Akka Typed 演员在玩 websocket

Question

I'm developing a web-socket application in play and using actor based websocket implementation according to their official tutorial ( https://www.playframework.com/documentation/2.8.x/JavaWebSockets )

In controller

 public WebSocket socket() {
    System.out.println("socket connecton received");
    return WebSocket.Text.accept(
            request -> ActorFlow.actorRef(WebSocketActor::props, actorSystem, materializer));
}

WebSocketActor is implemented with Typed actors as below

public class WebSocketActor extends AbstractBehavior<String> {

But the issue is it is giving me following error Incompatible types: ActorRef is not convertible to ActorRef and it seems like ActorFlow.actorRef is only allows un-typed actors.

How can I use a Typed Actor with above implementation.

Answer 1

When there are missing APIs for typed (I think this is the case with the Play ActorFlow) you can adapt the new typed APIs to the classic ones using akka.actor.typed.javadsl.Adapter , like so: Adapter.toClassic(typedActorRef)

More docs on coexisting typed and classic APIs here: https://doc.akka.io/docs/akka/current/typed/coexisting.html
