Question

尝试运行mykka应用程序时出现此错误：

[ERROR] [06/30/2014 15：58：14.591] [Thread-3] [RemoteActorRefProvider] 查找地址时出错[akka：//FooPar0@127.0.0.1:2552] akka.remote.RemoteTransportException：未加载传输 protocol：[akka]，可用协议：[akka.tcp] at akka.remote.Remoting $ .localAddressFo rRemote（Remoting.scala：88） ...

我的sbt项目有以下build.sbt：

name：=＆＃34; FooPar＆＃34;

版本：=＆＃34; 0.1＆＃34;

scalaVersion：=＆＃34; 2.11.1＆＃34;

最后，我的应用程序生成的配置字符串如下所示：

akka {
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote { 
        enabled-transports = ["akka.remote.netty.tcp"]

        netty.tcp.hostname = "10.126.13.61" 
        netty.tcp.port = 2552
        netty.tcp.message-frame-size = 20 MiB
        //netty.tcp {
      //    write-buffer-high-water-mark = 148000b
          //  send-buffer-size = 148000b
           // receive-buffer-size = 148000b
        //}
  }

  event-handlers = []
  loglevel=WARNING

}    


my-custom-dispatcher {
//    type = PinnedDispatcher
    executor = thread-pool-executor
    # 10 years should be enough
//    thread-pool-executor.keep-alive-time = 315360000s
    # note that disabling core timeout altogether doesn't work
    # until ticket 2856 is fixed
    thread-pool-executor.allow-core-timeout = off
  mailbox-type = "akka.dispatch.UnboundedDequeBasedMailbox"
}

有人可以帮我找到问题吗？我在这里遵循本指南http://doc.akka.io/docs/akka/2.3.4/scala/remoting.html，但似乎我的配置文件应该是

作为对马里奥的回应：

我从上面列出的配置字符串中实例化ActorSystem，然后通过以下代码实现：

  private var system: Option[ActorSystem] = None
  def getSystem(machinefile: String) = synchronized {
    system match {
      case None =>
        system = Some(ActorSystem("FooPar" + indexOf(hostName, machinefile),
          ConfigFactory.parseString(conf))); system
      case Some(sys) => system
    }
  }

也就是说，我没有明确地创建Address个对象。

在创建akka.actor.Address的实例时，这看起来很像问题。要使远程处理工作，第一个参数必须是"akka.tcp"而不是"akka"：

val addr = Address("akka.tcp", "actorSystem", hostname, port)

然后当你想获得对演员的引用时：

val path = RootActorPath(addr) / "user" / "actorName"
val actorRef = context.actorSelection(path)

（请注意context也可能是system）

正如评论中所述，由于您正在使用actorFor，请尝试在网址中使用akka.tcp://代替akka://。

使用Scala 2.11.1在akka 2.3.4中没有为协议定位传输
