@RefreshScope // 动态刷新

以前ribbon,现在的loadBalanced。客户端负载均衡consul配置持久化
新建mydata文件夹，
新建consul_start.bat文件
内容如下
@echo.服务启动......
@echo off
@sc create Consul binpath= "D:\Downloads\consul_1.21.5_windows_amd64\consul.exe agent -server -ui -bind=127.0.0.1 -client=0.0.0.0 -bootstrap-expect 1 -data-dir D:\Downloads\consul_1.21.5_windows_amd64\mydata  "
@net start Consul
@sc config Consul start= Auto
@echo.Consul start is OK......success
