将简单的Scala远程actor示例移植到Akka actor

import akka.actor.{Actor, ActorRef, ActorSystem, Props}
import akka.remote.{AssociatedEvent, DisassociatedEvent, RemotingLifecycleEvent}

case class Message(content: String)

class MyActor extends Actor {
  override def receive: Receive = {
    case Message(content) => println(s"Received message: $content")
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val system = ActorSystem("MySystem")
    val remoteActor = system.actorOf(Props[MyActor], "remoteActor")

    system.eventStream.subscribe(system.actorOf(Props(new Actor {
      override def receive: Receive = {
        case AssociatedEvent(localAddress, remoteAddress, inbound) =>
          println(s"Associated: $localAddress $remoteAddress $inbound")
        case DisassociatedEvent(localAddress, remoteAddress, inbound) =>
          println(s"Disassociated: $localAddress $remoteAddress $inbound")
      }
    })), classOf[RemotingLifecycleEvent])

    remoteActor ! Message("Hello, remote actor!")
  }
}
