Question

我正在使用jsp进行文件上传，使用common-fileupload.It在spring blaze-ds和flex环境下工作正常。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.. 在此先感谢

已更新 这是我的JSP。我将项目大小设置为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);
         }
      }

我的表单不包含enctype="multipart/form-data"

然后，您收到错误并不奇怪

org.apache.commons.fileupload.FileUploadBase $ InvalidContentTypeException：请求不包含multipart / form-data 或multipart / mixed流，内容类型标头为null

我不知道Flex文件上传，但上传文件时，内容必须为multipart/form-data。

如果未指定内容类型，则使用默认内容类型：application/x-www-form-urlencoded

Flex文件上载在使用JSP的struts环境中不起作用
