本文使用SpringCloud结合Nacos服务发现，Feign远程调用做一个简单的Demo。

1 Nacos

关于Nacos之前写了两篇文章关于SpringBoot对它的使用，感兴趣可以查看一下。

《SpringBoot使用Nacos配置中心》

《SpringBoot使用Nacos服务发现》

在SpringBoot使用的时候，需要自行去向Nacos服务注册自己的服务，Nacos也提供了SpringCloud服务发现的依赖，本文结合spring-cloud-starter-alibaba-nacos-discovery进行使用介绍。

本文使用版本为:

SpringCloud Finchley.SR2
SpringBoot 2.0.3.RELEASE
spring-cloud-starter-alibaba-nacos-discovery 0.2.1.RELEASE
spring-cloud-starter-openfeign 2.0.0.RELEASE

2.本文场景

两个服务，如下：

springcloud-nacos-discovery-provider：端口号10000，服务提供者。
springcloud-nacos-discovery-consumer：端口号10001，服务消费者。

原理很简单，浏览器访问消费者，消费者调用服务提供者。

3.服务提供者

3.1 依赖配置

创建一个项目，项目中加入SpringCloud-Nacos依赖，完整pom如下所示。
