When in state DATA_AVAILABLE if there are simultaneous invocations of
AbstractRequestBodyPublisher.RequestBodySubscription.request and
ReadListener.onDataAvailable, the first one will process the available
data, the second one should not throw an exception because thus it will
signal to web container that there are problems while there are not.
Refactored Undertow support to register a response listener only when
the body is written to, as opposed to registering it at startup. The
reason for this is that getting the response channel from the
HttpServerExchange commits the status and response, making it impossible
to change them after the fact.
Fixed issue #119.
When there are simultaneous invocations of onWritePossible, only the
first one should succeed. This can happens when
AbstractResponseBodySubscriber.onNext and
WriteListener.onWritePossible() are called respectively by the
application and the web container.
Reactored Servlet 3.1 and Undertow request support
(AbstractResponseBodySubscriber) to use an internal state machine,
making thread-safity a lot easier.
Currently ResponseEntityResultHandler is ordered lower than
ResponseBodyResultHandler by default whch means a ResponseEntity
should not be picked by the ResponseBodyResultHandler.
However as it is easy to have both ResponseEntity and @ResponseBody
e.g. in @RestControler (or even by mistake) and in general it makes
sense for ResponseBodyResultHandler to explicitly recognize and
ignore the ResponseEntity return type.
Before this commit only ResponseEntity with async body was supported,
e.g. ResponseEntity<Mono<String>>
This commit also adds suppport for an asyn wrapper around,
e.g. Mono<ResponseEntity<String>.
Introduce separate test classes for each base class in the hierarchy
above @ResponseBody and ResponseEntity result handlers.
Also start porting existing unit test cases for @ResponseBody and
ResponseEntity return value handlers.
Reactored Servlet 3.1 and Undertow response support into an
AbstractResponseBodySubscriber that uses an internal state machine,
making thread-safity a lot easier.
Flux<SseEvent> is Spring Web Reactive equivalent to Spring MVC
SseEmitter type. It allows to send Server-Sent Events in a reactive way.
Sending Flux<String> or Flux<Pojo> is equivalent to sending
Flux<SseEvent> with the data property set to the String or
Pojo value. For example:
@RestController
public class SseController {
@RequestMapping("/sse/string")
Flux<String> string() {
return Flux.interval(Duration.ofSeconds(1)).map(l -> "foo " + l);
}
@RequestMapping("/sse/person")
Flux<Person> person() {
return Flux.interval(Duration.ofSeconds(1)).map(l -> new Person(Long.toString(l), "foo", "bar"));
}
@RequestMapping("/sse-raw")
Flux<SseEvent> sse() {
return Flux.interval(Duration.ofSeconds(1)).map(l -> {
SseEvent event = new SseEvent();
event.setId(Long.toString(l));
event.setData("foo\nbar");
event.setComment("bar\nbaz");
return event;
});
}
}
This commit also fixes an issue in the HTTP client that used the
wrapper type instead of the element type. As a consequence, due
to type erasure, we now have to specify the type of the content
in DefaultHttpRequestBuilder#contentStream().
Renamed getSupportedMimeTypes() to getEncodableMimeTypes and
getDecodableMimeTypes. This will allow for both Encoder and Decoder to
be implemented in the same class.
This issue fixes#113.
The Pojo test class from the codec package will end up in spring-core.
This commit ensures it is used only from classes that also belong to
spring-core.
