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.
After the fix for ReactiveX/RxNetty#509 we can remove the workaround
to concatenate with an empty Observable for the request body and
upgrade to the latest RxJava 1.1.5.
Issues: #103
