初步使用nacos

服务注册到nacoas

注： up的父工程依赖

1.在父工程里面添加依赖

2.在需要注册的项目客户端中添加依赖

3，配置nacos的配置地址

一。服务集群属性

1.在application.yml ,添加如下，设置集群

spring:

        cloud:

                nacos:

                        serves-addr: localhost:8848 #nacos的服务端地址

                        discovery:

                                cluster-name: HN #配置集群名称，即机房位置湖南

2.配置负载均衡规则优先寻找与自己同集群的服务
