啟動程序：

package com.zxl.akka.two_actorsimport akka.actor.{ActorRef, ActorSystem, Props}//extends App 可以替代main方法 object ActorGame extends App { //創建 ActorSystemval actorfactory = ActorSystem("actorfactory")//先創建 BActor 引用/代理val bActorRef: ActorRef = actorfactory.actorOf(Props[BActor], "bActor")//創建 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_actorsimport akka.actor.{Actor, ActorRef}class AActor(actorRef: ActorRef) extends Actor {val bActorRef: ActorRef = actorRefoverride def receive: Receive = {case "start" => {println("AActor 出招了 , start ok")self ! "我打" //發給自己}case "我打" => {//給 BActor 發出消息//這里需要持有 BActor 的引用(BActorRef)println("AActor(黃飛鴻) 厲害 看我佛山無影腳")Thread.sleep(1000)bActorRef ! "我打" //給 BActor 發出消息}} }

BActor

package com.zxl.akka.two_actorsimport akka.actor.Actorclass BActor extends Actor{override def receive:Receive = {case "我打" => {println("BActor(喬峰) 挺猛 看我降龍十八掌")Thread.sleep(1000)//通過 sender() 可以獲取到發現消息的 actor 的 refsender() ! "我打"}} }
