> 启动程序：

package com.zxl.akka.two_actors
    
    import akka.actor.{
        ActorRef, ActorSystem, Props}
    
    //extends App 可以替代main方法
    object ActorGame extends App {
          
    
    
      //创建 ActorSystem
      val actorfactory = ActorSystem("actorfactory")
      //先创建 BActor 引用/代理
      val bActorRef: ActorRef = actorfactory.actorOf(Props[BActor], "bActor")
      //创建 AActor 的引用
      val aActorRef: ActorRef = actorfactory.actorOf(Props(new AActor(bActorRef)), "aActor")
      //aActor 出招
      aActorRef ! "start"
    
    }

> AActor

package com.zxl.akka.two_actors
    
    import akka.actor.{
        Actor, ActorRef}
    
    
    class AActor(actorRef: ActorRef) extends Actor {
        
      val bActorRef: ActorRef = actorRef
      override def receive: Receive = {
        
        case "start" => {
        
          println("AActor 出招了 , start ok")
          self ! "我打" //发给自己
        }
        case "我打" => {
        
          //给 BActor 发出消息
          //这里需要持有 BActor 的引用(BActorRef)
          println("AActor(黄飞鸿) 厉害 看我佛山无影脚")
          Thread.sleep(1000)
          bActorRef ! "我打" //给 BActor 发出消息
        }
      }
    }

> BActor

package com.zxl.akka.two_actors
    
    import akka.actor.Actor
    
    
    class BActor extends Actor{
        
      override def receive:Receive = {
        
        case "我打" => {
        
          println("BActor(乔峰) 挺猛 看我降龙十八掌")
          Thread.sleep(1000)
          //通过 sender() 可以获取到发现消息的 actor 的 ref
          sender() ! "我打"
        }
      }
    }
