為了使用Mybatis進行持久化操作，通常有如下操作步驟：

• 開發持久化類PO和編寫持久化操作的Mapper.xml, 在其中定義要執行的SQL語句
• 獲取SqlSessionFactory
• 獲取SqlSession
• 用面向物件的方式操作資料庫
• 關閉事務，關閉SqlSession

Mapper.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="org.tsui.mapper.UserMapper" >
    <insert id="save" parameterType="org.tsui.domain.User" useGeneratedKeys="true">
        INSERT INTO tb_user(name, sex, age) VALUES(#{name}, #{sex}, #{age})
    </insert>
</mapper>

MyBatis的配置檔案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>
    <settings>
        <setting name="logImpl" value="LOG4J"/>
    </settings>
    <environments default="mysql">
        <environment
 
 id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://127.0.0.1:3306/mybatis"/>
                <property name="username" value="root"/>
                <property name="password" value="123456"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper resource="org/tsui/mapper/UserMapper.xml"/>
    </mappers>
</configuration>

測試程式碼

package org.tsui.tst;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.tsui.domain.User;

import java.io.IOException;
import java.io.InputStream;

public class MybatisTest {
    public static void main(String[] args) throws IOException {
        //讀取mybatis-config.xml檔案
        InputStream is = Resources.getResourceAsStream("mybatis-config.xml");
        //初始化mybatis，建立SqlSessionFactory例項
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(is);
        //建立Session例項
        SqlSession session = factory.openSession();

        //建立User物件
        User user = new User();
        user.setName("cuiyunhong");
        user.setAge(22);
        user.setSex("男");

        //插入資料
        session.insert("org.tsui.mapper.UserMapper.save", user);
        //提交事務
        session.commit();
        //關閉session
        session.close();
    }

}
