Feign客户端口token令牌丢失解决

加入一个bean

@Bean("requestInterceptor")
    public RequestInterceptor requestInterceptor(){
        return template -> {
            ServletRequestAttributes attributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
            if(attributes!=null){
                HttpServletRequest request = attributes.getRequest();
                if (null == request){
                    return;
                }
                log.info(request.getHeaderNames().toString());
                template.header("token", request.getHeader("token"));
            }else {
                log.warn("requestInterceptor获取Header空指针异常");
            }
        };
    }
