Flex文件上传在使用JSP的struts环境中不起作用

Question

我正在使用 jsp 使用 common-fileupload 进行文件上传。它在 spring blaze-ds 和 flex 环境中运行良好。但是当我在 struts 和 flex 框架中使用相同的 jsp 时，我收到以下错误：

org.apache.jasper.JasperException: 在第 69 行处理 JSP 页面 /pages/Template_Upload.jsp 时发生异常

66:             FileItemFactory factory = new DiskFileItemFactory();
67:             ServletFileUpload upload = new ServletFileUpload(factory);
68:             //List<FileItem> items = upload.parseRequest(request);
69:             List<FileItem> items = upload.parseRequest(request);
70:             out.println(items);
71:             int counter = 0;
72:

请帮帮我.. 提前致谢

更新 这是我的 JSP。我将项目大小设为 0。因此它没有进入 for 循环并在指定路径中创建文件。

 String uploadpath = "C:\\XXXX\\XXXXX\\DataToUpload";
    uploadDir = uploadpath;
    FileItemFactory factory = new DiskFileItemFactory();
    ServletFileUpload upload = new ServletFileUpload(factory);
    List<FileItem> items = upload.parseRequest(request);
    out.println(items);
    int counter = 0;
    for(FileItem item : items) {
        File uploadedFile = new File(uploadDir + File.separator + item.getName());
        uploadedFile.createNewFile();
        try 
         {
          item.write(uploadedFile);
         }
         catch(IOException e) {
           log.error("error" + e);
         }
      }

不，我的表单不包含enctype="multipart/form-data"

那么你得到错误也就不足为奇了

org.apache.commons.fileupload.FileUploadBase$InvalidContentTypeException：请求不包含多部分/表单数据或多部分/混合流，内容类型标头为空

不知道flex文件上传，但是上传文件的时候，内容必须是multipart/form-data。

如果没有指定内容类型，则使用默认的：application/x-www-form-urlencoded
