以下是一个基于Java的社区团购卖菜卖水果商城自提点商城源码系统的部分代码片段，涵盖用户下单、自提点选择、订单处理等核心功能：

1. 用户下单与自提点选择（Spring Boot Controller层）

java @RestController @RequestMapping("/api/orders") public class OrderController { @Autowired private OrderService orderService; @Autowired private SelfPickupPointService pickupPointService; // 用户下单并选择自提点 @PostMapping("/create") public ResponseEntity<OrderResponse> createOrder( @RequestBody OrderCreateRequest request, @RequestHeader("Authorization") String token) { // 解析JWT令牌获取用户ID Long userId = JwtUtil.parseUserId(token); // 验证自提点是否存在且可用 SelfPickupPoint pickupPoint = pickupPointService.validatePickupPoint(request.getPickupPointId()); if (pickupPoint == null) { throw new RuntimeException("自提点不存在或不可用"); } // 创建订单 Order order = new Order(); order.setUserId(userId); order.setPickupPointId(pickupPoint.getId()); order.setTotalAmount(request.getTotalAmount()); order.setStatus(OrderStatus.PENDING_PAYMENT); // 保存订单 Order savedOrder = orderService.saveOrder(order); // 返回订单信息 return ResponseEntity.ok(new OrderResponse(savedOrder)); } }

2. 自提点管理（Service层）

java @Service public class SelfPickupPointService { @Autowired private SelfPickupPointRepository pickupPointRepository; // 验证自提点是否存在且可用 public SelfPickupPoint validatePickupPoint(Long pickupPointId) { return pickupPointRepository.findByIdAndStatus(pickupPointId, PickupPointStatus.ACTIVE) .orElse(null); } // 添加自提点 public SelfPickupPoint addPickupPoint(SelfPickupPointRequest request) { SelfPickupPoint pickupPoint = new SelfPickupPoint(); pickupPoint.setName(request.getName()); pickupPoint.setAddress(request.getAddress()); pickupPoint.setContactPhone(request.getContactPhone()); pickupPoint.setStatus(PickupPointStatus.ACTIVE); return pickupPointRepository.save(pickupPoint); } // 更新自提点状态（如关闭自提点） public void updatePickupPointStatus(Long pickupPointId, PickupPointStatus status) { SelfPickupPoint pickupPoint = pickupPointRepository.findById(pickupPointId) .orElseThrow(() -> new RuntimeException("自提点不存在")); pickupPoint.setStatus(status); pickupPointRepository.save(pickupPoint); } }

3. 订单处理（Service层）

java @Service public class OrderService { @Autowired private OrderRepository orderRepository; @Autowired private InventoryService inventoryService; // 保存订单 public Order saveOrder(Order order) { // 检查库存是否充足 List<OrderItem> items = order.getItems(); for (OrderItem item : items) { boolean hasEnoughStock = inventoryService.checkStock( item.getProductId(), item.getQuantity() ); if (!hasEnoughStock) { throw new RuntimeException("商品库存不足: " + item.getProductName()); } } // 扣减库存 for (OrderItem item : items) { inventoryService.deductStock( item.getProductId(), item.getQuantity() ); } // 保存订单 return orderRepository.save(order); } // 支付成功后的订单处理 public void processPaymentSuccess(Long orderId) { Order order = orderRepository.findById(orderId) .orElseThrow(() -> new RuntimeException("订单不存在")); if (order.getStatus() != OrderStatus.PENDING_PAYMENT) { throw new RuntimeException("订单状态异常"); } order.setStatus(OrderStatus.PAID); orderRepository.save(order); // 发送提货通知（短信/邮件） sendPickupNotification(order); } // 发送提货通知 private void sendPickupNotification(Order order) { // 实际项目中集成短信/邮件服务 System.out.println("发送提货通知给用户 " + order.getUserId() + ", 自提点: " + order.getPickupPointId()); } }

4. 数据库实体类（Order与SelfPickupPoint）

java @Entity public class Order { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private Long userId; private Long pickupPointId; private BigDecimal totalAmount; @Enumerated(EnumType.STRING) private OrderStatus status; private Date createTime; // 其他字段... } @Entity public class SelfPickupPoint { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private String address; private String contactPhone; @Enumerated(EnumType.STRING) private PickupPointStatus status; // 其他字段... } public enum OrderStatus { PENDING_PAYMENT, PAID, PICKED_UP, CANCELLED } public enum PickupPointStatus { ACTIVE, INACTIVE }

5. 前端（Uniapp）选择自提点组件

vue <template> <view class="pickup-point-selector"> <view class="title">选择自提点</view> <view v-for="point in pickupPoints" :key="point.id" class="point-item" :class="{ selected: selectedPointId === point.id }" @click="selectPoint(point.id)" > <view class="point-name">{{ point.name }}</view> <view class="point-address">{{ point.address }}</view> <view class="point-phone">{{ point.contactPhone }}</view> </view> </view> </template> <script> export default { data() { return { pickupPoints: [], // 从后端获取的自提点列表 selectedPointId: null }; }, methods: { selectPoint(pointId) { this.selectedPointId = pointId; // 触发父组件事件，将选中的自提点ID传递回去 this.$emit('point-selected', pointId); } }, created() { // 模拟从后端获取自提点列表 this.pickupPoints = [ { id: 1, name: "社区A自提点", address: "XX路XX号", contactPhone: "13800138000" }, { id: 2, name: "社区B自提点", address: "YY路YY号", contactPhone: "13900139000" } ]; } }; </script> <style> .pickup-point-selector { padding: 20rpx; } .point-item { border: 1px solid #eee; padding: 20rpx; margin-bottom: 20rpx; border-radius: 10rpx; } .point-item.selected { border-color: #07C160; background-color: #f0fff0; } </style>
