Scala \如何在集群中使用allButSelf属性？

Question

基于Akka集群文档，我是否希望向集群中的所有节点发布一条宽消息，除了亲自。目前，它也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

如何设置文档属性"allButSelf"?

Answer 1

你想做什么

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

参见这里的示例https://github.com/akka/akka/blob/0e4d41ad33dbeb00b598cb75b4d29899371bdc8c/akka-cluster-tools/src/test/scala/akka/cluster/pubsub/DistributedPubSubMediatorRouterSpec.scala#L56
