JAVA商城小程序APP公众号源码-单商户PC源码多商户源码社交电商源码的代码片段-深圳市維司達科技有限公司

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 ResponseEntity<MerchantResponse> 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 ResponseEntity<Void> 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 List<Store> 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 class="distribution"> <view class="share-card" @click="shareToWechat"> <image src="/static/share-icon.png"></image> <text>分享赚¥{{commissionAmount}}</text> </view> <!-- 分销关系链展示 --> <view class="relation-chain"> <text>分销路径：</text> <view v-for="(user,idx) in distributionChain" :key="idx" class="user-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') || []; } } </script>

3. 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 Map<String, 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 List<ProfitSharingRecipient> 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 Map<String, 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 } }); };
