  3. Maven资源过滤

    <build>
   <resources>
       <resource>
           <directory>src/main/java</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
       <resource>
           <directory>src/main/resources</directory>
           <includes>
               <include>**/*.properties</include>
               <include>**/*.xml</include>
           </includes>
           <filtering>false</filtering>
       </resource>
   </resources>
</build>

  4. 建立基本结构框架 （如上所示[点此跳转](# 环境配置)

  5. 建立基本配置

    • mybatis-config.xml

      <?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

    • applicationContext.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"
     xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

  6. Mybatis层编写

    • 数据库配置文件 database.properties

      jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456IDEA关联数据库

    • IDEA关联数据库

    • 编写MyBatis的核心配置文件

      <?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
   
   <typeAliases>
       <package name="com.kuang.pojo"/>
   </typeAliases>
   <mappers>
       <mapper resource="com/kuang/dao/BookMapper.xml"/>
   </mappers>

</configuration>

POJO Mapper Services的编写

POJO

  1. User

    @Data  //使用lombok插件即可省写get set
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String username;
    private String password;
    private String name;
    private String sex;
    private String telephone;
    private int age;
    private String begintime;
    private String endtime;
    private int remainday;
    private int addday;

    public static void main(String[] args) {
        User u = new User();
        u.getTelephone();
    }
}

  2. Admin

    @Data
@NoArgsConstructor
@AllArgsConstructor
public class Admin {
    private int id;
    private String username;
    private String password;
    private String name;
    private String telephone;
}

Mapper

  1. 编写DAO层的Mapper接口

    1. 1 userMapper
    public interface UserMapper {
    //通过id查询
    User queryUserById(int id);
//    查询到期时间
    Date queryDateById(int id);
    //修改账号密码
    int updateNP(User user);
    //login
    User userLogin(User user);
    //会员注册
    int userRegister(User user);
}

    1. 2 adminMapper

      @Mapper
@Component
public interface AdminMapper{
    //查询会员
    List<User> queryUser();
    //新增会员
    int addUser(User user);
    //删除会员
    int deleteUserById(int id);
    //更新会员
    int updateUser(User user);
    //根据id查询一个会员
    User queryUserById(int id);
    //根据姓名查询一个会员
    User queryUserByName(String name);
    //login
    Admin adminLogin(Admin admin);
    //查询用户总数
    int selectTotal();
    //    分页
    @Select("select * from gymms.user")
    @Results({
            // 用户信息，只要指定id列与属性的映射关系，其他列会自动封装（属性与列一致）
            @Result(property = "id", column = "id"),
            // 信息
            @Result(property = "id", column = "id"),
            @Result(property = "username", column = "username"),
            @Result(property = "password", column = "password"),
            @Result(property = "name", column = "name"),
            @Result(property = "sex", column = "sex"),
            @Result(property = "telephone", column = "telephone"),
            @Result(property = "age", column = "age"),
            @Result(property = "begintime", column = "begintime"),
            @Result(property = "endtime", column = "endtime"),
            @Result(property = "remainday", column = "remainday")
    })
    List<User> findAll();
}

  2. 编写接口对应的 Mapper.xml 文件

    1. 1 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.cc.dao.UserMapper">
    <select id="queryDate" resultType="User">
        select remainday from gymms.user
      where id = #{id}
    </select>
<!--    查询用户-->
    <select id="queryUserById" resultType="User">
        select * from gymms.user
      where id = #{id}
    </select>
    <!--更新User-->
    <update id="updateUser" parameterType="User">
      update gymms.user
      set username = #{username},password = #{password}
      where id = #{id}
   </update>
    <!--根据账号密码查询,返回一个User-->
    <select id="userLogin" resultType="User">
        select * from gymms.user
      where username = #{username} and password = #{password}
    </select>
<!--    会员注册-->
    <!--增加一个会员-->
    <insert id="userRegister" parameterType="User">
      insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)
      values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})
   </insert>
</mapper>
    1. 2 adminMapper.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.cc.dao.AdminMapper">
    <!--增加一个会员-->
    <insert id="addUser" parameterType="User">
      insert into gymms.user(username,password,name,sex,telephone,age,begintime,endtime,remainday)
      values (#{username},#{password},#{name},#{sex},#{telephone},#{age},#{begintime},#{endtime},#{remainday})
   </insert>
    <!--根据id删除一个User-->
    <delete id="deleteUserById" parameterType="int">
      delete from gymms.user where id=#{id}
   </delete>
    <!--更新User-->
    <update id="updateUser" parameterType="User">
      update gymms.user
      set username = #{username},password = #{password},name = #{name},sex = #{sex},telephone = #{telephone},
      age = #{age},endtime = #{endtime},remainday = #{remainday}
      where id = #{id}
   </update>
    <!--根据id查询,返回一个User-->
    <select id="queryUserById" resultType="User">
      select * from gymms.user
      where id = #{id}
   </select>
    <!--根据姓名查询,返回一个User-->
    <select id="queryUserByName" resultType="User">
      select * from gymms.user
      where name = #{name}
   </select>
    <!--查询全部Book-->
    <select id="queryUser" resultType="User">
      SELECT * from gymms.user
   </select>
    <!--根据账号密码查询,返回一个Admin-->
    <select id="adminLogin" resultType="Admin">
        select * from gymms.admin
      where username = #{username} and password = #{password}
    </select>
    <select id="selectTotal" resultType="int">
        select count(*) from gymms.user
    </select>
</mapper>

