本文介绍了如何使用maven创建新的项目，并逐步将其转化为符合maven标准的web工程。通过调整目录结构，设置JDK、字符集以及启用Dynamic Web Module，实现了工程的初步构建。接着，作者创建了User类并配置了pom.xml文件，最后展示了index.jsp的设置，完成了基础环境的搭建。

一、创建新的maven项目：

二、目录结构：

完善项目：

首先，完善目录，增加重要的source Folder，这个不是简单的Floder,这些文件夹是会参与编译的。增加src/main/java，src/test/resources，src/test/java目录。让目录变成标准的maven结构。如下图：

接下来，改变一些配置：

让工程的JDK用本地的jdk;

让工程的字符集为UTF-8;

改变工程的目录顺序；

　　这些都完成之后，工程目录应该是如下的样子：

将工程变成web工程

　　此时，我们的工程还不是标准的web工程，可以在eclipse中增加web工程的特性，选择工程的Properties,选Project Facets,如下图：

这里，我们选择Dynamic Web Module,版本选择2.4，这个版本比较通用。结合实际情况调整。如下图：

此时，我们看到目录中多了一个WebContent目录，由于使用maven构建，web目录是src/main/webapp,所以我们删除WebContent目录。接下来，要配置web项目的发布目录，就是Deployment Assembly，如图：

test目录不要发布，WebContent目录没有了，所以这三项都删掉。并且增加src/main/webapp目录，和Maven Dependenices,完成之后如下图：

于是，我们的工程就完全是一个web工程了。

三、建立各个包及类：

User.java

package com.demo.entity;

public class User {
	private Integer id;
	private String userName;
	private String password;
	
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	
}

UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.demo.dao.UserDao">

	<resultMap type="User" id="UserResult">
		<result property="id" column="id"/>
		<result property="userName" column="usermame"/>
		<result property="password" column="password"/>
	</resultMap>
	
	<select id="login" parameterType="User" resultMap="UserResult">
		select * from user where userName=#{userName} and password=#{password}
	</select>

</mapper>

UserDao.java

package com.demo.dao;

import com.demo.entity.User;

public interface UserDao {

	public User login(User user);
}

UserService.java

package com.demo.service;

import com.demo.entity.User;

public interface UserService {

	public User login(User user);
}

UserServiceImpl.java

package com.demo.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.demo.dao.UserDao;
import com.demo.entity.User;
import com.demo.service.UserService;

@Service("userService")
public class UserServiceImpl implements UserService{

	@Resource
	private UserDao userDao;
	
	public User login(User user) {
		return userDao.login(user);
	}

}

UserController.java

package com.demo.controller;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.demo.entity.User;
import com.demo.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController {

	@Resource
	private UserService userService;
	
	@RequestMapping("/login")
	public String login(User user,HttpServletRequest request){
		User resultUser=userService.login(user);
		if(resultUser==null){
			request.setAttribute("user", user);
			request.setAttribute("errorMsg", "用户名或密码错误！");
			return "index";
		}else{
			HttpSession session=request.getSession();
			session.setAttribute("currentUser", resultUser);
			return "redirect:/success.jsp";
		}
	}
	
	@RequestMapping("/upload")
	public String upload(User user,HttpServletRequest request){
		
		return null;
	}
}

四、配置文件：

1、pom.xml
