【踩的坑】springcloud-服务消费者:feign篇--该引用哪套版本的jar包问题

( 我springCloud学习追的是博客  史上最简单的SpringCloud教程 系列 )


@FeignClient 该引用哪个包

 

史上最简单的SpringCloud教程系列 用的是  spring-cloud-netflix-core 包 

但 我的spring springboot 版本是

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.6.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
</properties>

所以 启动会报错

(百度说 报这个错 是因为 jar包版本不一致)

 

所以 我改引用 spring-cloud-starter-openfeign 包


jar 包 引用如下:
