gh-28052
In a small minority of cases, the multipart boundary can spread across
three incoming buffers.
Prior to this commit, MultipartParser.BodyState only supported two
buffers. If the boundary is spread across three buffers, the first
buffer of the three is sent as a whole, even though it contains the
first bytes of the boundary.
This commit fixes this bug, by enqueuing all prior buffers in a queue,
and emitting the ones that cannot contain boundary bytes.
Closes gh-27939
This commit introduces a dedicated (disabled) transferToWithUndertow()
test method to simplify debugging of transferTo issues with Undertow.
See gh-25310
Closes gh-27908
Instead of simply returning prematurely and allowing the tests to be
marked as SUCCESS, this commit uses a failed assumption to abort the
the trasferTo tests for Undertow, resulting in the parameterized test
invocation properly being marked as ABORTED.

This commit makes it possible to customize 404 responses generated by
RouterFunctionWebHandler, by throwing an ResponseStatusException
instead of returning a standard 404 response.
See gh-25358
Prior to this commit, ServerResponse headers would only be written if
there were no existing headers with the same name, thus making it
impossible to overwrite existing headers.
With the changes in this commit, headers are always written.

This commit changes DefaultClientResponse::createException to use
the ByteArrayDecoder, instead of converting to DataBuffers and
turning these into a byte array.

This commit also applies additional clean-up tasks such as the following.
- final fields
- diamond operator (<>) for anonymous inner classes
- multi-catch
This has only been applied to `src/main/java`.
ResponseEntityResultHandler nests correctly, only once for the ResponseEntity,
when there is a Mono adapted from a Kotlin Continuation.

PR gh-24470 introduced a regression for Android users by no longer
escaping closing curly braces in regular expressions.
This commit therefore partially reverts the changes made in 273812f9c5
for closing curly braces (`}`).

In order to catch Javadoc errors in the build, we now enable the
`Xwerror` flag for the `javadoc` tool. In addition, we now use
`Xdoclint:syntax` instead of `Xdoclint:none` in order to validate
syntax within our Javadoc.
This commit fixes all resulting Javadoc errors and warnings.
This commit also upgrades to Undertow 2.2.12.Final and fixes the
artifact names for exclusions for the Servlet and annotations APIs.
The incorrect exclusion of the Servlet API resulted in the Servlet API
being on the classpath twice for the javadoc task, which resulted in the
following warnings in previous builds.
javadoc: warning - Multiple sources of package comments found for package "javax.servlet"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.http"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.descriptor"
javadoc: warning - Multiple sources of package comments found for package "javax.servlet.annotation"

In order to be able to use text blocks and other new Java language
features, we are upgrading to a recent version of Checkstyle.
The latest version of spring-javaformat-checkstyle (0.0.28) is built
against Checkstyle 8.32 which does not include support for language
features such as text blocks. Support for text blocks was added in
Checkstyle 8.36.
In addition, there is a binary compatibility issue between
spring-javaformat-checkstyle 0.0.28 and Checkstyle 8.42. Thus we cannot
use Checkstyle 8.42 or higher.
In this commit, we therefore upgrade to spring-javaformat-checkstyle
0.0.28 and downgrade to Checkstyle 8.41.
This change is being applied to `5.3.x` as well as `main` in order to
benefit from the enhanced checking provided in more recent versions of
Checkstyle.

To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.

Prior to this commit, the `RouterFunctionMapping` WebFlux.fn variant
would set the `HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE` as an
exchange attribute. This is useful for instrumentation purposes.
The WebMvc.fn variant would not do the same; this would lead to
"UNKNOWN" path metrics tags.
This commit ensures that the `RouterFunctionMapping` WebMvc.fn variant
does set the `BEST_MATCHING_PATTERN_ATTRIBUTE` and
`BEST_MATCHING_HANDLER_ATTRIBUTE` request attributes.
Closes gh-26963
Prior to this commit, @ModelAttribute(binding=false) was honored with
Spring Web MVC but not with WebFlux.
This commit adds support for disabling binding via @ModelAttribute with
WebFlux by adding a check to resolveArgument(...) in
ModelAttributeMethodArgumentResolver.
Closes gh-26856
Prior to this commit, evaluating validation hints for
@javax.validation.Valid caused exceptions being raised when getting the
value of this annotation, which does not exist. Bypassing
AnnotationUtils.getValue() in those cases can improve performance by
avoiding the cost incurred by raising exceptions.
