如何从Akka中的非演员获取对现有演员的引用？

Question

In my application, I have a class which needs to communicate with an existing actor already created in an actorSystem. How do I get a reference to that actor from this non-actor class?

Answer 1

If you have the reference to the actor system ( https://doc.akka.io/api/akka/current/akka/actor/ActorSystem.html ), then you can simply invoke actorSelection with the path of the actor. This will give you an ActorSelection , on which you can call resolveOne , and then wait until you get the reference of the actor. Once you have the actor reference, you can send messages to it.
