Scala Akka|如何在集群中使用allButSelf属性

Question

根据集群的Akka文档，我想向集群中的所有节点发布一条广泛的消息吗？我自己除外。目前，它总是向我发送广泛的信息。

val mediator = DistributedPubSub(context.system).mediator
mediator ! Subscribe("content", self)       // subscribe to the topic named "content"
mediator ! Publish("content", "msg")        // sends the msg out Broad to all nodes including myself

我如何准确地设置文档属性"；allButSelf">

Answer 1

您想要进行

mediator ! DistributedPubSubMediator.Put(testActor)
mediator ! DistributedPubSubMediator.SendToAll(path, msg, allButSelf=false) // it is false by default
