mybatis的association传递参数问题示例

<resultMap id="stationVo" type="com.gt.dev.domain.vo.DevStationVO" extends="station">
        <result property="distance" column="distance"/>
        <association property="on" column="{stationId=id,state=on}"
                     select="com.gt.dev.mapper.DevInfoMapper.countByStationId"/>
        <association property="off" column="{stationId=id,state=off}"
                     select="com.gt.dev.mapper.DevInfoMapper.countByStationId"/>
        <association property="error" column="{stationId=id,state=error}"
                     select="com.gt.dev.mapper.DevInfoMapper.countByStationId"/>
    </resultMap>

<association column="id" property="User" select="getUser"></association>

<select id="getUser" resultMap="UserMap" parameterType="java.lang.String">
    SELECT * FROM user_table WHERE id = #{id}
</select>

<association column="{param1=id,param2=name}" property="User" select="getUser"></association>

<select id="getUser" resultMap="UserMap" parameterType="java.util.Map">
    SELECT * FROM user_table WHERE id = #{param1} and name = #{param2}
</select>
