SpringCloud学习（二）：Feign 接口调用服务

菜鸟学渣接触spring cloud 系列...

公司也上微服务了，再不学习下就凉了，所以来踩坑吧...

版本：

　　spring-boot: 2.0

　　spring-cloud: Finchley.SR1

已有项目：

　　[eureka-server] # 注册中心

　　[eureka-client-one] # 微服务1

能上图绝不BB：

　　 SpringCloud学习（二）：Feign 接口调用服务

微服务之间的接口相互调用，使用的是Feign，比HTTPClient好用多了...

一、Feign端 [eureka-client-two]

　　这里新建一个微服务[eureka-client-two]调用[eureka-client-one]中的helloworld接口

　　主要引入依赖 spring-cloud-starter-openfeign
