Remove convenience Map that is to avoid. The only downside is that
getHandlerMethods requires a transformation but that should not be used frequently.

This commit introduces a way to change the PathPatternParser used in
PathPredicates, by way of a ChangePathPatternParserVisitor. This
visitor is used by both WebFluxConfigurationSupport and
WebMvcConfigurationSupport to make sure the configured parser is used.
Closes gh-23236
This commit introduces the DefaultMultipartMessageReader, a fully
reactive multipart parser without third party dependencies.
An earlier version of this code was introduced in fb642ce, but removed
again in 77c24aa because of buffering issues.
Closes gh-21659
List<T> support was added relatively late, incorrectly decoding each
part to T which means no way to decode a single part to List<T> and
thatis the most common case (vs multipart parts with the same name).
This behavior was further misaligned with Spring MVC as well as with
the behavior for T[].

Prior to this commit, if attributes were configured in the builder
returned by `ServerRequest.from(...)`, those attributes were not
available in the `ServerRequest` built by the builder. In addition, any
attributes in the original `ServerRequest` supplied to
`ServerRequest.from(...)` were also ignored.
This commit addresses this issue by ensuring that the attributes
configured via DefaultServerRequestBuilder are used as the attributes
in the resulting `ServerRequest`.
This commit also polishes the Javadoc in `ServerRequest` and
`ClientResponse` and avoids the use of lambda expressions in the
constructors for `DefaultServerRequestBuilder` and
`DefaultClientResponseBuilder`.
Closes gh-25106
Prior to this commit, the `VersionResourceResolver` implementations
would write a strong ETag HTTP response header with the resolved version
of the resource (the actual value depending on the chosen strategy).
This approach doesn't work well when combined with HTTP compression.
Web servers disable HTTP response copression in the presence of strong
ETags since mutating the response body would break the contract.
This commit changes this semantic and ensures that weak ETags are used
instead.
Closes gh-24898
When mutating a ServerHttpRequest or ClientResponse, the respective
builders no longer access cookies automatically which causes them to
be parsed and does so only if necessary. Likewise re-applying the
read-only HttpHeaders wrapper is avoided.
See gh-24680
Given that the body is a Flux<DataBuffer> there probably could be a
Flux<DataBuffer> body();
At least bodyToFlux(DataBuffer.class) which is used when mutating and
is a common case should not incur overhead.
See gh-24680
from() has the flaw of ignoring the body and it can't be fixed because
applications are guaranteed to be setting it already and if set twice
the builder drains the first body.
mutate() is a better fit in any case for what needs to be done in a
filter chain. It can be done more efficiently and is consistent with
similar options on the server side.
See gh-24680
Motivation
----------
The Spring MVC ModelAttributeMethodProcessor includes many helpful
extension methods that allow developers to extend and enhance the data
binding capabilities of the class. Unfortunately, Spring WebFlux's
equivalent class, the ModelAttributeMethodArgumentResolver, does not
include these same extension methods. I am leveraging these extension
methods, specifically the bindRequestParameters method, to provide
valuable enhancements to my application. I would like to provide these
same enhancements to the WebFlux portion of my application and am
unable to do so at this time. I would like to update the WebFlux
ModelAttributeMethodArgumentResolver to add the bindRequestParameters
method.
Modifications
-------------
I created a new method called bindRequestParameters and encapsulated
the WebExchangeDataBinder bind call inside of it. This method is
marked as protected as it should only be used by children of this
class. This change mirrors the behavior in the equivalent Spring MVC
class (ModelAttributeMethodProcessor).
Result
------
The WebFlux ModelAttributeMethodArgumentResolver can now accept
alternative data binding implementations mirroring the Web MVC
behavior.
This commit changes the way RouterFunctions registered to the builder
