mybatis 中where id in ()情况,括号中是list的时候
<select id="selectAll" resultMap="BaseResultMap" > select gc_name_1,gc_id_1,gc_id_2 from order_goods_product <where> gc_id_1 in <foreach collection="list" item="item" index="index" open="(" separator="," close=")"> #{item} </foreach> and ishistory = 0 </where> group by gc_id_1 </select>
其中collerction是指传入数据的类型
