Feign远程调用丢失请求头问题

feign远程调用时会构建一个新的请求模板

 解决：

　　使用feign请求拦截器requestInterceptor给新的请求模板加上请求头

@Configuration
public class GuliFeignConfig {
    @Bean("requestInterceptor")
    public RequestInterceptor requestInterceptor(){
        return new RequestInterceptor() {
            @Override
            public void apply(RequestTemplate template) {
                //1、RequestContextHolder拿到刚进来的请求
                ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
                if (attributes!=null){
                    HttpServletRequest request = attributes.getRequest(); //老请求
                    //同步请求头数据,Cookie
                    String cookie = request.getHeader("Cookie");
                    //给新请求同步了老请求的cookie
                    template.header("Cookie",cookie);
                }
            }
        };
    }
}
