How can I get the name of an Akka actor from withi

问题:

So, if I have an actor, I can give it a name. But, can I access that name internally? Example:

class Actorz extends Actor with ActorLogging {
   val actorName = //??What function

   def receive = {
     case x => log.debug(actorName+": Received Message: "+x)
   }
}

val actor = system.actorOf(Props[Actorz], "named")
actor ! "dogs"

Now, I can pass its name as a constructor parameter. But, that seems like unnecessary duplication if there is a way to get the name internally... as it was set when I instantiated the actor using system.actorOf. API docs didn't seem to have anything.

From an Actor you can use self to get the ActorRef.

val actorName = self.path.name
