@Insert("<script>INSERT INTO scp_activity_gift (activity_id,type,gift_id,status,limit_num,num) "
+ "VALUES "
+" <foreach collection='items' item='item' separator=',' >"
+"(#{item.activityId},#{item.type},#{item.giftId},#{item.status},#{item.limitNum},#{item.num})"
+" </foreach>"
+ "</script>")
@Options(useGeneratedKeys = true, keyProperty = "id")
Integer batchActivityGift(@Param("items")List<ActivityGiftPO> items);
这个会抛异常 Parameter 'id' not found
把 useGeneratedKeys = true 改成 useGeneratedKeys = false

以上问题解决了id not found 然而没有达到我想要的 列表返回主键id
@Insert("<script>INSERT INTO scp_active_offer_category_item (company_item_id,category_id,active_id) "
+ "VALUES "
+" <foreach collection='list' item='item' separator=',' >"
+"(#{item.companyItemId},#{item.categoryId},#{item.activeId})"
+" </foreach>"
+ "</script>")
@Options(useGeneratedKeys = true, keyProperty = "id",keyColumn="id")
Integer batchActiveItem(@Param("list")List<ActiveOfferCategoryItemPO> items);
collection对应的值请使用list
@Param("list")
