SSM框架整合
1、创建数据库
create DATABASE 'laydata';
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int NOT NULL AUTO_INCREMENT,
`username` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL,
`phone` varchar(20) DEFAULT NULL,
`sex` char(5) DEFAULT NULL,
`email` varchar(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', 'Yuriki', '123456', '123456799', 'girl', '1574900639@qq.com');
INSERT INTO `user` VALUES ('2', 'sendCode', '123456', '15580542077', 'Ů', 'dsfsdfsdfd');
INSERT INTO `user` VALUES ('3', 'sendeedee', 'sdf', null, null, null);
INSERT INTO `user` VALUES ('4', '123', '1234333', '15580542077', 'Ů', 'sfdsfsdfsdf');
INSERT INTO `user` VALUES ('5', '1', '1', '1', '男', '1');
INSERT INTO `user` VALUES ('6', '2', '2', '2', '男', '2');
INSERT INTO `user` VALUES ('7', '小经', 'test2', '15580542077', '女', 'test2');
INSERT INTO `user` VALUES ('16', 'll', 'bb', 'cc', null, '90');
INSERT INTO `user` VALUES ('17', 'Yuriki', 'sdfds', null, '男', null);
INSERT INTO `user` VALUES ('18', 'aa', 'bb', 'cc', '男', 'dd');
INSERT INTO `user` VALUES ('19', 'Yuriki', 'sdfds', '1334545', '女', '454354@qq.com');
INSERT INTO `user` VALUES ('20', 'Yuriki', 'sdfds', 'sd', 'sdf', 'sdf');
INSERT INTO `user` VALUES ('90', 'sdf', 'sdf', 'sdf', 'sdf', 'sdf');
INSERT INTO `user` VALUES ('93', '123', 'wrewr', 'sdf', 'sfsdf', 'sdfsdf');
INSERT INTO `user` VALUES ('94', '123', 'wrewr', 'sdf', 'sfsdf', 'sdfsdf');
2、导入pom依赖

4、基本框架
4.1、实体类
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String username;
private String password;
private String phone;
private String sex;
private String email;
}
4.2、dao层
4.2.1、接口文件
public interface UserMapper {
void addUser(User user);
void delUser(int id);
void upUser(User user);
List<User> selectAll();
User selectUserById(int id);
}
4.2.2、映射文件
UserMapper.xml
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.Yu.dao.UserMapper">
<insert id="addUser" parameterType="User">
insert into user(username,password,phone,sex,email) values(#{username},#{password},#{phone},#{sex},#{email})
</insert>
<delete id="delUser" parameterType="int">
delete from user where id=#{id}
</delete>
<update id="upUser" parameterType="User">
update user
set username=#{username},password=#{password},phone=#{phone},sex=#{sex},email=#{email}
where id=#{id}
</update>
<select id="selectAll" resultType="User">
select * from user
</select>
<select id="selectUserById" parameterType="int" resultType="User">
select * from user where id=#{id}
</select>
</mapper>
4.3、业务层
4.3.1、接口
public interface UserService {
void addUser(User user);
void delUser(int id);
void upUser(User user);
List<User> selectAll();
User selectUserById(int id);
}
4.3.2、实现类
public class UserServiceImpl implements UserService{
private UserMapper userMapper;
public void setUserMapper(UserMapper userMapper) {
this.userMapper = userMapper;
}
@Override
public void addUser(User user) {
userMapper.addUser(user);
}
@Override
public void delUser(int id) {
userMapper.delUser(id);
}
@Override
public void upUser(User user) {
userMapper.upUser(user);
}
@Override
public List<User> selectAll() {
return userMapper.selectAll();
}
@Override
public User selectUserById(int id) {
return userMapper.selectUserById(id);
}
}
4.4、配置文件
数据库配置文件
# db.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/laydata
jdbc.username=root
jdbc.password=123456
mybatis核心配置文件
mybatis-config.xml
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--起别名,在映射文件中需要写全限定名的地方就可以省略包名了-->
<typeAliases>
<package name="com.Yu.po"/>
</typeAliases>
<!--添加映射文件-->
<mappers>
<mapper resource="com/Yu/dao/UserMapper.xml"/>
</mappers>
</configuration>
