This commit documents the fact that default status handlers configured
on the `WebClient` are not applied to `exchangeTo*` methods as those
variants give full access to the client response.
Applying them here would restrict the ability to adapt the behavior
depending on the HTTP response status.
Closes gh-30059
Prior to this commit, an error thrown by a `ExchangeFilterFunction`
configured on a `WebClient` instance would be recorded as such by the
client observation, but the response details would be missing from the
observation.
All filter functions and the exchange function (performing the HTTP
call) would be merged into a single `ExchangeFunction`; this instance
was instrumented and osberved. As a result, the instrumentation would
only get the error signal returned by the filter function and would not
see the HTTP response even if it was received. This means that the
recorded observation would not have the relevant information for the
HTTP status.
This commit ensures that between the configured `ExchangeFilterFunction`
and the `ExchangeFunction`, an instrumentation `ExchangeFilterFunction`
is inserted. This allows to set the client response to the observation
context, even if a later error signal is thrown by a filter function.
Note that with this change, an error signal sent by a filter function
will be still recorded in the observation.

This commit updates AbstractMessageWriterResultHandler#writeBody in
order to use the declared bodyParameter instead of
ResolvableType.forInstance(body) when the former has unresolvable
generics.

This commit turns some stream-based iterations back into simpler
enhanced for loops.
For simple use cases like these, where the stream API is merely used to
map/filter + collect to a List, a for loop is more efficient.
This is especially true for small collections like the ones we deal
with in BodyInserters/BodyExtractors here (in the order of 50ns/op vs
5ns/op). These cases are also simple enough that they don't lose in
readability after the conversion.
Closes gh-30136
Prior to this commit, the `RequestedContentTypeResolverBuilder` would
create a `RequestedContentTypeResolver` that internally delegates to a
list of resolvers. Each resolver would either return the list of
requested media types, or a singleton list with the "*/*" media type; in
this case this signals that the resolver cannot find a specific media
type requested and that we should continue with the next resolver in the
list.
Media Types returned by resolvers can contain parameters, such as the
quality factor. If the HTTP client requests "*/*;q=0.8", the
`HeaderContentTypeResolver` will return this as a singleton list. While
this has been resolved from the request, such a media type should not be
selected over other media types that could be returned by other
resolvers.
This commit changes the `RequestedContentTypeResolverBuilder` so that it
does not select "*/*;q=0.8" as the requested media type, but instead
continues delegating to other resolvers in the list. This means we need
to remove the quality factor before comparing it to the "*/*" for
equality check.

This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.

HttpServiceProxyFactoryExtensions.kt has been mistakenly created
in spring-webflux module instead of spring-web, breaking JPMS for
WebFlux users.
This commit moves this file and related tests to the spring-web
module.
Closes gh-30042
This commit ensures that WebFlux's RequestMethodsRequestCondition
supports HTTP methods that are not in the RequestMethod enum.
- RequestMethod::resolve is introduced, to convert from a HttpMethod
(name) to enum values.
- RequestMethod::asHttpMethod is introduced, to convert from enum value
to HttpMethod.
- HttpMethod::valueOf replaced Map-based lookup to a switch statement
- Enabled tests that check for WebDAV methods

This commit makes several changes to PR #24651.
- Add byte[] getContentAsByteArray() on Resource.
- Remove getContentAsString() from Resource, as it relied on the default
charset which is not reliable.
- Add getContentAsString() to EncodedResource, as a charset is provided
through the constructor.

This commit introduces DataBuffer::readableByteBuffers and
DataBuffer::writableByteBuffers, allowing restricted access to the
ByteBuffer used internally by DataBuffer implementations.

Add constructors to HttpMediaTypeNotSupportedException and
UnsupportedMediaTypeStatusException for a parse error that also accept
the list of supported media types to include in the response headers.

Prior to this commit, the "uri" KeyValue for low cardinality metadata
would contain the entire uri template given to the HTTP client when
creating the request. This was a breaking change for existing metrics
dashboards, as previous support was removing the protocol, host and port
parts of the URI.
Indeed, this information is available in the "client.name" and
"http.uri" KayValue.
This commit parses and removes the protocol+host+port information from
the uri template for the "uri" KeyValue.
Fixes gh-29885
Prior to this commit, client HTTP requests performed by `WebClient`
could miss the "uri" KeyValue for simple "/" requests.
This can happen when the baseUri is configured for the client with a
host and a root base path like "https://example.org/"; given the nature
of the `WebClient` API, in these cases, one can perform requests like
this:
```
WebClient client = WebClient.builder()
.observationRegistry(registry)
.baseUrl("https://example.org/")
.build();
String response = client.get().retrieve().bodyToMono(String.class).block();
```
Such a call would contribute a `"none"` value for the `"uri"` KeyValue.
While only templates should be allowed for this keyvalue, we can assume
that requests to `"/"` should be recorded anyway and won't cause
cardinality explosion.
Fixes gh-29879
Prior to this commit, the `DefaultWebClient` would be instrumented for
client observations and would start/stop a `"http.client.requests"`
observation. This would not set this new observation as the current one
in the Reactor context under `ObservationThreadLocalAccessor.KEY`.
This means that potential child observations would not detect it as
their parent; this can happen if the Reactor Netty `HttpClient`
observation is enabled.
This commit ensures that the reactor context is properly populated for
upstream operators.
Fixes gh-29891
Prior to this commit, the `"client.name"` key value for the
`"http.client.requests"` client HTTP observations would be considered as
high cardinality, as the URI host is technically unbounded.
In practice, the number of hosts used by a client in a given application
can be considered as low cardinality. This commit moves this keyvalue to
low cardinality so that it's present for both metrics and traces.
Closes gh-29839
Prior to this commit, the reactive `ResourceWebHandler` would only look
at the path within the current mapping when resolving static resources
to be served. This means that when registering a handler at
`"/resources/**"` with a `"classpath:/static/"` location, the handler
would process a `"GET /resources/file.txt"` as the `"/static/file.txt"`
classpath location.
When a developer registers a fixed pattern like `"/resources/file.txt"`
with the same location, the path within the handler mapping is empty as
there is no dynamic part in the given pattern. While the typical use
case for this feature is to register multiple resources at once with a
pattern, we should support a single registration like this.
This commit ensures that if the matching `PathPattern` for the current
request does not have a pattern syntax (i.e. no regexp, no wildcard), we
can use it to match the resource directly. Otherwise, we can use the
path within the handler mapping to resolve the resource as before.
