### 消费者与提供者 ###

启动**nacos**

> ### Linux/Unix/Mac ###
> 
> sh startup.sh -m standalone
> 
> # windows #
> 
> startup.cmd -m standalone

配置文件application.yml

spring:
      application:
    	name: spring-provide
    cloud:
      nacos:
    	discovery:
    	  server‐addr: 127.0.0.1:8848 # 注册中心地址

其余配置是与eureka版是差不多的。
