建立基本结构框架 （如上所示[点此跳转](# 环境配置)

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 "> </beans>

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/> </typeAliases> <mappers> <mapper resource="com/kuang/dao/BookMapper.xml"/> </mappers> </configuration>

POJO Mapper Services的编写 POJO

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(); } }

Admin

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

Mapper

编写DAO层的Mapper接口

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); }
