Maven+SpringMvc4+MyBatis+Jdk8+整合ssm架构

女爷i 2022-05-20 09:11 92阅读 0赞

这篇文章的ssm架构事务是xml形式的，其实都是差不多，其实公司用注解事务更多一些，因为容易控制。

代码我也是放在git上面了。

如果你不想看文章，可以直接下载源码浏览，

1、https://gitee.com/redpigstu/ssm\_demo\_xml

2、[https://gitee.com/imjcoder/ssm\_demo\_interface][https_gitee.com_imjcoder_ssm_demo_interface]

1、在eclipse中新建maven项目  
新建完你的项目如图：

![SouthEast][]

这时候java、test都没有，需要简单配置下，右击项目选择最后一个属性：

做一些配置

![SouthEast 1][]![SouthEast 2][]![SouthEast 3][]

之后你的项目会如下图：

![SouthEast 4][]

2、下面开始配置把相关的pom里面的依赖加进来

1.  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

8、新建表t\_user

1.  CREATE TABLE \`t\_user\` (
2.  \`username\` varchar( 255) NOT NULL,
3.  \`password\` varchar( 255) DEFAULT NULL,
4.  PRIMARY KEY ( \`username\`)
5.  ) ENGINE= InnoDB DEFAULT CHARSET=utf8;

9、新建实体类User

1.  package com.entity;
2.  
3.  public class User\{
4.  private String username;
5.  private String password;
6.  public String getUsername()\{
7.  return username;
8.  \}
9.  public void setUsername(String username)\{
10. this.username = username;
11. \}
12. public String getPassword()\{
13. return password;
14. \}
15. public void setPassword(String password)\{
16. this.password = password;
17. \}
18. 
19. \}

10、新建mybatis mapper配置文件UserMapper.xml

1.  <?xml version="1.0" encoding="UTF-8" ?>
2.  <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
3.  <mapper namespace="com.dao.UserDao">
4.  <resultMap id="BaseResultMap" type="com.entity.User">
5.  <result column="username" property="username" />
6.  <result column="password" property="password" />
7.  </resultMap>
8.  <sql id="Base\_Column\_List" >
9.  username, password
10. </sql>
11. <select id="selectId" resultMap="BaseResultMap" parameterType="java.lang.String" >
12. select
13. <include refid="Base\_Column\_List" />
14. from t\_user
15. where username = \#\{username,jdbcType=VARCHAR\}
16. </select>
17. </mapper>

11、创建service接口

1.  package com.service;
2.  
3.  import org.springframework.stereotype.Service;
4.  
5.  import com.entity.User;
6.  
7.  @Service
8.  public interface UserService\{
9.  boolean doUserLogin(User user);
10. 
11. \}

12、创建service实现类

1.  package com.service;
2.  
3.  import java.util.List;
4.  
5.  import javax.annotation.Resource;
6.  import javax.annotation.Resources;
7.  
8.  import org.springframework.stereotype.Service;
9.  
10. import com.dao.UserDao;
11. import com.entity.User;
12. 
13. @Service
14. public class UserServiceImpl implements UserService\{
15. 
16. @Resource
17. private UserDao userDao;
18. 
19. public boolean doUserLogin(User user)\{
20. List<User> list = userDao.selectId(user.getUsername());
21. if(list.size() == 0)\{
22. return false;
23. \} else\{
24. if(list.get( 0).getPassword().equals(user.getPassword()))\{
25. return true;
26. \} else\{
27. return false;
28. \}
29. \}
30. \}
31. 
32. \}

13、创建UserDao接口

1.  package com.dao;
2.  
3.  import java.util.List;
4.  
5.  import org.springframework.stereotype.Repository;
6.  
7.  import com.entity.User;
8.  
9.  @Repository
10. public interface UserDao\{
11. List<User> selectId(String username);
12. \}

14、创建controller

1.  package com.controller;
2.  
3.  import org.springframework.beans.factory.annotation.Autowired;
4.  import org.springframework.stereotype.Controller;
5.  import org.springframework.ui.Model;
6.  import org.springframework.web.bind.annotation.RequestMapping;
7.  
8.  import com.entity.User;
9.  import com.service.UserService;
10. 
11. @Controller
12. @RequestMapping( "/test")
13. */\*@ResponseBody \*/*
14. public class LoginController\{
15. @Autowired
16. private UserService userService; *//基于接口的,用接口接收*
17. 
18. @RequestMapping( "/login.action") *//url* 
19. public String dologin(User user, Model model)\{
20. if(userService.doUserLogin(user))\{
21. System.out.println(user);
22. model.addAttribute( "successMsg", "登陆成功！"); *//返回到页面所夹带的参数* 
23. model.addAttribute( "name", user.getUsername());
24. return "/success"; *//返回的页面* 
25. \} else\{
26. model.addAttribute( "failMsg", "用户不存在或密码错误！");
27. return "/fail";
28. \}
29. \}
30. 
31. 
32. 
33. \}
