在Akka中实现计时器

import akka.actor.{Actor, ActorSystem, Props}
import scala.concurrent.duration._

// 定义计时器消息
case object TimerMessage

// 定义Actor类
class TimerActor extends Actor {
  // 在构造函数中使用Scheduler调度计时器事件
  val scheduler = context.system.scheduler
  val timer = scheduler.schedule(0.seconds, 1.second, self, TimerMessage)(context.dispatcher)

  // 实现接收计时器消息的逻辑
  def receive: Receive = {
    case TimerMessage =>
      // 执行计时器事件的操作
      println("Timer event occurred!")
  }
}

// 创建ActorSystem并启动Actor
val system = ActorSystem("TimerSystem")
val timerActor = system.actorOf(Props[TimerActor], "timerActor")

// 停止ActorSystem
system.terminate()