are composed in both WebFlux.fn and WebMvc.fn.
Prior to this commit, all routes added to the build were composed with
`reduce`.
After this commit, all routes are stored in a special router function,
allowing for more efficient execution and smaller stack traces.
Closes gh-24652
This commit changes the way two RouterFunctions are composed in
WebFlux.fn. Prior to this commit, two were composed with
`switchIfEmpty()`, switching from the first to the second route if the
first did not provide an element.
After this commit, two router functions are compose using `concat`,
which results in a smaller stack trace.
See gh-24652
This commit adds the checkNotModified method to ServerRequest in both
WebFlux.fn and WebMvc.fn. Unlike other checkNotModified methods found
in the framework, this method does not return a boolean, but rather
a response wrapped in a Mono/Optional. If the resource has
not been changed, the not-modified response can be returned directly;
if the resource has changed, the user can create a corresponding
response using switchIfEmpty/orElse(Get).
Closes gh-24173
The attribute was previously removed only before exception resolution
in the DispatcherServlet in order to allow error rendering to make an
independent choice on content negotation.
However, Boot rendering happens later in an ERROR dispatch which could
also be a nested dispatch on some servers. So the attribute must also
generally be removed prior to mapping.
We also move the methods where this is done to the base
RequestMappingInfoHandlerMapping class which also deals with the
produces condition and where the producible attribute is added in the
first place.
Closes gh-24466
Even thought Tomcat and Jetty, which commit the response more lazily,
were not impacted by this issue, it still makes sense for them to
complete the WebFlux response (and pre-commit actions) at the same time
as for other servers for consistent behavior.
See gh-24475
Prior to this commit, some WebSocket `RequestUpgradeStrategy` reactive
implementations would prevent the application from writing HTTP headers
and cookies to the response.
For Reactor Netty and Undertow, handling the upgrade and starting the
WebSocket communication marks the response status and headers as sent
and the application cannot update HTTP response headers after that.
This commit ensures that the `RequestUpgradeStrategy` implementations
mark the responses as "complete", so that headers are written before we
delegate to the server implementation.
Fixes gh-24475
This commit updates CORS support in order to check Origin header
in CorsUtils#isPreFlightRequest which does not change how Spring
MVC or WebFlux process CORS request but is more correct in term
of behavior since it is a public API potentially used in another
contexts.
It also removes an unnecessary check in
AbstractHandlerMethodMapping#hasCorsConfigurationSource and processes
every preflight request with PreFlightHandler.
Closes gh-24327
When a request is mapped through a producible condition on an
@RequestMapping, then a failure to find a converter/decoder should be
a 500 because the return type + media type pair were declared by the
controller and that should be possible to render.
Closes gh-23287
Prior to this commit, when WebFlux handlers added `"Content-*"` response
headers and an error happened while handling the request, all those
headers would not be cleared from the response before error handling.
This commit clears those headers from the response in two places:
* when invoking the handler and adapting the response
* when writing the response body
Not removing those headers might break HTTP clients since they're given
wrong information about how to interpret the HTTP response body: the
error response body might be very different from the original one.
Fixes gh-24238
Prior to this commit, WebFlux application would keep the quality
parameter from the "Accept" request header when selecting a media type
for the response. It would then echo it back to the client.
While strictly not wrong, this is unnecessary and can confuse HTTP
clients. This commit aligns WebFlux's behavior with Spring MVC.
Fixes gh-24239
Using Consumer<ClientCodecConfigurer> instead of
Consumer<ExchangeStrategies> eliminates one level of nesting that is
also unnecessary since codecs are the only strategy at present.

