一个项目有多个feignClient报错

Question

原项目有用feign在拦截器上调用会员中心服务来校验用户权限，最近这个项目需要调用另外一个商城相关的服务，所以又写了个feignclient，但是报错，看报错感觉像是循环注入了（报错信息摘要如下），我看了下好像是【orderController -> payOrderFacade(聚合类) -> pmsTermGoodsService（当前项目实现类） -> sscClient（商城中心） -> webConfigure -> authInterceptor（拦截器） -> memberClient（拦截器autowire的member的feign客户端） 】但是不太清楚为什么会这样，这种情况是循环注入还是说一个项目里不能定义有多个feign客户端来调用其他服务呢，求老师解答

看着像是循环调用，一旦用了拦截器，一不小心就出现循环调用，查问题从拦截器里着手。

• 提问者 寒暄丶 #1

  使用了@Lazy注解让其中一个client执行了懒加载，不知道这样治标不治本的方式可不可以用

• 廖师兄 回复 提问者 寒暄丶 #2

  建议把逻辑多缕缕清楚，死循环肯定是逻辑不通。

  根本不是业务循环依赖问题=-=，应该是feignclient使得spring组件mvcResourceUrlProvider出现循环依赖了
  我也是拦截器使用了feignClient，就报错:
  userLoginerAuthTransactionalService(业务bean1)
  loginerClientService(业务bean2)
  loginerUpdateService(业务bean3)
  loginerUpdateFeignService(业务feignclient)
  org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration
  authInterceptor(登录拦截器)
  loginClientService(业务bean4)
  loginerQueryService(业务bean5)
  loginerQueryFeignService(业务feignclient2)
   Error creating bean with name 'mvcResourceUrlProvider': Requested bean is currently in creation: Is there an unresolvable circular reference?
