我想知道是否有可能知道何时传递邮件。因为我想稍后关闭actorsystem。下面的代码连接到远程参与者,然后发送一条消息。但是在某些情况下,本地参与者系统似乎关闭得太早了。
ActorSystem system = ActorSystem.create("Test", config.getConfig("webbackend"));
ActorSelection communicator = system.actorSelection("akka.tcp://[email protected]:2555/user/Communicator");
communicator.tell(new TimerTransmissionCmd(channel.getId()), ActorRef.noSender());
//system.shutdown();
最佳答案
发送消息后,尝试添加以下代码:
Boolean wasProcessed = (Integer)Await.result(Patterns.ask(communicator, new ResultClass(), 5000),
Duration.create(5000, TimeUnit.MILLISECONDS));
if(wasProcessed){
actorSystem.shutdown();
}
您还必须在Actor类中添加以下内容:
private boolean wasProcessed = false;
@Override
public void onReceive(Object messageReceived) throws Exception {
if (messageReceived instanceof ResultClass) {
this.workerActor1.tell(wasProcessed, getSender());
} else {
//Put your process code here
wasProcessed = true;
}
}
但是我建议您配置一个谨慎的超时,然后始终关闭系统。
