<sql id="tableName">
    shop
</sql>
<sql id="column">
    shopName,
    shopPrice,
    shopType
</sql>
<sql id="sc">
    #{item.shopName},
    #{item.shopPrice},
    #{item.shopType}
</sql>

<!--mybatis批量添加-->
<insert id="save" parameterType="list" keyProperty="sid" useGeneratedKeys="true"> <!--添加成功返回自增的主键-->
    insert into
    <include refid="tableName"/> <!--表名我这里用的是sql标签-->
    (<include refid="column"/>) <!--添加的字段sql标签-->
    values
    <foreach collection="list" item="item" separator=","> <!--使用了foreach-->
    (<include refid="sc"/>)
    </foreach>
</insert>

<!--批量添加测试-->

//读取配置文件Hui.xml
InputStream config = Resources.getResourceAsStream("config/Hui.xml");
//根据配置文件构建SqlSessionFactory
SqlSessionFactory build = new SqlSessionFactoryBuilder().build(config);
//通过SqlSessionFactory创建SQLSession
SqlSession session = build.openSession();
