class SayHelloActor extends Actor {

    case "xf" => println("xf  hahhahah！")
    case _ => println("您是?")

  }
}

  private val actoryFactory = ActorSystem("actoryFactory")
 //创建一个Actor的同时，返回一个actor 的引用actorref
  //说明：
//Props[SayHelloActor]  使用反射创建了一个SayHelloActor 实例
//  "sayHelloActor" 给 actor 取名
//  sayHelloActorActorRef 就是 Props[SayHelloActor]  的ActorRef

  //test
  def main(args: Array[String]): Unit = {
    //给SayHelloActor 发消息
    sayHelloActorRef ! "xf"
