LD is tigger forever，CG are not brothers forever， throw the pot and shine forever.
Modesty is not false, solid is not naive, treacherous but not deceitful, stay with good people, and stay away from poor people.

下载mybatis 源码
测试问题：
１。生成ｓｑｌ脚本：
create table SomeTable (
id int,
field1 varchar(20),
field2 varchar(20),
field3 varchar(20)
);
２。定义ｍａｐｐｅｒ文件
`
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="org.apache.ibatis.submitted.includes.fragments">
<sql id="select">
select
</sql>
<sql id="update">
update
</sql>
<sql id="values">
VALUES (1);
</sql>
</mapper>`
ｍａｐｐｅｒ 的总配置文件：
<mappers>
<mapper resource="org/apache/ibatis/submitted/includes/Fragments.xml"/>
<mapper resource="org/apache/ibatis/submitted/includes/Mapper.xml"/>
</mappers>
Ｊａｖａ文件：
@Test void testParametrizedIncludes() { try (SqlSession sqlSession = sqlSessionFactory.openSession()) { final Mapｍａｐｐｅｒ：
<sql id="someinclude">
<include refid="${include_target}"/>
</sql>
<select id="select" resultType="map">
<include refid="someinclude">
<property name="include_target" value="org.apache.ibatis.submitted.includes.fragments.select"/>
</include>
field1, field2, field3
from
<include refid="someinclude">
<property name="prefix" value="Some"/>
<property name="include_target" value="sometable"/>
</include>
</select>
也可以在 include 元素的 refid 属性或内部语句中使用属性值，
