我们正在使用的游戏应用程序必须始终保持活动状态。这个应用程序基本上是一个 RabbitMQ 监听器，它有一个无限的 while 循环，它不断地监听从消息队列中捕获消息。

以下代码放在控制器中，并且这个播放应用程序必须始终保持活动状态

公共类应用程序扩展控制器{

public static Result wanHLPT() {
    ckmsg()
    return ok();
}

public static Result ckmsg() {

    try{
    ConnectionFactory factory = new ConnectionFactory();
    factory.setHost("localhost");
    Connection connection = factory.newConnection();
    Channel channel = connection.createChannel();

    channel.queueDeclare(QUEUE_NAME, false, false, false, null);

    while (true) {
    QueueingConsumer.Delivery delivery = consumer.nextDelivery();
    String message = new String(delivery.getBody());
    // business logic
    process()

}
}
}

}

但是播放应用程序抛出akka异常[AskTimeOut异常：超时]，请提供有关如何处理的任何指示。

这是一个例外：
