更新播放2.0.2 - 地址已經與akka遠程演員一起使用

Question

我正在更新我的應用程序以播放2.0.2。

[error] play - Cannot invoke the action, eventually got an error: Thrown(akka.pattern.AskTimeoutException: Timed out) 

當調用應用程序啓動下面的代碼：

我部署阿卡遠程演員時，有一個問題

ActorSystem system = Akka.system(); 

Address addr = new Address("akka", "application"); 
defaultInstance = system.actorOf(new Props(TheActor.class).withDeploy(new Deploy(new RemoteScope(addr))), "theActor"); 

當此配置在application.conf：

akka { 
    actor { 
    provider = "akka.remote.RemoteActorRefProvider" 
    } 
    remote { 
    transport = "akka.remote.netty.NettyRemoteTransport" 
    netty { 
     hostname = "127.0.0.1" 
     port = 2552 
    } 
} 
} 

相同的設置在play-2.0.1上正常工作。

play-2.0.2的工作是否有一些配置更改？

謝謝。

Answer 1

也許試試這個：從akka documentation，可以將端口設置爲0，使用自動選擇一個：創建一個使用`concurrent.Akka.future`承諾的時候，這裏

akka { 
    actor { 
    provider = "akka.remote.RemoteActorRefProvider" 
    } 
    remote { 
    transport = "akka.remote.netty.NettyRemoteTransport" 
    netty { 
     hostname = "127.0.0.1" 
     port = 0 
    } 
} 
}
