如何从演员本身中获取 Akka 演员的姓名? [英] How can I get the name of an Akka actor from within the actor itself?

问题描述

所以，如果我有演员，我可以给它起个名字.但是，我可以在内部访问该名称吗?示例:

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"

现在，我可以将其名称作为构造函数参数传递.但是，如果有办法在内部获取名称，这似乎是不必要的重复......因为它是在我使用 system.actorOf 实例化 actor 时设置的.API 文档似乎没有任何内容.

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.

推荐答案

从 Actor 您可以使用 self 来获取 ActorRef.

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

val actorName = self.path.name
