一、免税店商品代购难点
日本免税店商品（如安耐晒、药妆）需要提供护照信息和离境航班号。北极星日淘支持此类商品的一键代购，自动生成所需材料。
二、用户信息收集组件
<template> <div> <el-form :model="dutyFreeForm"> <el-form-item label="护照号"> <el-input v-model="dutyFreeForm.passportNo"></el-input> </el-form-item> <el-form-item label="离境日期"> <el-date-picker v-model="dutyFreeForm.departureDate"></el-date-picker> </el-form-item> <el-form-item label="航班号"> <el-input v-model="dutyFreeForm.flightNo"></el-input> </el-form-item> </el-form> </div></template>
三、后端生成免税购买凭证
@Servicepublic class DutyFreeService { public String generateCertificate(Long userId, Long productId) { User user = userMapper.selectById(userId); Product product = productMapper.selectById(productId); Map<String, Object> data = new HashMap<>(); data.put("passport", user.getPassportNo()); data.put("departure", user.getDepartureDate()); data.put("product", product.getName()); data.put("quantity", 1); // 生成 PDF 凭证（供日本免税店扫描） byte\[\] pdf = generatePdf("dutyfree_template", data); String url = ossService.upload(pdf, "dutyfree/" + userId + ".pdf"); return url; }}
四、安耐晒等热门商品库存监控
@Componentpublic class AnessaMonitor { @Scheduled(fixedDelay = 1800000) // 30分钟 public void checkStock() { List<String> skus = Arrays.asList("anessa_001", "anessa_002"); for (String sku : skus) { int stock = scrapeStockFromStore(sku); if (stock > 0) { rabbitTemplate.convertAndSend("stock.available", new StockMsg(sku, stock)); } } }}
五、一键代购接口
@PostMapping("/dutyfree/buy")public Result buyDutyFree(@RequestBody DutyFreeBuyReq req) { // 校验用户信息完整性 if (!userService.hasDutyFreeInfo(req.getUserId())) { return Result.error("请先填写护照及航班信息"); } OrderDTO order = new OrderDTO(); order.setUserId(req.getUserId()); order.setProductId(req.getProductId()); order.setSpecialType("DUTY_FREE"); String orderId = orderService.createOrder(order); return Result.success(orderId);}
