设置Feign的Header信息

两种方式

1.在方法参数前面添加@RequestHeader注解

@PostMapping(value = "/getStuDetail")public ReturnInfo getStudentDetail(@RequestBody Map map,@RequestHeader(name = "id") String id);

使用@RequestHeader(name = "id")可以传递动态header属性

2.实现RequestInterceptor接口,设置Header(所有Feign请求)

import org.springframework.context.annotation.Configuration;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import feign.RequestInterceptor;import feign.RequestTemplate;@Configurationpublic class FeignConfiguration implements RequestInterceptor {         @Override          public void apply(RequestTemplate template) {                   ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();                   HttpServletRequest request = attributes.getRequest();                    Enumeration
    
      headerNames = request.getHeaderNames();                   if (headerNames != null) {                             while (headerNames.hasMoreElements()) {                                    String name = headerNames.nextElement();                                     String values = request.getHeader(name);                                    template.header(name, values);                              }                        }         }}//configuration = FeignConfiguration.class===================@Component@FeignClient(value = "xxxxxxxxx",fallback = XxxxxServiceHystric.class ,configuration = FeignConfiguration.class)public interface XxxxxService {}
