Scala并发编程【消息机制】

1.入门

 package actor

 import scala.actors.Actor
 import scala.actors.migration.ActorDSL

 /**
   * Created by zhen on 2018/11/7.
   */
 class OldActor extends Actor{
   def act(): Unit = {
     println("scala2.10之前版本")
     for(i <-1 to 2){
       println("step:"+i)
       Thread.sleep(1000)
     }
   }
 }
 object ActorDemo{
   def main(args: Array[String]) {
     //老版本Actor
     val oldActor = new OldActor()
     oldActor.act()
     val actor = ActorDSL.actor(new Actor {
       override def act(): Unit = {
         println("scala2.10之后版本使用Akka机制")
         for(i <-1 to 2){
           println("step:"+i)
           Thread.sleep(1000)
         }
       }
     })
   }
 }

结果：

2.发送消息

 // 发送消息
     val actorMessage = ActorDSL.actor(new Actor {
       override def act(): Unit = {
         while(true){
           receive{
             case data : Int => println("age is : " + data)
             case  _ => println("something unknown !")
           }
         }
       }
     })
     actorMessage ! 18
     actorMessage ! "hello everyone !"

结果：
