以下为JAVA商城多端小程序/APP/公众号多商户社交电商核心功能代码片段涵盖商户管理、社交裂变、分账支付等模块1. 多商户入驻模块Spring Boot后端java // 商户入驻控制器 RestController RequestMapping(/api/merchant) public class MerchantController { PostMapping(/register) public ResponseEntityMerchantResponse register(RequestBody MerchantRegisterRequest request) { Merchant merchant new Merchant(); merchant.setName(request.getName()); merchant.setPhone(request.getPhone()); merchant.setStatus(MerchantStatus.PENDING); merchant.setCreateTime(new Date()); // 保存商户信息 Merchant saved merchantService.save(merchant); // 触发审核流程 rabbitTemplate.convertAndSend(audit_queue, new MerchantAuditEvent(saved.getId())); return ResponseEntity.ok(new MerchantResponse(saved)); } PutMapping(/{id}/approve) public ResponseEntityVoid approve(PathVariable Long id) { merchantService.approve(id); // 分配初始店铺ID storeService.createInitialStore(id); return ResponseEntity.ok().build(); } } // 商户实体类 Entity public class Merchant { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id; private String name; private String phone; private String businessLicense; // 营业执照号 Enumerated(EnumType.STRING) private MerchantStatus status; OneToMany(mappedBy merchant) private ListStore stores; }2. 社交电商分销模块Uniapp前端vue !-- 商品详情页分销组件 pages/product/detail.vue -- template view classdistribution view classshare-card clickshareToWechat image src/static/share-icon.png/image text分享赚¥{{commissionAmount}}/text /view !-- 分销关系链展示 -- view classrelation-chain text分销路径/text view v-for(user,idx) in distributionChain :keyidx classuser-node {{user.nickname}} ({{user.level}}级) /view /view /view /template script export default { data() { return { commissionAmount: 5.8, // 分销佣金 distributionChain: [] // 分销关系链 } }, methods: { shareToWechat() { // 生成带参数的分享链接 const shareUrl https://mall.com/product/${this.product.id}?distributor${this.userId}; // 调用微信分享API uni.share({ provider: weixin, type: 0, title: 发现好货, summary: this.product.name, imageUrl: this.product.cover, href: shareUrl, success: () { uni.showToast({ title: 分享成功 }); } }); } }, onLoad() { // 获取分销关系链 this.distributionChain uni.getStorageSync(distributionChain) || []; } } /script3. 拼团功能模块Spring Boot服务层java Service public class GroupBuyService { // 创建拼团 public GroupBuy createGroup(Long productId, Long userId, int groupSize) { GroupBuy group new GroupBuy(); group.setProductId(productId); group.setInitiatorId(userId); group.setGroupSize(groupSize); group.setExpireTime(new Date(System.currentTimeMillis() 2 * 60 * 60 * 1000)); // 2小时过期 group.setStatus(GroupBuyStatus.ONGOING); // 保存拼团主信息 GroupBuy saved groupBuyRepository.save(group); // 创建团长参团记录 GroupMember initiator new GroupMember(); initiator.setGroupId(saved.getId()); initiator.setUserId(userId); initiator.setRole(GroupRole.INITIATOR); groupMemberRepository.save(initiator); return saved; } // 用户加入拼团 public boolean joinGroup(Long groupId, Long userId) { GroupBuy group groupBuyRepository.findById(groupId) .orElseThrow(() - new GroupNotFoundException(groupId)); if(group.getStatus() ! GroupBuyStatus.ONGOING) { throw new GroupExpiredException(拼团已结束); } // 检查是否满员 long memberCount groupMemberRepository.countByGroupId(groupId); if(memberCount group.getGroupSize()) { group.setStatus(GroupBuyStatus.SUCCESS); groupBuyRepository.save(group); // 触发成团奖励发放 rewardService.issueGroupReward(group); } // 保存参团记录 GroupMember member new GroupMember(); member.setGroupId(groupId); member.setUserId(userId); member.setRole(GroupRole.MEMBER); groupMemberRepository.save(member); return true; } }4. 支付分账模块微信支付回调处理java RestController RequestMapping(/api/pay) public class PaymentController { PostMapping(/notify) public String handlePaymentNotify(RequestBody MapString, String notifyData) { // 解析微信支付回调 String orderId notifyData.get(out_trade_no); String totalAmount notifyData.get(total_fee); // 更新订单状态 Order order orderRepository.findByOrderId(orderId); order.setStatus(OrderStatus.PAID); orderRepository.save(order); // 执行分账 ListProfitSharingRecipient recipients new ArrayList(); // 平台抽成10% recipients.add(new ProfitSharingRecipient(PLATFORM, 10)); // 商户分账90% Merchant merchant merchantRepository.findByStoreId(order.getStoreId()); recipients.add(new ProfitSharingRecipient(merchant.getAccountId(), 90)); // 调用微信分账接口 MapString, String profitSharingResult wechatPayService.profitSharing( orderId, totalAmount, recipients ); return profitSharingResult.get(return_code); } }5. 社交关系链存储Uniapp前端javascript // 用户关系处理工具类 export const handleUserRelation (inviterId) { if(!inviterId) return; // 存储分销关系链 let relationChain uni.getStorageSync(distributionChain) || []; // 添加当前用户到关系链 const currentUser { id: uni.getStorageSync(userId), nickname: uni.getStorageSync(nickname), level: relationChain.length 1 }; // 添加到关系链 relationChain.push(currentUser); // 保存更新后的关系链 uni.setStorageSync(distributionChain, relationChain); // 上传关系链到后端 uni.request({ url: http://java-backend/api/relation/upload, method: POST, data: { inviterId: inviterId, chain: relationChain } }); };技术亮点说明多商户架构商户入驻审核流程、独立店铺管理、商品库存隔离社交裂变三级分销体系、拼团成团算法、分享链路追踪支付分账微信支付分账接口集成、平台与商户资金自动结算多端适配Uniapp实现小程序/APP/H5三端统一开发数据隔离不同商户数据通过store_id/merchant_id隔离存储关系链管理分销路径追踪、用户等级计算、佣金自动结算该代码片段展示了多商户社交电商的核心功能实现实际项目需补充商户后台管理、分销等级配置、拼团状态监控等模块并完善支付安全验证与异常处理机制。
