Question

我正在尝试上传文件和文本字段。虽然据说我无法使用request.getParameter("remarks");检索文本字段的值，但我导入了commons-fileupload。虽然我似乎无法弄清楚我的代码有什么问题，但这行中有错误List<FileItem> items = upload.parseRequest(request);说SEVERE: Servlet.service() for servlet [SubmitResult] in context with path [/HIS] threw exception [Servlet execution threw an exception] with root cause java.lang.ClassNotFoundException: org.apache.commons.io.IOUtils

HTML：

<div class="modal-body">
    <input type="hidden" name="orderid2" id="orderid2">
    <table>
        <tr>
            <td>
                Remarks:
            </td>
            <td>
                <input type="text" name="remarks" placeholder="Remarks" autocomplete="off" class="form-control placeholder-no-fix"> <br>
            </td>
        </tr>
        <tr>
            <td>
                Upload File: &nbsp;
            </td>
            <td>
                <input type="file" name="file" id="file" accept="image/png, .txt, application/pdf, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel, application/vnd.openxmlformats-officedocument.wordprocessingml.document,application/msword"/> <br>
            </td>
        </tr>
    </table>
</div>

的Servlet

    String rtempfile = File.createTempFile("temp", "1").getParent();
    MultipartRequest multi = new MultipartRequest(request, rtempfile, 15*1024*1024);
    Enumeration files = multi.getFileNames();

    DiskFileItemFactory factory = new DiskFileItemFactory();
    ServletFileUpload upload = new ServletFileUpload(factory);
    List<FileItem> items = upload.parseRequest(request);
    Iterator<FileItem> iter = items.iterator();
    while(iter.hasNext()) {
        FileItem item = iter.next();
        if(item.isFormField()) {
        String name = item.getFieldName();
        String value = item.getString();
            if(name.equals("orderid2"))
                order.setOrderID(Integer.parseInt(value));
            else if(name.equals("remarks"))
                order.setRemarks(value);
        }
    }
    orderDAO.submitResult(order, multi, files);
