1、用idea创建maven一个项目
此时已经创建好一个maven目录了
2、添加maven依赖
maven依赖代码如下，大致需要的包如下（表较全），根据不同的需求可以添加不同的依赖
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

3、添加表名com.springmvc下的dao,entity,controller,service,及service实现类并创建文件：
实体类：
package com.springmvc.entity;import java.io.Serializable;public class User implements Serializable {private static final long serialVersionUID = 1L;/**用户ID*/private String id;/**用户名*/private String username;/**密码*/private String password;/**姓名*/private String sex;public User() {}public User(String id, String username, String password, String sex) {this.id = id;this.username = username;this.password = password;this.sex = sex;}public String getId() {return id;}public void setId(String 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;}public String getSex() {return sex;}public void setSex(String name) {this.sex = sex;}@Overridepublic String toString() {return "User{" +"id='" + id + '\'' +", username='" + username + '\'' +", password='" + password + '\'' +", sex='" + sex + '\'' +'}';}}
dao接口：
package com.springmvc.dao;import com.springmvc.entity.User;import org.apache.ibatis.annotations.Param;import org.springframework.stereotype.Repository;import java.util.List;@Repository("UserDao")public interface UserDao {/*** Created by JackRen on 2019-04-15* 根据用户名和密码查询用户* @param username* @param password* @return*/public User findByUsernameAndPwd(@Param("username") String username, @Param("password") String password);/*** Created by JackRen on 2019-04-15* 获取用户* @return*/public List<User> find(User User);/*** Created by JackRen on 2019-04-15* 新增* @param User*/public void add(User User);/*** Created by JackRen on 2019-04-15* 修改* @param User*/public void update(User User);/*** Created by JackRen on 2019-04-15* 删除* @param id*/public void delete(String id);}
mapper配置文件：
<?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.springmvc.dao.UserDao"><parameterMap id="parameterMap" type="com.springmvc.entity.User"></parameterMap><resultMap id="resultMap" type="com.springmvc.entity.User"><result property="id" column="id"/><result property="username" column="username"/><result property="password" column="password"/><result property="sex" column="sex"/></resultMap><sql id="columnSql"><trim suffixOverrides=",">t.id,t.username,t.password,t.sex,</trim></sql><select id="findByUsernameAndPwd" resultMap="resultMap">SELECT<include refid="columnSql"></include>FROM t_user tWHERE t.username = #{username} and t.password = #{password}</select></mapper>
service接口：
package com.springmvc.service;import com.springmvc.entity.User;import org.apache.ibatis.annotations.Param;import java.util.List;public interface UserService {/*** Created by JackRen on 2019-04-15* 根据用户名和密码查询用户* @param username* @param password* @return*/public User findByUsernameAndPwd(@Param("username") String username, @Param("password") String password);/*** Created by JackRen on 2019-04-15* 获取用户* @return*/public List<User> find(User User);/*** Created by JackRen on 2019-04-15* 新增* @param User*/public void add(User User);/*** Created by JackRen on 2019-04-15* 修改* @param User*/public void update(User User);/*** Created by JackRen on 2019-04-15* 删除* @param id*/public void delete(String id);}
service实现类：
package com.springmvc.service.impl;import com.springmvc.dao.UserDao;import com.springmvc.entity.User;import com.springmvc.service.UserService;import org.springframework.stereotype.Service;import javax.annotation.Resource;import java.util.List;@Service("UserService")public class UserServiceImpl implements UserService {@Resource(name = "UserDao")private UserDao userDao;public User findByUsernameAndPwd(String name, String pwd) {return userDao.findByUsernameAndPwd(name, pwd);}public List<User> find(User user){return userDao.find(user);}public void add(User user) {userDao.add(user);}public void update(User user) {userDao.update(user);}public void delete(String id) {userDao.delete(id);}}
controller控制器：
package com.springmvc.controller;import com.springmvc.entity.User;import com.springmvc.service.UserService;import org.apache.commons.collections.map.HashedMap;import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import java.util.Map;@Controller@RequestMapping("/user")public class ViewController {private Logger logger = Logger.getLogger(ViewController.class);@Resource(name = "UserService")private UserService userService;@RequestMapping("/index")public String index(){return "index";}@RequestMapping("/find")@ResponseBodypublic Map<String,Object> find(User user, HttpServletRequest request){Map<String,Object> map = new HashedMap();System.out.println("你已通过springMVC进入controller方法。。。。");logger.info("你已通过springMVC进入controller方法。。。。");User loginuser = userService.findByUsernameAndPwd(user.getUsername(),user.getPassword());if(loginuser != null){map.put("result","success");}else {map.put("result","fail");}return map;}@RequestMapping("/success")public String success(){System.out.println("登录成功。。。。");logger.info("登录成功。。。。");return "success";}}
配置resources文件：
dbconfig.properties文件：
#MySQLjdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/db_maven?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=truejdbc.username=rootjdbc.password=admin#oracle#jdbc.driver=oracle.jdbc.driver.OracleDriver#jdbc.url=jdbc:oracle:thin:@localhost:3306:test#jdbc.username=root#jdbc.password=123456
创建数据库表语句：
SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for `t_user`-- ----------------------------DROP TABLE IF EXISTS `t_user`;CREATE TABLE `t_user` (`id` varchar(11) NOT NULL,`username` varchar(40) NOT NULL,`password` varchar(40) NOT NULL,`sex` varchar(4) NOT NULL,PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- ------------------------------ Records of t_user-- ----------------------------INSERT INTO `t_user` VALUES ('1', 'user', '123', '男');
log4j.properties文件：
#日志输出级别log4j.rootLogger=debug,stdout,D,E#设置stdout的日志输出控制台log4j.appender.stdout=org.apache.log4j.ConsoleAppender#输出日志到控制台的方式，默认为System.outlog4j.appender.stdout.Target = System.out#设置使用灵活布局log4j.appender.stdout.layout=org.apache.log4j.PatternLayout#灵活定义输出格式log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%c (%rms)] - %m%n#每天产生一个日志文件log4j.appender.D=org.apache.log4j.DailyRollingFileAppender#设置的输出日志log4j.appender.D.File=F:/persona_project/springmvc/src/main/webapp/WEB-INF/logs/all/log.txt#设置的日志最大限制log4j.appender.D.MaxFileSize=6000KB#最多只保存20个备份文件log4j.appender.D.MaxBackupIndex=20#输出INFO级别以上的日志og4j.appender.D.Threshold=debuglog4j.appender.D.Append = truelog4j.appender.D.ImmediateFlush = true#log4j.appender.D.DatePattern ='.'yyyy-MM-dd#设置使用灵活布局log4j.appender.D.layout=org.apache.log4j.PatternLayout#灵活定义输出格式log4j.appender.D.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%l (%rms)] - %m%nlog4j.appender.E = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.E.File =F:/persona_project/springmvc/src/main/webapp/WEB-INF/logs/error/error.txtlog4j.appender.E.Append = truelog4j.appender.E.Threshold = ERROR#log4j.appender.E.DatePattern = '_'yyyyMMdd'.log'log4j.appender.E.layout = org.apache.log4j.PatternLayoutlog4j.appender.E.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%l (%rms)] - %m%n

4、配置tomcat
5、接下来创建静态资源文件
6、配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" ><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>Manager</display-name><context-param><description>配置Spring配置文件路径</description><param-name>contextConfigLocation</param-name><!-- 如果是监听多个文件，可用‘，’隔开 --><param-value>classpath*:spring-*.xml</param-value></context-param><listener><description>配置Spring上下文监听器</description><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><description>Introspector缓存清除监听器</description><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><listener><description>request监听器</description><listener-class>org.springframework.web.context.request.RequestContextListener</listener-class></listener><!-- 配置Spring字符编码过滤器 --><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--log4j配置文件加载--><context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j.properties</param-value></context-param><!--启动一个watchdog线程每1800秒扫描一下log4j配置文件的变化--><context-param><param-name>log4jRefreshInterval</param-name><param-value>1800000</param-value></context-param><!--spring log4j监听器--><listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class></listener><!-- Spring MVC 核心控制器 DispatcherServlet 配置开始 --><servlet><servlet-name>SpringMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 可以通过contextConfigLocation来自定义SpringMVC配置文件的位置，如不指定，则默认在WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，此时文件名必须为[<servlet-name>]-servlet.xml，否则会出错--><!--以下init-param是自定义SpringMVC的配置文件的位置 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><!-- 拦截设置 --><servlet-mapping><servlet-name>SpringMVC</servlet-name><!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --><url-pattern>/</url-pattern></servlet-mapping><!-- Spring MVC 核心配置结束 --><!-- **Tomcat的defaultServlet来处理静态文件 --><servlet-mapping><servlet-name>default</servlet-name><url-pattern>/static/*</url-pattern></servlet-mapping><!-- session 时间 --><session-config><session-timeout>30</session-timeout></session-config></web-app>
7、在WEB-INF下创建文件夹page，主要放jsp文件
8、index文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head><title>IDEA搭建SpringMVC并用maven配置的小例子</title></head><%--<link rel="stylesheet" href="/asset/css/style.css"/>--%><script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script><body><form id="userForm" action="/user/find" method="post">用户名：<input type="text" name="username"><br>密码：<input type="password" name="password"><button type="button" onclick="login()">登录</button></form></body><script>function login() {$.ajax({type: 'post',url: $('#userForm').attr('action'),data: $('#userForm').serialize(),dataType: 'json',success: function(data){if (data.result = "success"){alert("登录成功");location.href='/user/success';}else{alert("用户名或者密码错误！");}}});}</script></html>
项目结构大致如下：
然后运行tomcat成功之后
在浏览器输入http://localhost:8080/user/index有如下结果：
输入用户名user和密码123就会跳转至登录成功的页面
到此项目搭建完成，可能你们实现的时候因为版本问题会出现很多问题，可以谷歌解决
