Akka 编程：从 Actor 操作到并发编程的全面解析

1. 发送 Kill 消息示例

以下代码展示了如何向 Actor 发送 Kill 消息：

override def postStop { println("Number5::postStop called") }
override def preRestart(reason: Throwable, message: Option[Any]) {
  println("Number5::preRestart called")
}
override def postRestart(reason: Throwable) {
  println("Number5::postRestart called")
}
}
object KillTest extends App {
  val system = ActorSystem("KillTestSystem")
  val number5 = system.actorOf(Props[Number5], name = "Number5")
  number5 ! "hello"
  // send the Kill message
  number5 ! Kill
  system.shutdown
}

运行上述代码，输出如下：

Number5 is alive
Number5 got a message
[ERROR] [16:57:02.220] [KillTestSystem-akka.actor.default-dispatcher-
