1.jsp文件

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

    My JSP 'upload.jsp' starting page

2.servlet类(在servlet里直接进行上传操作)

package com.zyc.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Calendar;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.jsp.JspFactory;
import javax.servlet.jsp.PageContext;

import com.jspsmart.upload.SmartUpload;

public class UpLoad extends HttpServlet {

/**
* Constructor of the object.
*/
public UpLoad() {
super();
}

/**
* Destruction of the servlet.

*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}

/**
* The doGet method of the servlet.

*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.setContentType("text/html");

}

/**
* The doPost method of the servlet.

*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

  response.setContentType("text/html");

  SmartUpload mySmartUpload =new SmartUpload();
  long file_size_max=4000000;
  String fileName2="",ext="",testvar="";
  String url="images/";
   try{
        JspFactory _jspxFactory = null;
        PageContext pageContext = null;
        _jspxFactory = JspFactory.getDefaultFactory();
        pageContext = _jspxFactory.getPageContext(this,request,response,"",true,8192,true);

        mySmartUpload.initialize(pageContext);

        mySmartUpload.setAllowedFilesList("jpg,gif");
//      上载文件
       mySmartUpload.upload();

       com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(0);

       String myFileName=myFile.getFileName(); //取得上载的文件的文件名
       ext= myFile.getFileExt();
       int file_size=myFile.getSize();
       String saveurl="";
       Calendar calendar = Calendar.getInstance();
       String filename = String.valueOf(calendar.getTimeInMillis());
       saveurl=request.getRealPath("/")+url;
       saveurl+=filename+"."+ext;
       myFile.saveAs(saveurl,mySmartUpload.SAVE_PHYSICAL);

   }catch(Exception e){
    e.printStackTrace();
   }
}

/**
* Initialization of the servlet.

*
* @throws ServletException if an error occure
*/
public void init() throws ServletException {
// Put your code here
}

}
