根据错误分析发现是IllegalStateException参数异常，往后分析可以得出是在注入loadbalancer组件时异常，所以我们缺少了spring-cloud-starter-loadbalancer依赖，导入即可。另外根据spring官方文档也可以窥探一二。

在这里插入图片描述

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'memberController' defined in file [E:\开源\zmall\zmall-member\target\classes\com\zsh\member\controller\MemberController.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.zsh.member.feign.CouponService': Unexpected exception during bean creation; nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?
