关于上个问题的解答

隔天找到问题后忘了更新了直接上代码

这是我原来的pom文件

一开始报的是这个错误：java: 无法访问org.springframework.cloud.client.discovery.EnableDiscoveryClient

类文件具有错误的版本 61.0, 应为 52.0，中间还有一段懒得从新找了，不过大概的意思是spring版本兼容问题，所以我的目光一直是放在springboot、springcloud alibaba以及jdk的版本上，一直再排查，结果还是那个前面哪个问题，一直没找出来，太晚就去睡觉了嘿嘿。

隔天重新排查的时候，终于是找到问题的所在了。之前创建项目的时候选了springcloud的openFegin,然后在创建完项目后，我又变动了spring的版本，所以就出现错误了。

        <java.version>1.8</java.version>
        <spring-cloud.version>Greenwich.SR3</spring-cloud.version>
    </properties>
