This commit extracts the response body insertion logic into a separate
strategy interface: BodyPopulator. Standard populators can be found in
BodyPopulators.
This commit refactors the Router into a RoutingFunctions class, by:
- Renaming the class :)
- Moving all Configuration logic into a separate, top-level
Configuration class with mutable builder.
Since appcache manifests can have various file extensions, developers
should register the (file extension, media type) mapping in their Spring
MVC / Reactive Web configuration.
This commit adds javadoc on both `AppCacheManifestTransformer` variants
to explain how to do that.
Issue: SPR-14510
This commit changes the default file extension configured with
`AppCacheManifestTranformer`. This ResourceTransformer was previously
considering `.manifest` files by default, but this has been changed in
the official spec to `appcache`, in order not to clash with Microsoft's
unregistered application/manifest type.

`ResolvedResource` is a rather generic name - changing the extended
interface to something more meaningful: `HttpResource`.
For now, implementations are linked with the resource handling chain,
but this aspect has been removed from the interface documentation.

Prior to this commit, FreeMarkerView used the system default charset to
render. This commit switches this by defaulting to UTF-8, if no charset
is specified in the content type.
- Add contentType parameter to AbstractView.renderInternal, used to
determine the charset contained therein
- Adds a defaultCharset property to AbstractView and
ViewResolverSupport.
Changed View's render method from taking a HandlerResult to taking a
Map<String, ?>, in order to facilitate scenarios where a HandlerResult
is not available (i.e. web.reactive.function).
Two changes to web.reactive.function:
- Changed Response.stream method to allow for specific Publisher types
to be returned in Response.
- Router now stores HttpMessageReader|Writer retrieved from
Configuration in the attributes as supplier, not as stream, to allow
for multiple reads.
Prior to this commit, the resource handling chain and its
`ResourceResolvers` would use specific `Resource` implementations in
order to add resource metadata to the HTTP response. For example,
`VersionedResource` and `EncodedResource` are both adding specific HTTP
response headers.
This commit aims at making this mechanism more stable and reusable,
since the previous implementation would fail in case a resolved resource
would be both a `VersionedResource` wrapping a `EncodedResource` (or the
other way arount). Only one of the specific implementations would
contribute its metadata since the code supporting that in
`ResourceHttpRequestHandler` would only check for `instanceof` tests,
whereas those implementations are acutally delegating calls to
the wrapped resource.
Now both `VersionedResource` and `EncodedResource` have been replaced by
specific implementations of `ResolvedResource`, which directly provides
those HTTP response headers as part of `getResponseHeaders()`.
This commit applies the same changes for the web reactive
implementations and its `ResourceWebHandler`.
Issue: SPR-14264
A straight-forward port of the resource handling support in
spring-webmvc to spring-web-reactive. Primarily adapting contracts and
implementations to use the reactive request and response and the
reactive ResourceHttpMessageWriter.
Issue: SPR-14521
This commit fixes `ResponseEntityResultHandler` so that it only tries to
call `writeBody` if the `ResponseEntity` is not null. In case the
response entity body is null, the response is flushed right away and the
request is signaled as handled.
Issue: SPR-14663
This change puts the MockHttpServerRequest/Response under
org.springframework.mock.http.server.reactive.test which
mirrors the arrangement we have with the Servlet mock equivalents
and sets up the addition of MockHttpServerRequest/Response in
spring-test.
Issue: SPR-14421
This commit introduces a new, functional web programming model in the
org.springframework.web.reactive.function package. The key types
are:
- Request and Response are new Java 8-DSLs for access to the HTTP
request and response
- HandlerFunction represents a function to handle a request to a
response
- RoutingFunction maps a request to a HandlerFunction
- FilterFunction filters a routing as defined by a RoutingFunction
- RequestPredicate is used by Router to create RoutingFunctions
- RequestPredicates offers common RequestPredicate instances
- Renamed SseEvent to ServerSentEvent to make the name less redundant.
- ServerSentEvent is now immutable, having a builder to create new instances.
- Realigned the class properties to more closely match the events
described in the spec, so that `reconnectTime` becomes `retry`, and
`name` becomes `event`.
This commit updates the instructions on getting started with
Spring Web Reactive and also updates constructors and setters to
streamline the getting started procedure.
Issue: SPR-14640
Prior to this commit, exceptions thrown by the
`HandlerMethodArgumentResolver` would be wrapped into
`IllegalStateException`s.
This commit makes sure that a DEBUG log is written with the relevant
information and that the root cause is not wrapped into another
exception, so that the appropriate `ExceptionHandler` can be used to
deal with this error.
Issue: SPR-14618
reactor.test.TestSubscriber will not be part of Reactor Core
3.0.0 since it needs to be refactored to fit all the needs
expressed by the users. It is likely to be back later in one
of the Reactor Core 3.0.x releases.
This commit anticipate this removal by temporarily copying
TestSubscriber in spring-core test classes. As soon as
the new TestSubscriber will be available in Reactor Core,
Spring Framework reactive tests will use it again.
