MyBatis中參數為List

mapper中寫接口，必須加上 @Param("partyOrganId")，否則會出錯。

List<EChartsDO> getMemberByAge(@Param("partyOrganId") List<Long> partyOrganId);

xml映射中：
<sql id="WhereClause">

    where isdel='N'
    <if test="partyOrganId!= null">
        AND party_organ_id in
        <foreach collection="partyOrganId" index="index" item="item" open="(" separator="," close=")">
            #{item}
        </foreach>
    </if>
</sql>

 <select id="getMemberByAge" resultMap="ExtResultMap" parameterType="java.util.List">
select text,count(id) count,total,ROUND(count(id)/total*100,1) percent from
(select case when TIMESTAMPDIFF(YEAR, birthday, CURDATE()) BETWEEN 18 AND 29 then '18-29歲'

when TIMESTAMPDIFF(YEAR, birthday, CURDATE()) >  80 then '80歲以上' end as text,id,
(select count(id) from common_party_member <include refid="WhereClause" />) total
from common_party_member <include refid="WhereClause" />
        )t GROUP BY text
