I'm familiar with Apache CXF to build REST services. I implemented some
Akka service which I want to expose via REST.
I know Akka has built akka-http but why should I use it if I can simply
implement a REST service with Appache CXF and AsyncReponse? (See example
below)
Any hint is welcome.
----- snip ----
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.HashMap;
@Path("/myService/{value}")
public class ExampleService {
@Context ActorSystem actorSystem;
LoggingAdapter log;
@GET
@Produces(MediaType.APPLICATION_JSON)
public void getExamples (@PathParam("value") Integer value, final
AsyncResponse res) {
ActorSelection serviceActor =
actorSystem.actorSelection("/user/serviceActor");
Timeout timeout = new Timeout(Duration.create(2, "seconds"));
Future<Object> future = Patterns.ask(serviceActor, value, timeout);
future.onComplete(new OnComplete<Object>() {
public void onComplete(Throwable failure, Object result) {
HashMap<String,Object> response = new
HashMap<String,Object>();
response.put("results",result);
res.resume(Response.ok().entity(response).build());
}
}, actorSystem.dispatcher());
}
}