  3. 编写Service层的接口和实现类

    1. 1 userService
    public interface UserService {
    //    查询到期时间
    Date queryDateById(int id);
    //修改账号密码
    int updateNP(User user);
    //login
    User userLogin(User user);
    //通过id查询
    User queryUserById(int id);
    //会员注册
    int userRegister(User user);
}
    1. 2 adminService
    public interface AdminService {
    //查询会员
    List<User> queryUser();
    //新增会员
    int addUser(User user);
    //删除会员
    int deleteUserById(int id);
    //更新会员
    int updateUser(User user);
    //根据id查询一个会员
    User queryUserById(int id);
    //根据姓名查询一个会员
    User queryUserByName(String name);
    //login
    Admin adminLogin(Admin admin);
    //查询用户总数
    int selectTotal();
    //    分页
    List<User> findAll();

    /**
     * 分页查询
     * @param pageNum  当然页
     * @param pageSize 页大小
     * @return 返回PageHelper提供的封装分页参数的PageInfo对象
     */
    PageInfo<User> findByPage(int pageNum, int pageSize);
}
    1. 3 userServiceImpl
    public class UserServiceImpl implements UserService {
    private UserMapper userMapper;
    public void setUserMapper(UserMapper userMapper) {
        this.userMapper = userMapper;
    }
    public Date queryDateById(int id) {
        return userMapper.queryDateById(id);
    }
    public int updateNP(User user) {
        return userMapper.updateNP(user);
    }
    public User userLogin(User user) {
        return userMapper.userLogin(user);
    }
    public User queryUserById(int id) {
        return userMapper.queryUserById(id);
    }
    public int userRegister(User user) {
        return userMapper.userRegister(user);
    }
}
    1. 4 adminServiceImpl
    public class AdminServiceImpl implements AdminService {
    private AdminMapper adminMapper;
    public void setAdminMapper(AdminMapper adminMapper) {
        this.adminMapper = adminMapper;
    }
    public List<User> queryUser() {
        return adminMapper.queryUser();
    }
    public int addUser(User user) {
        return adminMapper.addUser(user);
    }
    public int deleteUserById(int id) {
        return adminMapper.deleteUserById(id);
    }
    public int updateUser(User user) {
        return adminMapper.updateUser(user);
    }
    public User queryUserById(int id) { 
        return adminMapper.queryUserById(id); 
    }
    public User queryUserByName(String name) { 
        return adminMapper.queryUserByName(name); 
    }
    public Admin adminLogin(Admin admin) {
        return adminMapper.adminLogin(admin);
    }
    public int selectTotal() {
        return adminMapper.selectTotal();
    }
    public List<User> findAll() {
        return adminMapper.findAll();
    }
    public PageInfo<User> findByPage(int pageNum, int pageSize) {
        PageHelper.startPage(pageNum, pageSize);
        List<User> list = adminMapper.findAll();
        PageInfo<User> pageInfo = new PageInfo<>(list);
        return pageInfo;
    }
}

Spring层

  • 配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；

  • 编写Spring整合Mybatis的相关的配置文件；

结束与总结

这个小Demo做了五六天,分页那里卡了接近两天，无数的坑等着踩。

期间也体会到了编程的乐趣，每天晚上都肝的快快乐乐。

所有代码放在GitHub供大家交流学习。

今天母亲节呀，祝我妈妈母亲节快乐！ 晚安！