The new register methods replace the now deprecated
encoder, decoder, reader, and writer methods, and also offer a choice

Prior to this commit, developers could configure their WebClient to use
their custom `ExchangeStrategies`, by providing it in the
`WebClient.Builder` chain.
Once created, an `ExchangeStrategies` instance is not mutable, which
makes it hard for further customizations by other components. In the
case of the reported issue, other components would override the default
configuration for the codecs maxInMemorySize.
This commit makes the `ExchangeStrategies` mutable and uses that fact to
further customize them with a new `WebClient.Builder#exchangeStrategies`
`Consumer` variant. This commit is also deprecating those mutating
variants in favor of a new `WebClient.Builder#exchangeStrategies` that
takes a `ExchangeStrategies#Builder` directly and avoids mutation issues
altogether.

This commit refines Coroutines annotated controller support

for that use case.

Previously, spring-webmvc and spring-webflux both contained tests
that would create gzipped files, write them to the filesystem
alongside the project's compiled test classes, and configure them to
be deleted on JVM exit. The output location placed the files on the
classpath, polluting it for every subsequent test that used the same
ClassLoader. The test-sources plugin combined with Gradle's use of
worker JVMs, broadens the scope of this pollution to other, downstream
projects in the same build. For example, the tests for
spring-websocket will have a different classpath depending on whether
or not the tests for spring-webmvc have already been run on the same
worker as part of the current build.
This commit updates the spring-webmvc and spring-webflux modules to
introduce a new JUnit Jupiter extension, GzipSupport. This extension
allows gzipped files to be created via an injectable GzippedFiles
class and automatically deletes each created file in an after-each
callback. This ensures that a gzipped file only exists on the
classpath for the duration of the test that needs it, avoiding the
pollution of the classpath of any subsequent tests.
Closes gh-23970
Previously, the infrastructure provided by WebMvcConfigurationSupport
and WebFluxConfigurationSupport can lead to unexpected results due to
the lack of qualifier for certain dependencies. Those configuration
classes refer to very specific beans, yet their injection points do not
define such qualifiers. As a result, if a candidate exists for the
requested type, the context will inject the existing bean and will
ignore a most specific one as such constraint it not defined. This can
be easily reproduced by having a primary Validator whereas a dedicated
"mvcValidator" is expected. Note that a parameter name is in no way a
constraint as the name is only used as a fallback when a single
candidate cannot be determined.
This commit provides explicit @Qualifier metadata for such injection
points, renaming the parameter name in the process to clarify that it
isn't relevant for the proper bean to be resolved by the context.
Closes gh-23887
When built in an environment where many Gradle build workers are
available, :spring-webflux:test is regularly the only task running at
the end of the build. Therefore, the build's overall execution time
can be reduced by running its tests in parallel, spreading the tests'
execution across the available workers. The configured number of forks
is a maximum with Gradle reducing this as necessary for environments
with low numbers of cores where multiple workers will not improve
build performance.
Closes gh-23701
Prior to this commit, the parameterized DataBufferFactory was never
actually used when setting up the WebClient for each test. This was due
to an oversight when migrating from JUnit 4 to JUnit Jupiter.
See: https://github.com/reactor/reactor-netty/issues/860
This commit fixes this by converting the existing @BeforeEach method to
a local setup method that is invoked from each
@ParameterizedDataBufferAllocatingTest method.
In addition, in order to avoid the 2 second "quiet period" that is
incurred when destroying the ReactorResourceFactory, this commit moves
the setup and destruction of the ReactorResourceFactory to new
@BeforeAll and @AfterAll methods.
The test instance lifecycle has also been switched to PER_CLASS to avoid
static state in the test class.
This commit reverts b2704e1db6 and
configures the ReactorResourceFactory not to use global resources,
thereby allowing all tests in WebClientDataBufferAllocatingTests to
execute within approximately 2 seconds again on Mac OS.
Prior to this commit, Spring Framework would use `Schedulers.elastic()`
in places where we needed to process blocking tasks in a reactive
environment.
With reactor/reactor-core#1804, a new `Schedulers.boundedElastic()`
scheduler is available and achieves the same goal with added security;
it guarantees that resources are bounded.
This commit uses that new scheduler in the standard websocket client,
since the underlying API is blocking for the connection phase and we
need to schedule that off a web server thread.

Prior to this commit, the isSimpleProperty() and isSimpleValueType()
methods in BeanUtils treated void and Void as simple types; however,
doing so does not make sense in this context, since void implies the
lack of a property or value.
This commit addresses this by explicitly excluding void and Void in the
logic in isSimpleValueType().
This commit also simplifies the implementation of
ViewResolutionResultHandler.supports(HandlerResult) to take advantage
of this change.
Closes gh-23573
Prior to this commit, ClassUtils.isPrimitiveOrWrapper() and
ClassUtils.isPrimitiveWrapper() did not return true for Void.class.
However, ClassUtils.isPrimitiveOrWrapper() did return true for
void.class. This lacking symmetry is inconsistent and can lead to bugs
in reflective code.
See: https://github.com/spring-projects/spring-data-r2dbc/issues/159
This commit addresses this by adding an entry for Void.class -> void.class
in the internal primitiveWrapperTypeMap in ClassUtils.

