mybatis 傳入list 循環

  SELECT * from lp_customer_info where 1=1
        <if test="ids.size() > 0">
            and id in
            <foreach item="item" index="index" collection="ids" open="(" separator="," close=")">
                #{item}
            </foreach>
        </if>

 IPage<QueryDeliveryPeopleDTO> queryDeliveryPeopleList(Page page, @Param("ids") List<Long> ids);

傳入的 類型要爲 list ，  要是傳入set 集合  會有問題
