3、在WEB-INF文件夹下添加/修改以下配置文件

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-3.1.xsd  http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-3.1.xsd  http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!--避免IE执行AJAX时，返回JSON出现下载文件 --><bean id="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><!-- 添加注解驱动 -->  <mvc:annotation-driven /><mvc:default-servlet-handler/><!-- 设置使用注解的类所在的包 --><context:component-scan base-package="com.chillax.controller" /><!-- 完成请求和注解POJO的映射 --><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --></list></property></bean><!-- 定义跳转的文件的前后缀 ，视图模式配置--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- SpringMVC上传文件时，需要配置MultipartResolver处理器--><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  <!-- 默认编码 --><property name="defaultEncoding" value="utf-8" />  <!-- 文件大小最大值 --><property name="maxUploadSize" value="10485760000" />  <!-- 内存中的最大值 --><property name="maxInMemorySize" value="40960" />  </bean> </beans>

web.xml

4、在src/main/java下添加如下包和类

package com.chillax.controller;import java.util.List;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import com.chillax.dto.User;
import com.chillax.service.IUserService;@Controller
@RequestMapping("/user")
public class UserController {@Resourceprivate IUserService userService;@RequestMapping("/userList")public String userList(HttpServletRequest request,Model model){List<User> uList = userService.getAllUser();model.addAttribute("uList", uList);return "userList";}@RequestMapping("/showUser")public String showUser(HttpServletRequest request,Model model){int userId = Integer.parseInt(request.getParameter("id"));User user = userService.getUserById(userId);model.addAttribute("user", user);return "showUser";}@RequestMapping("/addUserUI")public String addUserUI(){return "addUser";}@RequestMapping("/addUser")public String addUser(HttpServletRequest request,Model model){User user = new User();user.setName(String.valueOf(request.getParameter("name")));user.setPassword(String.valueOf(request.getParameter("password")));user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));userService.addUser(user);return "redirect:/user/userList";}
}

package com.chillax.dao;import java.util.List;
import java.util.Map;import com.chillax.dto.User;public interface IUserDao {public User queryByPrimaryKey(Integer id);public List<User> queryUserByBatch(Map<String,Object> params);public void insertUser(User user);public void insertUserByBatch(List<User> list);public void deleteByPrimaryKey(Integer id);public void delteUserByBatch(Map<String,Object> params);public void updateByPrimaryKey(Integer id);public List<User> getAllUser();}

User.java

package com.chillax.dto;public class User {private Integer id;private String name;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password == null ? null : password.trim();}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}
}

