我使用fileinput插件上传文件,请问入口方法该怎么改?
前端配置参数如下:

   var options ={
            language: 'zh', //设置语言
            allowedPreviewTypes : [ 'image' ],
            allowedFileTypes: ['image','text','object','flash'],//默认是['image', 'html', 'text', 'video', 'audio', 'flash','object']
            uploadUrl: "${base}/file/upload/file", //上传的地址
//            allowedFileExtensions : ['jpg', 'png','gif'],//接收的文件后缀,
            maxFileCount: 2000,
            enctype: 'multipart/form-data',
            showUpload: true, //是否显示上传按钮
            showCaption: true,//是否显示标题
            showRemove : true,
            browseClass: "btn btn-primary", //按钮样式             
            previewFileIcon: "<i class='glyphicon glyphicon-king'></i>",
            msgFilesTooMany: "选择上传的文件数量({n}) 超过允许的最大数值{m}!",
    };

入口方法如下:

@AdaptBy(type = UploadAdaptor.class)
    @POST
    @At
    @Ok("json")
    @RequiresAuthentication
    public Object file(@Param("file") TempFile tf, HttpServletRequest req, AdaptorErrorContext err) {
        try {
            if (err != null && err.getAdaptorErr() != null) {
                return NutMap.NEW().addv("code", 1).addv("msg", "文件不合法");
            } else if (tf == null) {
                return Result.error("空文件");
            } else {
                String p = Globals.AppRoot;
                String f = Globals.AppUploadPath + "/file/" + DateUtil.format(new Date(), "yyyyMMdd") + "/" + R.UU32() + tf.getSubmittedFileName().substring(tf.getSubmittedFileName().indexOf("."));
                Files.write(new File(p + f), tf.getInputStream());
                return Result.success("上传成功", Globals.AppBase+f);
            }
        } catch (Exception e) {
            return Result.error("系统错误");
        } catch (Throwable e) {
            return Result.error("图片格式错误");
        }
    }

看日志里面的表单名

经过UploadAdaptor适配后,似乎原有文件名就没了,我想保留原有文件名,咋办?

找到了getSubmittedFileName,谢谢

@wendal 后台如何接收多文件上传呢?适配器适配完之后始终都是一个,代码如下:

    @AdaptBy(type = UploadAdaptor.class)
    @POST
    @At
    @Ok("json")
    @RequiresAuthentication
    public Object file(@Param("file_data")TempFile[] tfs, HttpServletRequest req, AdaptorErrorContext err) {
        try {
            if (err != null && err.getAdaptorErr() != null) {
                return NutMap.NEW().addv("code", 1).addv("msg", "文件不合法");
            } else if (tfs == null) {
                return Result.error("空文件");
            } else {
