                <label>显示类型:
                    <select id="flag" name="flag">
                        <option value="0">所有人可见</option>
                        <option value="1">仅自己可见</option>

            </div>
            <div class="row btn-group-m-t">
                <div class="col-sm-10">

                    <#button btnCss="info" name="提交" id="ensure" icon="fa-check" clickFun="ArticleInfoDlg.addSubmit()"/>
                    <#button btnCss="danger" name="取消" id="cancel" icon="fa-eraser" clickFun="ArticleInfoDlg.close()"/>
                </div>
            </div>
        </form>

ajaxSubmit 的 JS:

//图片上传 及数据保存
    var options = {
        url: Aexit.ctxPath + "/Article/add",
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        success: function (data) {
// 如果图片上传成功则保存表单注册数据
            if(data.code == 0) {
                window.parent.Article.table.refresh();
                ArticleInfoDlg.close();
            } else {
                Aexit.error(data.message);
            }
        }
    };
// 提交表单
    $('#ArticleForm').ajaxSubmit(options);

Controller接收：

 private final String resourceLocation = "D://img/";
@RequestMapping(value = "/add", method = RequestMethod.POST)
    @ResponseBody
    public AjaxCommonObject add(HttpServletRequest request, MultipartFile picture, HttpSession session) {

        String title = request.getParameter("title");
        String content = request.getParameter("content");
        String f = request.getParameter("flag");
        String ids = request.getParameter("id");
        Integer flag = Integer.parseInt(f);
        Integer id = Integer.parseInt(ids);

        Article dto = new Article();
        AjaxCommonObject ajaxCommonObject = new AjaxCommonObject();

        if (picture != null) {


            String fileName = UUID.randomUUID().toString().replaceAll("-", "") + picture.getOriginalFilename().substring(picture.getOriginalFilename().lastIndexOf("."));

            // 文件上传后的路径
            String filePath = resourceLocation;

            File dest = new File(filePath + fileName);
            // 检测是否存在目录
            if (!dest.getParentFile().exists()) {
                dest.getParentFile().mkdirs();
            }
            try {
                picture.transferTo(dest);

            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            String paths = fileName;
            String path = filePath + "/" + fileName;//文件路径
            SysUser user = (SysUser) session.getAttribute(AuthConstants.CURRENT_USER);
            Integer author = user.getId();
            dto.setAuthor(author);
            dto.setTitle(title);
            dto.setContent(content);
            dto.setFlag(flag);
            Date date = new Date();
            dto.setUpdatetime(date);
            dto.setPicture(paths);
            dto.setArticletype(id);
            try {

                bizService.add(dto); //返回新增记录的表id

            } catch (BizCommonException e) {
                return new AjaxCommonObject(e);
            }
        }
        return ajaxCommonObject;
    }
