本文介绍了一个使用 Scala 语言实现的简单 Actor 模型示例。通过创建一个 Actor 实例并发送消息来演示 Actor 的基本工作原理。案例中定义了一个 Actor 类 ActorDemo 并实现了消息接收与处理的方法。

package com.spark.scala.basics

import scala.actors.Actor

/**
  * 1.
  */
object ActorDemo {
  def main(args: Array[String]): Unit = {
    val actorDemo = new ActorDemo
    actorDemo.start()

    var count = 0
/*    while (true) {
      actorDemo ! " is " + count
      count += 1
      Thread.sleep(10)
    }*/
    actorDemo ! Hello("Spark", "Spark is very good!")

  }
}

case class Hello(name: String, content: String)
case class HelloBack(name: String, content: String)

class ActorDemo extends Actor {
  def act(): Unit = {
    while (true) {
      receive {
        case content: String => println("Message " + content)
        case Hello(name, content) => println("name is " + name + ", content is " + content + ".")
      }
    }
  }
}
