创建公共的.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="???.CommonMapper">
    <resultMap type="java.util.Map" id="attributesCommonMap">
          <id column="???" property="???" jdbcType="VARCHAR"/> 
          <result column="？？？" property="??" jdbcType="BIGINT"/> 
    </resultMap>
</mapper>

引用部分举例

<association property="？？？" javaType="java.util.Map" resultMap="？？？？.CommonMapper.attributesCommonMap" >
 </association>
