  • 所有已实现的接口:
    java.util.EventListener, org.springframework.context.ApplicationListener<org.springframework.boot.web.context.WebServerInitializedEvent>
    @Component("serverMemberManager")
public class ServerMemberManager
extends java.lang.Object
implements org.springframework.context.ApplicationListener<org.springframework.boot.web.context.WebServerInitializedEvent>
    Cluster node management in Nacos.

    init() Cluster node manager initialization shutdown() The cluster node manager is down getSelf() Gets local node information getServerList() Gets the cluster node dictionary getMemberAddressInfos() Gets the address information of the healthy member node allMembers() Gets a list of member information objects allMembersWithoutSelf() Gets a list of cluster member nodes with the exception of this node hasMember(String) Is there a node memberChange(Collection) The final node list changes the method, making the full size more memberJoin(Collection) Node join, can automatically trigger memberLeave(Collection) When the node leaves, only the interface call can be manually triggered update(Member) Update the target node information isUnHealth(String) Whether the target node is healthy initAndStartLookup() Initializes the addressing mode
