这是用的是SpringMVC-3.1.1、commons-fileupload-1.2.2和io-2.0.1

首先是web.xml
[html] < xml version="1.0" encoding="UTF-8" >
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">

upload
org.springframework.web.servlet.DispatcherServlet
1


upload
/



SpringCharacterEncodingFilter
org.springframework.web.filter.CharacterEncodingFilter

encoding
UTF-8



SpringCharacterEncodingFilter
/*



/WEB-INF/jsp/user/add.jsp

接下来是SpringMVC的配置文件upload-servlet.xml
[html]
< xml version="1.0" encoding="UTF-8" >
http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">





















error_fileupload

下面是用于上传的表单页面//WEB-INF//jsp//user//add.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>

下面是上传成功后打印用户信息的页面//WEB-INF//jsp//user//list.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

${user.value.username}----${user.value.nickname}----${user.value.password}----${user.value.email}
查看
编辑
删除





继续添加用户

下面是上传文件内容过大时的提示页面//WEB-INF//jsp//error_fileupload.jsp
[html]
<%@ page language="java" pageEncoding="UTF-8"%>

文件过大，请重新选择

接下来是用到的实体类User.java
[java]
package com.jadyer.model;

/**
* User
* @author 宏宇
* @create May 12, 2012 1:24:43 AM
*/
public class User {
private String username;
private String nickname;
private String password;
private String email;
/*==四个属性的getter()、setter()略==*/
public User() {}
public User(String username, String nickname, String password, String email) {
this.username = username;
this.nickname = nickname;
this.password = password;
this.email = email;
}
}

最后是核心的UserController.java
[java]
package com.jadyer.controller;

import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.io.FileUtils;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.sprin
