Akka：如何查找集群中的当前节点？ [英] Akka: How to find the current nodes in a cluster?

问题描述

在Akka演员中，你怎么能找到集群的节点？
也就是说，本地节点认为当前可以访问的节点。

From within an Akka actor, how can you find out the nodes of the cluster? That is, the nodes which the local node considers to be currently accessible.

谢谢，

推荐答案

您实际上不需要订阅 ClusterDomainEvent 或 MemberEvent 。您只需访问群集扩展的州成员，例如

You actually do not need to subscribe to ClusterDomainEvent or MemberEvent. You can just access the state member of the Cluster extension, e.g.,

val cluster = akka.cluster.Cluster(context.system)

val members = cluster.state.members.filter(_.status == MemberStatus.Up)
