insert into order_item (
snapshot_id, order_no,
buy_count, shop_name, spu_id, sku_id,
sku_type, refund_able, auto_approve,
item_title, item_description, unit_price, cost_price,
item_img_url, item_url, sign_key,
project_code, pay_time_limit,product_type,phone_num,created_on,
created_by, updated_on, updated_by, item_belong_user_id,
item_discount_amount,item_member_discount_amount, item_freight_amount, item_electronic_card_amount,
pre_sale, pre_sale_date, item_balance_amount, unit_points, sku_barCode, supplier_id, supplier_name,
stock_date,wx_shop_product_id,wx_shop_sku_id,platform_id,platform_supplier_price,
item_use_integral, item_integral_deduct_amount, business_goods_id, commission_snapshot, ori_unit_price,
ticket_distributor_id, ticket_distributor_name, crossed_price
)
values

#{item.ticketDistributorId}, #{item.ticketDistributorName}, #{item.crossedPrice,jdbcType=DECIMAL}
)

### Expected Behavior

order_item对象的id字段有自增主键的值，现在是null

### Steps To Reproduce

1.插入数据
2.mock数据返回的id值为空

### Anything else
