Scala消息机制Actor(旧版及新版Akka)

1.入门

 1 package actor
 2 
 3 import scala.actors.Actor
 4 import scala.actors.migration.ActorDSL
 5 
 6 /**

 9 class OldActor extends Actor{
10   def act(): Unit = {
11     println("scala2.10之前版本")
12     for(i <-1 to 2){
13       println("step:"+i)
14       Thread.sleep(1000)
15     }
16   }
17 }
18 object ActorDemo{
19   def main(args: Array[String]) {
20     //老版本Actor
21     val oldActor = new OldActor()
22     oldActor.act()
23     val actor = ActorDSL.actor(new Actor {
24       override def act(): Unit = {
25         println("scala2.10之后版本使用Akka机制")
26         for(i <-1 to 2){
27           println("step:"+i)
28           Thread.sleep(1000)
29         }
30       }
31     })
32   }
33 }

结果：

2.发送消息

 1 // 发送消息
 2     val actorMessage = ActorDSL.actor(new Actor {
 3       override def act(): Unit = {
 4         while(true){
 5           receive{
 6             case data : Int => println("age is : " + data)
 7             case  _ => println("something unknown !")
 8           }
 9         }
10       }
11     })
12     actorMessage ! 18
13     actorMessage ! "hello everyone !"

结果：
