@Component(value="serverMemberManager")
public class ServerMemberManager
extends java.lang.Object
implements org.springframework.context.ApplicationListener<org.springframework.boot.web.context.WebServerInitializedEvent>

Cluster node management in Nacos.

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