1.最终完成的工程架构：
2.下面详细讲解一下
新建Maven项目：点击File -> New -> Project -> Maven -> 勾选 Create from archetype -> 选择 maven-archetype-webapp。
在弹出的new project 选项卡中填写GroupId和Artifactid，自己随便写就是了。
点Next，然后点那三个点，选择自己本地的maven。
然后点那个＋号，Name跟Value跟我的输一样就是了。
然后点OK,Next,Finish。
右下角那个框里点右边那个，然后等到BUILD SUCCESS。
接下来可以在数据库里建表了，类似于下面这张表。
在这之前要对项目的pom.xml文件进行配置，在此文件中配置项目所需要的jar包。
pom.xml

在main下面建两个Directory：分别命名为java，resources。
然后右击，找到Mark Directory as，分别选Source Root，Resources Root。
在刚才新建的java文件下新建“com.zhongruan.bean”包，依次展开，再在zhongruan包下新建三个包，分别命名为：service,dao,controller。
在src下面建一个Directory，命名为target，然后找到Mark Directory as，设置为Excluded。
在bean下面创建类UserInfo,代码如下：
package com.zhongruan.bean;
public class UserInfo {
private int id;
private String username;
private String password;
public int getId() {
return id;
}
public void setId(int 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;
}
@Override
public String toString() {
return "UserInfo{" +
"id=" + id +
", username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}
接下来在dao下面创建接口IUserDao。
package com.zhongruan.dao;
import com.zhongruan.bean.UserInfo;
import java.util.List;
public interface IUserDao {
public List<UserInfo> findAll();
public void insert(UserInfo userInfo);
public void delete(UserInfo userInfo);
public void update(UserInfo userInfo);
public UserInfo findId(int id);
}
在controller下面创建Usercontroller
package com.zhongruan.controller;
import com.zhongruan.bean.UserInfo;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.List;
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private IUserService userService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() {
List<UserInfo> all = userService.findAll();
ModelAndView mv = new ModelAndView();
mv.addObject("userInfos", all);
mv.setViewName("allUser");
return mv;
}
@RequestMapping("/toAddUser.do")
public ModelAndView insert() {
ModelAndView mv = new ModelAndView();
mv.setViewName("addUser");
return mv;
}
@RequestMapping("/save.do")
public ModelAndView save(UserInfo userinfo) {
userService.insert(userinfo);
ModelAndView mv = new ModelAndView();
mv = findAll();
return mv;
}
@RequestMapping("/delete.do")
public ModelAndView delete(UserInfo userinfo) {
userService.delete(userinfo);
ModelAndView mv = new ModelAndView();
mv = findAll();
return mv;
}
@RequestMapping("/toUpdate.do")
public ModelAndView toUpdate(int id) {
ModelAndView mv = new ModelAndView();
mv = findAll();
UserInfo userinfo = userService.findId(id);
mv.addObject("userInfo", userinfo);
mv.setViewName("updateUser");
return mv;
}
@RequestMapping("/update.do")
public ModelAndView update(UserInfo userinfo) {
ModelAndView mv = new ModelAndView();
userService.update(userinfo);
mv = findAll();
return mv;
}
}
在Service下面建接口IUserService:
package com.zhongruan.service;
import com.zhongruan.bean.UserInfo;
import java.util.List;
public interface IUserService {
public List<UserInfo> findAll();
public void insert(UserInfo userinfo);
public void delete(UserInfo userinfo);
public UserInfo findId(int id);
public void update(UserInfo userinfo);
}
在service下面建一个包：impl，在这个包下面创建类：UserService。
package com.zhongruan.service.impl;
import com.zhongruan.bean.UserInfo;
import com.zhongruan.dao.IUserDao;
import com.zhongruan.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserService implements IUserService {
@Autowired
private IUserDao userDao;
@Override
public List<UserInfo> findAll() {
return userDao.findAll();
}
public void insert(UserInfo userinfo){
userDao.insert(userinfo);
}
public void delete(UserInfo userinfo){
userDao.delete(userinfo);
}
public void update(UserInfo userinfo){
userDao.update(userinfo);
}
public UserInfo findId(int id) {
return userDao.findId(id);
}
}
在resources下面建包mapper，然后在这个包下面新建一个UserMapper.xml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.zhongruan.dao.IUserDao" >
<select id="findAll" resultType="com.zhongruan.bean.UserInfo">
select * from userinfo
</select>
<insert id="insert" parameterType="com.zhongruan.bean.UserInfo">
insert into userinfo(id,username,password) values(#{id},#{username},#{password})
</insert>
<delete id="delete" parameterType="com.zhongruan.bean.UserInfo">
delete from userinfo where id =#{id}
</delete>
<update id="update" parameterType="com.zhongruan.bean.UserInfo">
update userinfo set username=#{username},password=#{password} where id=#{id}
</update>
<select id="findid" resultType="com.zhongruan.bean.UserInfo">
select * from userinfo where id=#{id}
</select>
</mapper>
在WEB-INF下面创建文件，如图所示：
addUser：

接下来用tomcat运行。点这个Add Configuration
点加号，进去后选最底下那个33 items more。
然后点 tomcat server -> local 选择下载安装到本地的tomcat服务器的地址
切换到Deployment选项页 点击 + 号选择 Arctifact
添加 项目名:war exploded 打包
最后在Application context 中选择 空白 那一项，点击 Apply 应用。
最后点Run“tomcat7”运行
后面的因为我的MySQL出问题了，连不上本机数据库，所以暂时看不了了。
