我是 akka 的新手，正在尝试让一个样本在多个 JVM 之间工作。我正在使用此处显示的示例，但遇到了问题。在下面的日志末尾，您可以看到一个 AssociationError，表示连接127.0.0.1:2552被拒绝。

如果远程处理在本地主机地址上开始，我会喜欢它，这样我在更改 IP 地址时就不必重新配置。我的application.conf包含：

akka {
    log-config-on-start = off
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    loglevel = "DEBUG"
    actor {
        provider = "akka.remote.RemoteActorRefProvider"
        debug {
            receive = on
            autoreceive = on
            lifecycle = on
            unhandled = on
        }
        deployment {
            /buffer/client {
                remote = "akka.tcp://RandomOrgSystem@127.0.0.1:2552"
            }
        }
    }
    remote {
        transport = "akka.remote.netty.NettyRemoteTransport"
        log-sent-messages = on
        netty {
            hostname = "127.0.0.1"
        }
    }
}

谢谢，汤姆

尝试将您的remote部分更改为：

remote {
    transport = "akka.remote.netty.NettyRemoteTransport"
    log-sent-messages = on
    netty.tcp {
        hostname = "127.0.0.1"
    }
}

因为配置错误并且你没有指定hostname属性，所以默认使用主机ip。如上所述设置配置将允许您使用环回。