Prior to this commit, the Spring Framework build would partially use the
dependency management plugin to import and enforce BOMs.
This commit applies the dependency management plugin to all Java
projects and regroups all version management declaration in the root
`build.gradle` file (versions and exclusions).
Some versions are overridden in specific modules for
backwards-compatibility reasons or extended support.
This commit also adds the Gradle versions plugin that checks for
dependency upgrades in artifact repositories and produces a report; you
can use the following:
./gradlew dependencyUpdates
This commit makes sure that reading is enabled after the current
signal has been processed, not while is is being processed. The bug
was only apparent while using the JettyClientHttpConnector, which
requests new elements continuously, even after the end of the
stream has been signalled.
This commit prepends "[{index}] " to all custom display names
configured via @ParameterizedTest.
This provides better diagnostics between the "technical names" reported
on the CI server vs. the "display names" reported within a developer's
IDE.

Prior to this commit, the Spring Framework build would mix proper
framework modules (spring-* modules published to maven central) and
internal modules such as:
* "spring-framework-bom" (which publishes the Framework BOM with all
modules)
* "spring-core-coroutines" which is an internal modules for Kotlin
compilation only
This commit renames these modules so that they don't start with
"spring-*"; we're also moving the "kotlin-coroutines" module under
"spring-core", since it's merged in the resulting JAR.
See gh-23282
Previously DefaultWebClientBuilder always defaulted the ClientHttpConnector
with ReactorClientHttpConnector. This worked fine if reactor was used.
However, it would break if the user was trying to leverage Jetty.
This commit defaults to use Reactory Netty HttpClient if it is present. If
it is not present it then Jetty's HttpClient is used if present.
Closes gh-23491
This commit reorganizes tasks and scripts in the build to only apply
them where they're needed. We're considering here 3 "types" of projects
in our build:
* the root project, handling documentation, publishing, etc
* framework modules (a project that's published as a spring artifact)
* internal modules, such as the BOM, our coroutines support and our
integration-tests
With this change, we're strealining the project configuration for all
spring modules and only applying plugins when needed (typically our
kotlin support).

This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class
See gh-23451
This commit migrates parameterized tests in spring-core using the
"composed @ParameterizedTest" approach. This approach is reused in
follow-up commits for the migration of the remaining modules.
For a concrete example, see AbstractDataBufferAllocatingTests and its
subclasses (e.g., DataBufferTests).
Specifically, AbstractDataBufferAllocatingTests declares a custom
@ParameterizedDataBufferAllocatingTest annotation that is
meta-annotated with @ParameterizedTest and
@MethodSource("org.springframework.core.io.buffer.AbstractDataBufferAllocatingTests#dataBufferFactories()").
Individual methods in concrete subclasses are then annotated with
@ParameterizedDataBufferAllocatingTest instead of @ParameterizedTest or
@Test.
The approach makes the migration from JUnit 4 to JUnit Jupiter rather
straightforward; however, there is one major downside. The arguments
for a @ParameterizedTest test method can only be accessed by the test
method itself. It is not possible to access them in an @BeforeEach
method (see https://github.com/junit-team/junit5/issues/944).
Consequently, we are forced to declare the parameters in each such
method and delegate to a custom "setup" method. Although this is a bit
cumbersome, I feel it is currently the best way to achieve fine grained
parameterized tests within our test suite without implementing a custom
TestTemplateInvocationContextProvider for each specific use case.
Once https://github.com/junit-team/junit5/issues/878 is resolved, we
should consider migrating to parameterized test classes.

Prior to this commit, the SimpleUrlHandlerMapping classes in Spring MVC
and Spring Webflux only had default constructors. This lead to the fact
that users often had to explicitly invoke setUrlMap() and setOrder() on
the newly instantiated SimpleUrlHandlerMapping.
In order to simplify the programmatic setup of a SimpleUrlHandlerMapping
in common scenarios, this commit introduces the following constructors.
- SimpleUrlHandlerMapping()
- SimpleUrlHandlerMapping(Map<String, ?> urlMap)
- SimpleUrlHandlerMapping(Map<String, ?> urlMap, int order)
