关于multipart/form-data请求的处理问题

有这么一个应用场景：
对接支付接口，发送下单请求参数，获取同步响应中的支付链接实际支付之后，上游会根据下单请求参数中的notify_url地址发送支付成功的异步回调通知，现在遇到一个发送过来的回调信息是 form表单属性enctype为“multipart/form-data”的，用getParameter()方法取不到值，请问应该怎么解析这种请求发过来的回调数据？

@AdaptBy(type=WhaleAdaptor.class)

或者当文件上传用UploadAdaptor

添加之后，后台打印

我这时候，除了用 @Param("status") String status 形参注解的形式获取字段对应的值之外，是否方法直接从 HttpServletRequest 中获取值，因为发来的字段数量和名称是不确定的，需要转一下存到map里

找到解决方法了，后台代码如下

 @At("/notify")
    @Ok("raw")
    @AdaptBy(type = WhaleAdaptor.class)
    public String notify(@Param("..") Map map) throws IOException {
        log.debug("map-------:" + Json.toJson(map, JsonFormat.full()));
        return Json.toJson(map);
    }

添加了@AdaptBy(type = WhaleAdaptor.class)之后，形参用一个map接收一下，直接就是请求中的键值对
