  1.   

    servlet代码：
           public class UploadServlet extends HttpServlet {
    private static final long serialVersionUID = 1L; public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
    doPost(request, response);
    } public void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
    request.setCharacterEncoding("gbk");
    SmartUpload su = new SmartUpload();
    String fileName = "";
    String sfilelength = "";
    String filetype = "";
    String suploadtime = "";
    UploadEntity uploadentity = new UploadEntity();
    try {
    su.initialize(this.getServletConfig(), request, response);
    su.upload();
    String title = su.getRequest().getParameter("title");
    String re = su.getRequest().getParameter("re");
    su.save("F://upload"); File file = su.getFiles().getFile(0);
    fileName = file.getFieldName();
    int ifilelength = file.getSize();
    sfilelength = Integer.toString(ifilelength);
    filetype = file.getFileExt();
    Date dt = new Date();
    suploadtime = String.valueOf(1900 + dt.getYear() + "-"
    + String.valueOf(1 + dt.getMonth()) + "-"
    + String.valueOf(dt.getDate())); uploadentity.setFileName(fileName);
    uploadentity.setFileLength(sfilelength);
    uploadentity.setFileType(filetype);
    uploadentity.setFileUploadTime(suploadtime);
    uploadentity.setFileTitle(title);
    uploadentity.setFileDescribe(re);
    UploadManage um = new UploadManage();
    um.upload(uploadentity);
    request.getRequestDispatcher("/result.jsp").forward(request,
    response);
    } catch (Exception e) {
    e.printStackTrace();
    }
    }
    public void init(ServletConfig config) throws ServletException {
    }
    }
