Dao层​

public interface TTTDao {

    //查询所有

    List<TTT11> selectAll();

    //插入

    int insert(TTT11 ttt11);

    //通过id删除

    int deleteById(int id);

    //更新

    int update(TTT11 ttt11);

}

myabtis-Mapper配置文件

手牵手入门Spring6整合Mybatis3.5_spring_04

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE mapper

        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

        "https://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.bank.dao.TTTDao">

    <select id="selectAll" resultType="com.bank.object.TTT11">

        select id,name,address from TTT11

    </select>
    <insert id="insert">

        insert into TTT11 values(#{id},#{name},#{address})

    </insert>
    <delete id="deleteById" >

        delete from TTT11 where id = #{id}

    </delete>
    <update id="update">

        update TTT11 set address =#{address} where id=#{id}

    </update>

</mapper>

编写jdbc.properties文件和Mybatis.xml核心配置文件

jdbc.properties


手牵手入门Spring6整合Mybatis3.5_xml_05

jdbc.driver=com.mysql.cj.jdbc.Driver

jdbc.url=jdbc:mysql://IP:3306/mysql?

jdbc.user= root

jdbc.password= 111111

Mybatis.xml主配置文件

手牵手入门Spring6整合Mybatis3.5_bc_06

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE configuration

        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

        "https://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <!--settings控制mybatis全局行为-->

    <settings>

        <!-- logImpl设置mybatis输出日志-->

        <setting name="logImpl" value="STDOUT_LOGGING"/>

    </settings>
</configuration>

Service接口和serviceimp

手牵手入门Spring6整合Mybatis3.5_bc_07

接口

public interface TTTService {
    int save(TTT11 ttt11);

    int delecyById(int id);

    List<TTT11> selectAll();

    int update(TTT11 ttt11);

}

 

实现类​

@Transactional

@Service("tTTService")

public class TTTServiceimpl implements TTTService {
    @Resource

    private TTTDao tttDao;
    @Override

    public int save(TTT11 ttt11) {

        return tttDao.insert(ttt11);

    }
    @Override

    public int delecyById(int id) {

        return tttDao.deleteById(id);

    }
    @Override

    public List<TTT11> selectAll() {

        return tttDao.selectAll();

    }
    @Override

    public int update(TTT11 ttt11) {

        return tttDao.update(ttt11);

    }

}
