MyBatis定义复合主键

<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>

前为别名后为主查询getXXX语句中字段

<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>
