Caused by: java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forge

工具最后日志标注一下错误，或者包含其中错误内容：

        Caused by: java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

由于Spring Cloud Feign在Hoxton.M2 RELEASED版本之后不再使用Ribbon而是使用spring-cloud-loadbalancer，所以不引入spring-cloud-loadbalancer会报错.

解决方法：
加入spring-cloud-loadbalancer依赖 并且在nacos中排除ribbon依赖，不然loadbalancer无效

排除ribbon依赖

   com.alibaba.cloud
    spring-cloud-starter-alibaba-nacos-discovery
    
        
            com.netflix.ribbon
            ribbon
        
    

添加依赖

    org.springframework.cloud
    spring-cloud-loadbalancer

如果还是没有解决，请去官方查阅框架对应的版本，实在不行将spring boot和spring cloud的来版本全部降下

注意：最新版本添加依赖后，可能会出现一下错误，循环调用

Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

可在配置文件中设置：

spring.main.allow-circular-references = true.
