Akka远程处理 - 无法分配请求的地址

Question

我想尝试一个Akka-Remoting的例子。每次我开始我的远程演员系统我得到这个异常

这是我 application.conf细节

remoteCalculator{ 
    akka { 
    actor { 
    provider = "akka.remote.RemoteActorRefProvider" 
    } 
    remote { 
    transport = "akka.remote.netty.NettyRemoteTransport" 
    log-received-messages = on 
    log-sent-messages = on 
    log-remote-lifecycle-events = on 
    enabled-transports = ["akka.remote.netty.tcp"] 
    netty.tcp { 
     hostname = "10.147.137.44" 
     port = 2555 
     log-received-messages = on 
     log-sent-messages = on 
     log-remote-lifecycle-events = on 
    } 
    } 
    } 
} 

我试图找到另一个应用程序通过执行侦听的端口2555的可能性以下命令

sudo netstat -anp | grep 2555 

但它没有给出任何东西。请帮我找出应用程序无法绑定到配置地址的原因。

Answer 1

我得到了问题的根源。其实这不是一个配置/ proramming问题。我正在使用我的窗口操作系统内的虚拟主机（Ubuntu），但我没有启用网络桥接器。因此，虚拟主机无法识别主机名。启用网桥后，问题得到解决。
