Feign拦截器

1. 编写拦截器

com.spring.cloud.common.interceptor.FeignRequestInterceptor

2. 在user-service中配置Feign调用拦截器

feign:
  client:
    config:
      default: # 对所有服务的feign调用有效
        requestInterceptors:
          - com.spring.cloud.common.interceptor.FeignRequestInterceptor
#      spring-cloud-order-service: # 针对特定服务的feign调用有效
#        requestInterceptors:
#          - com.spring.cloud.common.interceptor.FeignRequestInterceptor

在user-service中通过feign调用order-server时，发起的请求都会被该拦截器拦截

3. 在order-service中配置请求拦截器

com.spring.cloud.common.interceptor.FeignAuthInterceptor

该拦截器通过WebMvcConfig配置，相当于web请求拦截器

其它服务对order-service服务发起的调用，包括通过feign发起的，请求都会被该拦截器拦截
