COS文件上传组件在Struts1.X环境下的问题[SOS]
紧急救援问题是这样的：
我使用文件上传组件COS进行文件的上传操作，按照COS的例子，我也成功的做了一个Demo,但这个Demo是这样的.有两个JSP文件:
a.jsp(用于生成上传界面)
upload.jsp(内嵌了javaCode实现文件上传操作)
我想对他进行点改进，就是说：我实现文件上传的代码我想写在StrutsAction中，而不是嵌在一个JSP里面.具体我是怎么写的，请看下面的代码:
a.jsp的代码如下:
<!-- 测试集成COS文件上传效果 --><%@ page contentType="text/html; charset=GBK"%><html><body><form name="form1" method="post" enctype="multipart/form-data"action="upload.jsp"><input name="file1" type="file"><br><input name="file2" type="file"><br><input name="file3" type="file"><br><input type="submit" name="Submit"value="上传"></form></body></html>
upload.jsp的代码如下:
<%@ page contentType="text/html; charset=gb2312" %><%@ page import="java.util.Enumeration"%><%@ page import="com.oreilly.servlet.MultipartRequest" %><%@ page import="java.io.File" %><html><head></head><body> <% String saveDirectory = "c:\\upload"; //每个文件最大5m,最多3个文件 int maxPostSize = 3 * 5 * 1024 * 1024; //response的编码为"gb2312",同时采用缺省的文件名冲突解决策略,实现上传 MultipartRequest multi = new MultipartRequest(request,saveDirectory, maxPostSize, "gb2312"); //输出反馈信息 Enumeration file = multi.getFileNames(); while (file.hasMoreElements()) { String name = (String) file.nextElement(); File f = multi.getFile(name); if (f != null) { String fileName = multi.getFilesystemName(name); String lastFileName = saveDirectory + "\\" + fileName; out.println("文件已经上传到:" + lastFileName); out.println("<br>"); } } %></body></html>
通过上面的两个JSP文件，我成功的完成了我的上传操作!
但是，我把它移植到Struts的Action中就报错了。请继续往下看:
a-1.jsp的代码如下:
<!-- 测试集成COS文件上传效果 --><%@ page contentType="text/html; charset=GBK"%><html><body><form name="form1" method="post" enctype="multipart/form-data"action="/uploadAction.do"><input name="file1" type="file"><br><input name="file2" type="file"><br><input name="file3" type="file"><br><input type="submit" name="Submit"value="上传"></form></body></html>
UploadActionForm.java的代码如下:
public class UploadActionForm extends ActionForm {private FormFile file1 = null;private FormFile file2 = null;private FormFile file3 = null; ........ ........//省略
UploadAction的代码如下:
public class UploadAction extends Action {/** * @name execute * @title 测试文件上传组件COS集成效果 * @param ActionMapping,ActionForm,HttpServletRequest,HttpServletResponse * @return ActionForward * @description */public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception { String saveDirectory = "c:\\upload"; //每个文件最大5m,最多3个文件 int maxPostSize = 3 * 5 * 1024 * 1024; //response的编码为"gb2312",同时采用缺省的文件名冲突解决策略,实现上传 MultipartRequest multi = new MultipartRequest(request,saveDirectory, maxPostSize, "gb2312"); //输出反馈信息 Enumeration file = multi.getFileNames(); while (file.hasMoreElements()) { String name = (String) file.nextElement(); File f = multi.getFile(name); if (f != null) { String fileName = multi.getFilesystemName(name); String lastFileName = saveDirectory + "\\" + fileName;response.getWriter().println("文件被上传到:" + lastFileName);response.getWriter().println("<br>"); } }return mapping.findForward("jspView");}}
我请求这个页面的时候，控制台报出如下错误信息:

不知如何解决，请指教,
