我正在将我的应用程序更新为 play-2.0.2。

部署 Akka 远程参与者时遇到问题：

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

在应用程序启动时调用以下代码时：

ActorSystem system = Akka.system();

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

在 application.conf 中进行此配置时：

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

相同的设置在 play-2.0.1 上运行良好。

在 play-2.0.2 上是否有一些配置更改？

谢谢你。

也许试试这个：从akka 文档中，您可以将端口设置为 0 以使用自动选择的端口：

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