Could not parse multipart servlet request

之前上传文件都是没有问题的，不知道为啥出现这样的问题：Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadException: Input length = 1？

前端是这样的：

<form enctype="multipart/form-data" id="batchUpload"  action="" method="post" class="form-horizontal">
   <table>
      <tr>
         <td >
            <input type="file" name="file"  style="width:0px;height:0px;" id="uploadEventFile">
            <input id="uploadEventPath"  disabled="disabled"  type="text" placeholder="请选择excel表" style="border: 1px solid #e6e6e6; height: 115px;width: 400px;" >
         </td>
      </tr>
      <tr>
         <td align="center">
            <cui:button label="选择文件"  id="uploadEventBtn" componentCls="btn-primary" style="height:40px;width :185px"  type="button" />
            <cui:button label="上传文件" type="button"  componentCls="btn-primary" style="height:40px;width :183px" onClick="uploadBtn()" />
         </td>

      </tr>
   </table>

</form>

js:

$(function(){
           //模拟上传excel
           $("#uploadEventBtn").unbind("click").bind("click",function(){
               $("#uploadEventFile").click();
           });
           $("#uploadEventFile").bind("change",function(){
               $("#uploadEventPath").attr("value",$("#uploadEventFile").val());
           })
       });

       //点击上传按钮
       function uploadBtn(){
           debugger;
           var uploadEventFile = $("#uploadEventFile").val();
           if(uploadEventFile == ''){
               $.message({message:"请选择excel,再上传！", cls:"waring"});
           }else if(uploadEventFile.lastIndexOf(".xls")<0){//可判断以.xls和.xlsx结尾的excel
               $.message({message:"只能上传Excel文件！", cls:"waring"});
           }else{
               debugger;
               var formData = new FormData($("#batchUpload")[0]);
               var ul =  '${ctx}/zbgl/zbbp/validateDutydate';
               $.loading({text:"正在处理中，请稍后..."});
               $.ajax({
                   url: ul,
                   type: "POST",
                   data:formData,
                   dataType: "json",
                   processData: false,  // 告诉jQuery不要去处理发送的数据
                   contentType: false,   // 告诉jQuery不要去设置Content-Type请求头
                   success: function (data) {
                       debugger;
                       if(data.code == "1"){
                           $.loading("hide");
                           $.message({message:data.msg, cls:"waring"});
                       }else if(data.code == "300"){
                           $.loading("hide");
                           $.message({message:data.msg, cls:"waring"});
               }else if(data.code == "500"){
                           $.loading("hide");
                           $.message({message:"操作失败！", cls:"waring"});
               } else if(data.code == "200") {
                          
                       
                 }
               });
           }
       };

controller层：

@RequestMapping(value = "/validateDutydate")
@ResponseBody
@Logger(action = "获取", logger = "获取传入的excal文件", model = "值班编排")
public Map<String, Object> validateDutydate(MultipartFile file, HttpServletRequest request, HttpServletResponse response) {
    Map<String, Object> map = new HashMap<>();
    try {
        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
        // 获取传入文件
        InputStream inputStream = file.getInputStream();
        zbbpService.validateDutydate(inputStream);
        map.put("code", 200);
    } catch (AlreadyHasDutyListOnDutyDayException duty) {
        duty.printStackTrace();
        map.put("code", 1);
        map.put("msg", duty.getMessage());
    } catch (IOException e) {
        e.printStackTrace();
        map.put("code", 300);
        map.put("msg", "文件读取异常！");
    } catch (Exception e) {
        e.printStackTrace();
        map.put("code", 500);
    }
    return map;
}

后端一直进不去，这是什么问题？
