核心
1、scala中actor的操作

package com.xlucas
import sun.plugin2.jvm.RemoteJVMLauncher.CallBack

import scala.actors._
/**

  */
object ActorOop {
  def main(args: Array[String]): Unit = {

    val callback =new callBack()  //例項化 callback
    callback.start()//啟動執行緒
    val call= new
 
 call(callback) //例項化 callback
    call.start()//啟動執行緒
  }
}
case class hello(name:String,context:String,sender:Actor)
case class helloback(name:String,context:String,sender:Actor)

class call(val callBack: Actor) extends Actor{
  var count=0
  def act(): Unit ={ //重寫方法
    callBack!helloback("spark","hadoop "
 
,this) //傳送訊息
    while (true){
      receive{
        case hello(name,context,sender)=>{
          println("hello"+" name: "+name+" context:"+context+" count: "+count)
          count +=1
          sender!helloback(name,context,this)//傳送訊息
          Thread.sleep(3000)
        }
      }
    }
  }
}
class
 
 callBack extends Actor {
  var count=0
   def act(): Unit = (
    while(true){
      receive{
        case helloback(name,context,sender)=>{
          println("helloBack"+" name: "+name+" context:"+context+"  count: "+count)
          count +=1
          sender!hello(name,context,this) //傳送訊息
          Thread.sleep(3000)
        }
      }
    }
  )
}

執行結果
helloBack name: spark context:hadoop count: 0
hello name: spark context:hadoop count: 0
helloBack name: spark context:hadoop count: 1
hello name: spark context:hadoop count: 1
helloBack name: spark context:hadoop count: 2
hello name: spark context:hadoop count: 2
