Can not serialize CompletionStage<Response> #5103
Comments
This looks more like a Yasson issue. |
|
The thing is that Jersey does not handle |
|
Jsonb impl(Yasson) provides basic serialization for general purpose. But I do think it is the responsibility of Yasson. As a Jaxrs impl, to support Async using Java 8 As you mentioned, to get a list( Quarkus supports such an approach in the early version, check my example CompletableFuture, in the new version, it is replaced by RactiveStreams(Small Mutiny). In contrast to Spring, besides the async So I think to support async in Jaxrs, it should add it own serializer to handle |

I would like use @GET
@Produces(MediaType.APPLICATION_JSON)
public CompletionStage<Response> getAllPosts() {
return this.posts.findAll().thenApply(posts -> ok(posts).build());
}
@POST
@Consumes(MediaType.APPLICATION_JSON)
public CompletionStage<Response> savePost(@Valid Post post/*, @Context UriInfo uriInfo*/) {
//uriInfo.getBaseUriBuilder().path("/posts/{id}").build(id.toString())
return this.posts.save(post).thenApply(id -> created(URI.create("/posts/" + id.toString())).build());
}
@Path("{id}")
@PUT
@Consumes(MediaType.APPLICATION_JSON)
public CompletionStage<Response> updatePost(@PathParam("id") final String id, @Valid Post post) {
return this.posts.update(UUID.fromString(id), post)
.thenApply(updated -> updated > 0 ? Status.NO_CONTENT : Status.NOT_FOUND)
.thenApply(status -> status(status).build());
}
@Path("{id}")
@GET
@Produces(MediaType.APPLICATION_JSON)
public CompletionStage<Response> getPostById(@PathParam("id") final String id) {
return this.posts.findById(UUID.fromString(id))
.thenApply(post -> ok(post).build())
.exceptionally(throwable -> {
LOGGER.log(Level.WARNING, " failed to get post by id :", throwable);
return status(NOT_FOUND).build();
});
}
@DELETE
@Path("{id}")
public CompletionStage<Response> delete(@PathParam("id") String id) {
return this.posts.delete(id)
.thenApply(deleted -> deleted > 0 ? Status.NO_CONTENT : Status.NOT_FOUND)
.thenApply(status -> status(status).build());
}And we are moving to Java 11, Java 9 Flow(and ReactiveStreams, there are some utility available to convert from/to Java 9 Flow) |
