Mybatis ResultMap Collection 複合主鍵

 <resultMap type="XX" id="XXMap">  
        <id property="id" column="colid"/>  

        <id property="name" column="colname"/>  

        <collection property="list" javaType="ArrayList" column="{id = colid,name=colname}" select="getSubXXX"/>
 </resultMap> 

前爲別名後爲主查詢getXXX語句中字段

<select id="getXXX" parameterType="HashMap" resultMap="XXX">  
        SELECT colid,colname FROM table1

 </select> 

 <select id="getSubXXX" parameterType="HashMap" resultType="XXX">  
        SELECT * FROM table2 WHERE id = #{id} AND name = #{name}
  </select>
