Question

在演员中我创建了一个像下面的儿童演员

ActorRef sessionEventHandlerActor = getContext().actorOf(Props.create(SessionHandler.class), sessionId);

这是SessionHandler actor：

public class SessionHandler extends UntypedActor {

    public SessionHandler() {
        getContext().setReceiveTimeout(Duration.create(1, TimeUnit.MINUTES));
    }


    @Override
    public void onReceive(Object message) throws Exception {


     }
}

我收到以下错误：

Caused by: akka.actor.ActorInitializationException: You cannot create an instance of [actors.SessionHandler] explicitly using the constructor (new). You have to use one of the 'actorOf' factory methods to create a new actor. See the documentation.

我没有看到我如何创建演员的任何问题。有人知道问题是什么吗？

谢谢

我认为已经没有问题，但我认为你需要省略sessionId参数，因为create会尝试将它应用到构造函数。

$(window).resize(function() {
  $('#slider-home .slider-session').slick('resize');
  $('#seguradoras-carrousel .slider-session').slick('resize');
});

据我所知，Java API。我只在scala中使用它。

创建子actor时出错
