Mapper Files

Mapper XML in other-module

other-module/src/main/resources/com/example/demo/FooMapper.xml

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.demo.FooMapper">
    <select id="ping" resultType="_int">
        select 1
    </select>
</mapper>

Note: return 1 from other module mapper file.

Mapper XML in my-module (overriding mapper xml)

my-module/src/main/resources/com/example/demo/FooMapper.xml

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.demo.FooMapper">
    <select id="ping" resultType="_int">
        select 2
    </select>
</mapper>

Note: return 2 from my module mapper file.
