+## shop-api 后端秒杀模块实现
+- **项目路径**: `/Users/gxwebsoft/JAVA/shop-api`
+- 新增完整的秒杀后端模块，参考 ShopGoods 四层架构模板
+- **Entity**: ShopSeckill.java + ShopSeckillOrder.java（含 tenantId 多租户）
+- **Param**: ShopSeckillParam.java
+- **Mapper**: ShopSeckillMapper + ShopSeckillOrderMapper + XML（含原子扣库存 SQL）
+- **Service**: ShopSeckillServiceImpl（核心下单逻辑：防重复提交→活动校验→限购校验→原子扣库存→创建订单→Redis记录已购）
+- **Controller**: ShopSeckillController（管理端 CRUD + 用户端 createOrder/myOrders/timeSlots）
+- **定时任务**: SeckillStatusTask（每60秒自动更新过期秒杀状态）
+- **建表SQL**: src/main/resources/sql/shop_seckill.sql
+- API 路径 `/api/shop/shopSeckill`，与前端 `/shopSeckill/*` 对齐

+### 商品详情页轮播图添加点击放大预览
+- **文件**: `src/pages/shop/product-detail.tsx`
+- 在 Swiper 轮播图的 Image 上添加 `onClick` → 调用 `Taro.previewImage({ current: img, urls: images })`
+- `previewImage` 是 Taro 内置 API，在小程序中原生支持全屏预览 + 左右滑动翻图，无需额外组件
+- **文件**: `src/pages/points/product-detail.tsx` — 同样添加了点击放大预览
