001、引用FeignClient循环依赖问题

1.报错信息

HandlerInterceptor引用FeignClient造成循环依赖

The dependencies of some of the beans in the application context form a cycle:

┌─────┐

| appAuthInterceptor defined in URL [jar:file:/deployments/app.jar!/BOOT-INF/classes!/com/XX/assembler/interceptor/AppAuthInterceptor.class]

↑ ↓

| hpcCommonServiceImpl (field private com.XX.assembler.client.HpcCommonFeignClient com.XX.assembler.service.impl.HpcCommonServiceImpl.hpcCommonFeignClient)

↑ ↓

| com.XX.assembler.client.HpcCommonFeignClient

↑ ↓

| org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration

↑ ↓

| interceptorConfiguration (field private com.XX.assembler.interceptor.AppAuthInterceptor com.XX.assembler.config.InterceptorConfiguration.appAuthInterceptor)

└─────┘

错误信息如下：
