<%@ page language="java" pageEncoding="UTF-8"%> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

 <body> 
 <form action="upload" method="post" enctype="multipart/form-data">

 姓名：<input type="text" name="uname"/> 
 <br> 
 上傳文件:<input type="file" name="pic"/> 
 <br> 
 <input type="submit" value="提交"></input> 
 </form> 
 </body> 
</html>

2、action跳轉(zhuǎn)到了upload的servlet，所以要web.xml里面配置，web.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
 <servlet> 
 <servlet-name>uploadAction</servlet-name> 
 <servlet-class>com.pop.action.SmartuploadAction</servlet-class> 
 </servlet> 
 <servlet-mapping> 
 <servlet-name>uploadAction</servlet-name> 
 <url-pattern>/upload/*</url-pattern> 
 </servlet-mapping> 
 <welcome-file-list> 
 <welcome-file>index.jsp</welcome-file> 
 </welcome-file-list> 
</web-app>

3、映射到的action文件，SmartuploadAction.java:

package com.pop.action; 
 
import java.io.IOException; 
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.soft4j.httpupload4j.Request; 
import com.soft4j.httpupload4j.SmartUpload; 
import com.soft4j.httpupload4j.SmartUploadException; 
 
public class SmartuploadAction extends HttpServlet { 
 private static final long serialVersionUID = -8610555375032925108L; 
 @Override 
 protected void doPost(HttpServletRequest req, HttpServletResponse resp) 
  throws ServletException, IOException { 
 req.setCharacterEncoding("utf-8"); 
 resp.setCharacterEncoding("utf-8"); 
 SmartUpload su = new SmartUpload(); 
 // 由于multipart/form-data的傳輸原因?qū)е聄eq不能使用，所以使用smartupload產(chǎn)生的request 
 Request reqest = su.getRequest(); 
 // 獲得pageContext對象 
 PageContext pageContext = JspFactory.getDefaultFactory() 
  .getPageContext(this, req, resp, null, true, 8192, true); 
 su.initialize(pageContext); 
 try { 
  su.upload(); 
  // 上傳到本項(xiàng)目的upload目錄 
  su.save("upload"); 
 } catch (SmartUploadException e) { 
  e.printStackTrace(); 
 } 
 // 使用smartupload產(chǎn)生的reqest對象來獲得頁面?zhèn)鬟f的參數(shù) 
 String uname = reqest.getParameter("uname"); 
 System.out.println(uname); 
 } 
}

最后說明：使用的組件包為smartupload.zip。
