请问，strus 如何实现上传文件、图片

[Delphicaijie]

郁闷哪，无从下手！

首先，谢谢上边的朋友！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！
　　照着做了，应该代码没有问题，但是，好像文件并没有上传到指定的服务器目录中,在应用程序的WebRoot目录下（application\WebRoot\userbase\document）。
当然，也无法打开（下载）此上传的文件之后，我是试着将文件直接拷贝到相应目录（application\WebRoot\userbase\document），但是还是不行！有大侠知道是怎么一回事吗？
对了，报的错误如下：
HTTP Status 404 - /application/USERBASE/document/%E5%BC%80%E5%8F%91%E9%9C%80%E6%B1%82%E5%86%85%E5%AE%B9.doc
type Status report

message /application/USERBASE/document/%E5%BC%80%E5%8F%91%E9%9C%80%E6%B1%82%E5%86%85%E5%AE%B9.doc

description The requested resource (/application/USERBASE/document/%E5%BC%80%E5%8F%91%E9%9C%80%E6%B1%82%E5%86%85%E5%AE%B9.doc) is not available.
要说明的是，程序可以运行的起来，其他模块也OK。

网上不是有插件吗？你可以看看风中叶的struts2视频教程，里面讲的很详细

在网上找找相关的资料，弄一下就好了。

[flybird]

<% @ taglib prefix = " st " uri = " /struts-tags " %>

<st:file name ="myFile" label ="Select File" />

后台的action中直接定义 File myFile = null;

取出来的就是上传的file。

上传文件用到commons-fileupload-1.2.1.jar

FileItemFactory factory = new DiskFileItemFactory();
		ServletFileUpload upload = new ServletFileUpload(factory);
		upload.setHeaderEncoding("utf-8");
		List list = upload.parseRequest(request);
		Iterator iter = list.iterator();
		FileItem item = null;
		String filePath = "";
		String fileName = "";
		String s = "";
		String suffix = "";
		long size = 0 ;
		while (iter.hasNext()) {
			item = (FileItem) iter.next();
			if (!item.isFormField()) {
				fileName = item.getName();
				s = fileName.substring(fileName.lastIndexOf("\\") + 1);
				suffix = s.substring(s.lastIndexOf("."));
				s = uuid + suffix;
				filePath = ConstantFactory.getConstant("path.upload.dcm").concat("\\\\").concat(s);
				size = item.getSize();
				if (size != 0) {
					File uploadedFile = new File(filePath);
					item.write(uploadedFile);
				}
			}
		}

FormBean:

public class PersoForm extends ActionForm {
    private FormFile pic;
	public FormFile getPic() {
		return pic;
	}
	public void setPic(FormFile pic) {
		this.pic = pic;
	}
...

Action:

	public ActionForward persis(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws SQLException {
		Integer id=0;
		if(!request.getParameter("id").equals(""))id=new Integer(request.getParameter("id"));
		boolean self=false;
		Perso psSess=(Perso)request.getSession().getAttribute("u");
		if(psSess.getId().equals(id))self=true;
		SimpleDateFormat df=new SimpleDateFormat("MMddHHmmss");		
		String datStr=df.format(new Date());
		PersoForm uf=(PersoForm)form;	
		uf.setPsw(null);
		//Ou.pl(uf.getPsw());
		Perso ps=new Perso();
		BeanUtils.copyProperties(uf,ps);
		
		if(self){
			ps.setJobid(new Integer(request.getParameter("job2")));
			ps.setGroupid(new Integer(request.getParameter("gru2")));
		}
		if(ps.getGroupid()>4)ps.setJobid(uf.getJobid());
		String dir="";
        try {   
            if(uf.getPic().getFileName()==null||uf.getPic().getFileName().equals("")){   
            	request.setAttribute("msg", "未选择文件上传");
            }else{   
                String uploadPath = request.getSession().getServletContext().getRealPath("/");   
                dir="\\upload\\sig"+datStr+"."+(uf.getPic().getFileName().split("\\.")[1]) ;   
                String dir1=uploadPath+dir;   
                OutputStream out=new FileOutputStream(new File(dir1));   
                   System.out.println(uf.getPic());   
                   byte b[]=uf.getPic().getFileData();   
                   out.write(b);   
                   out.close();   
                   ps.setPhoto("/upload/sig"+datStr+"."+uf.getPic().getFileName().split("\\.")[1]); 
            }   
       } catch (FileNotFoundException e) {   
           e.printStackTrace();   
       } catch (IOException e) {   
           e.printStackTrace();   
       } 
		try{
		persoBiz.persis(ps);
		}catch(SQLException e){
			if(e.getErrorCode()==1062){
				request.setAttribute("msg", "已存在");
				return mapping.findForward("mm");
			}
		}
		request.setAttribute("msg", "已保存"+ps.getName());
		if(self)
		return new ActionForward("/perso.do?op=pre&id="+id);
		else
		return mapping.findForward("lis");
