Prior to this issue, SPR-15920 added this new `close()` method which was
supposed to be called to clean resources after response processing.
This commit changes the meaning of that method: calling `close()` will
close the underlying HTTP connection. This has to be called if the
response body is not consumed by the application, since at that point
the underlying connection might be in an inconsistent state if shared in
a connection pool.
Issue: SPR-15993
This commit moves WebFluxUriComponentsBuilder.fromServerRequest to the
ServerRequest interface itself.
Consequently, the WebFluxUriComponentsBuilder is removes itself, as it
contained no other methods.
Issue: SPR-15953
The typical way to load DispatcherHandler is to use
WebHttpHandlerBuilder#applicationContext which also detecs filters,
exception handlers, as well as other beans that are injected into every
ServerWebExchange -- custom session manager, localecontext resolver,
codecs for form data, multipart data, etc
WebHttpHandlerBuilder is the preferred and way so removing the ones on
DispatcherHandler. They could always be added back later.
This commit introduces a visitor for router functions
(RouterFunctions.Visitor), allowing to iterate over all the components
that make up a router function.
This commit also introduces a ToStringVisitor, which creates a nicely
formatted string for use with toString().
Issue: SPR-15711, SPR-15711
This commit introduces the WebFluxUriComponentsBuilder, with a single
method that creates a UriComponentsBuilder for a ServerRequest. More
methods to be added by @rstoyanchev.
Issue: SPR-15953
This commit introduces a methodName() method to the ServerRequest,
returning the String name of the method. This method is useful for
non-standard HTTP methods.
This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
Issue: SPR-15756
This commit fixes a typo in the `DefaultWebClient` implementation.
Instead of forwarding resolved `WebClientException` instances as error
signals, the `bodyToMono(ParameterizedTypeReference)` variant would just
forward those exceptions as `onNext` signals.
Issue: SPR-15946
Prior to that commit, the `ResponseSpec` `WebClient` would process error
responses (4xx, 5xx HTTP status) and transform those into error signals
with a `WebClientResponseException`. But this would only work if the
HTTP response would have a non-empty response body.
An empty error response would not send an error signal and only
translate in an `onComplete` signal.
This commit fixes this behavior and makes sure that this error signal is
sent in all cases.
Issue: SPR-15946
Before this commit, there was no way to signal the HTTP client that we
were done consuming the response. Without that, the underlying client
library cannot know when it is safe to release the associated resources
(e.g. the HTTP connection).
This commit adds new `close()` methods on both `ClientHttpResponse`
and `ClientResponse`. This methods is non-blocking and its behavior
depends on the library, its configuration, HTTP version, etc.
At the `WebClient` level, `close()` is called automatically if we
consume the response body through the `ResponseSpec` or the
`ClientResponse` itself.
Note that it is *required* to call `close()` manually otherwise; not
doing so might create resource leaks or connection issues.
Issue: SPR-15920
This commit moves `encodeUrl` and `registerUrlEncoder` from
ServerHttpResponse to ServerWebExchange.
It also renames `encodeUrl` to `transformUrl` and `registerUrlEncoder`
to `addUrlTransformer` to make it clearer that these methods do not
perform actual URL encodings (i.e. they do not replaceinvalid
characters).
The `add` prefix (instead of `register`) makes it clearer that each
function is added in addition to the previous one.
Issue: SPR-15924
This commit applies the Dependency Management Plugin to modules that
require it; right now Spring Framework is importing BOMs for Netty and
Reactor dependencies only.
Instead of applying those BOMs to all modules, they're applied only
where they're needed.
Issue: SPR-15885
The main `build.gradle` file contains now only the common build
infrastructure; all module-specific build configurations have
been moved to their own build file.