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.chillax.dao.IUserDao" >  <resultMap id="BaseResultMap" type="com.chillax.dto.User"><result column="id" property="id" jdbcType="INTEGER" /><result column="name" property="name" jdbcType="VARCHAR" /><result column="password" property="password" jdbcType="VARCHAR" /><result column="age" property="age" jdbcType="INTEGER" /></resultMap><sql id="Base_Column_List">id, name, password, age</sql><!-- 查询用户--><select id="queryByPrimaryKey" resultMap="BaseResultMap"parameterType="java.lang.Integer">select<include refid="Base_Column_List" />from userwhere id = #{id,jdbcType=INTEGER}</select><!-- 查询用户--><select id="getAllUser" resultMap="BaseResultMap">select<include refid="Base_Column_List" />from user</select><!-- 批量查询用户--><select id="queryUserByBatch" resultMap="BaseResultMap"parameterType="java.util.Map">select<include refid="Base_Column_List" />from userwhere id in<foreach collection="idList" item="userId" index="index" open="(" separator="," close=")">#{userId,jdbcType=DECIMAL}</foreach></select><!-- 插入用户 --><insert id="insertUser" parameterType="com.chillax.dto.User">insert into user  <trim prefix="(" suffix=")" suffixOverrides="," >  <if test="id != null" >  id,  </if>  <if test="name != null" >  name,  </if>  <if test="password != null" >  password,  </if>  <if test="age != null" >  age,  </if>  </trim>  <trim prefix="values (" suffix=")" suffixOverrides="," >  <if test="id != null" >  #{id,jdbcType=INTEGER},  </if>  <if test="name != null" >  #{name,jdbcType=VARCHAR},  </if>  <if test="password != null" >  #{password,jdbcType=VARCHAR},  </if>  <if test="age != null" >  #{age,jdbcType=INTEGER},  </if>  </trim>   </insert><!-- 批量插入用户 --><insert id="insertUserByBatch" parameterType="java.util.List" >insert into USER(ID,NAME,PASSWORD,AGE)select A.* from(<foreach collection="list" item="user" index="index" separator="union">select #{user.id,jdbcType=INTEGER},#{user.name,jdbcType=VARCHAR},#{user.password,jdbcType=VARCHAR},#{user.age,jdbcType=INTEGER}from dual</foreach>) A</insert><!-- 删除用户 --><delete id="deleteByPrimaryKey" parameterType="java.lang.Integer">delete from userwhere id = #{id,jdbcType=INTEGER}  </delete><!-- 批量删除用户 --><delete id="deleteUserByBatch" parameterType="java.util.Map" >delete from userwhere id IN <foreach item="ids" collection="iList" open="(" separator="," close=")">#{ids,jdbcType=DECIMAL}</foreach></delete><!-- 更新用户 --><update id="updateByPrimaryKey" parameterType="com.chillax.dto.User" >  update user  <set >  <if test="name != null" >  name = #{name,jdbcType=VARCHAR},  </if>  <if test="password != null" >  password = #{password,jdbcType=VARCHAR},  </if>  <if test="age != null" >  age = #{age,jdbcType=INTEGER},  </if>  </set>  where id = #{id,jdbcType=INTEGER} </update></mapper>

package com.chillax.service;import java.util.List;import com.chillax.dto.User;public interface IUserService {public User getUserById(int userId);public void insertUser(User user);public void addUser(User user);public List<User> getAllUser();
}

package com.chillax.service.Impl;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.chillax.dao.IUserDao;
import com.chillax.dto.User;
import com.chillax.service.IUserService;@Service("userService")
public class UserServiceImpl implements IUserService {@Resourceprivate IUserDao userDao;public User getUserById(int userId) {return userDao.queryByPrimaryKey(userId);}public void insertUser(User user) {userDao.insertUser(user);}public void addUser(User user) {userDao.insertUser(user);}@Overridepublic List<User> getAllUser() {return userDao.getAllUser();}}

5、在WEB-INF文件夹下创建jsp文件夹，并添加userList.jsp，showUser.jsp、addUser.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head><base href="<%=basePath%>"><title>My JSP 'showUser.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--></head><body><c:forEach items="${uList }" var="u">用户名称：${u.name}用户年龄：${u.age }<br/></c:forEach></body>
</html>

addUser.jsp

<%@ page language="java" import="java.util.*" 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">
<html><head><base href="<%=basePath%>"><title>My JSP 'addUser.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--></head><body><form id="addUser" action="user/addUser" method="post"> userName: <input id="name" name="name" /><br/> password: <input id="password" name="password" /><br/> age: <input id="age" name="age"/><br/> <input type="submit" value="添加新用户"/> </form></body>
</html>

<%@ page language="java" import="java.util.*" 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">
<html><head><base href="<%=basePath%>"><title>My JSP 'showUser.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--></head><body>${user.name }<br></body>
</html>

6、创建数据库，并创建表

DROP TABLE IF EXISTS `user`;CREATE TABLE `user` (`id` int(12) NOT NULL AUTO_INCREMENT,`name` varchar(50) NOT NULL,`password` varchar(50) NOT NULL,`age` int(9) NOT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;insert  into `user`(`id`,`name`,`password`,`age`) values (1,'admin','admin',22);

7、整个项目文件结构图

8、部署发布项目，进行测试

1. <plugins>
2. <plugin>
3. <groupId>org.apache.maven.plugins</groupId>
4. <artifactId>maven-compiler-plugin</artifactId>
5. <version>2.3.2</version>
6. <configuration>
