从JSP导出后无法在Excel中加载数据

Question

当我尝试导出文件时，错误为java.lang.NumberFormatException: For input string: "loadltklSubmitInfo" 这是我制作Excel文件的JSP：

<tr>
    <th>Nama File Zip</th>
    <th>Jumlah Data LTKL Terkirim</th>
    <th>Jumlah Data LTKL Terproses</th>
    <th>Jumlah Data LTKL Sukses</th>
    <th>Tanggal Kirim</th>
    <th>Tanggal Terima</th>         
</tr>
<c:forEach items="${data.loadltklSubmitInfo}" var="ltklSubmit">        
    <td><c:out value="${ltklSubmit.zipFileName}" /> </td>
    <td><c:out value="${ltklSubmit.ltklCount}" /></td>
    <td><c:out value="${ltklSubmit.ltklCountProcess}" /></td>
    <td><c:out value="${ltklSubmit.ltklCountSuccess}" /></td>
    <td><fmt:formatDate value="${ltklSubmit.sentDate}" pattern='dd/MM/yyyy HH:mm:ss'/></td>
    <td><fmt:formatDate value="${ltklSubmit.receiveDate}" pattern='dd/MM/yyyy HH:mm:ss'/></td>

</c:forEach>

这是我的控制器

@RequestMapping ("/cekSubmitExport.htm")
public ModelAndView loadExportExcelLTKL (HttpServletResponse response, HttpServletRequest request)
{
    response.setHeader("Pragma", "No-Cache");
    response.setHeader("Cache-Control", "no-cache");
    response.setContentType("application/vnd.ms-excel");
    response.setDateHeader("Expires", 1);

    //String type = request.getParameter("type");
    String file = request.getParameter("zipFileName");


    ModelAndView view = new ModelAndView("cekSubmitExportView");

    //if (type.equals("1"))
    //{
        response.setHeader("Content-Disposition", "inline; filename=HasilSubmitLTKL.xls");
        //view.addObject("flag", "1");
        view.addObject("data", exportExcelService.getltklSubmitInfoByFile(file));

这是我的服务：

@Autowired
private LtklSubmitInfoDao ltklSubmitInfoDao;


@Transactional(readOnly = false, propagation = Propagation.REQUIRED, isolation = Isolation.SERIALIZABLE, rollbackFor = {Exception.class})
public List<LtklSubmitInfo> getltklSubmitInfoByFile(String zipFileName)
{
    return ltklSubmitInfoDao.loadAll(zipFileName);
}
