}5. 分佣规则设计5.1 常见分佣模式5.1.1 固定比例模式代码语言：javascript复制{
"rule_type": "FIXED_RATE",
"level_config": {
"level_1": 0.10,
"level_2": 0.05,
"level_3": 0.03
}
}5.1.2 阶梯比例模式代码语言：javascript复制{
"rule_type": "LADDER_RATE",
"level_config": [
{
"minAmount": 0,
"maxAmount": 100,
"rates": {
"level_1": 0.08,
"level_2": 0.04
}
},
{
"minAmount": 100,
"maxAmount": 500,
"rates": {
"level_1": 0.12,
"level_2": 0.06,
"level_3": 0.03
}
}
]
}5.1.3 团队业绩模式代码语言：javascript复制// 基于团队总业绩的分佣
public class TeamPerformanceRule {
private Map
private Map
public List
Order order,
User distributor,
TeamPerformance performance) {
// 计算个人业绩分佣
BigDecimal personalRate = getPersonalRate(performance.getPersonalSales());
BigDecimal personalCommission = order.getCommissionBase().multiply(personalRate);
// 计算团队管理分佣
BigDecimal teamRate = getTeamRate(performance.getTeamSales());
BigDecimal teamCommission = order.getCommissionBase().multiply(teamRate);
// 返回组合分佣
List
// ... 构建分佣详情
return details;
}
}5.2 防作弊机制代码语言：javascript复制@Service
public class AntiCheatService {
/**
* 分佣风控检查
*/
public CommissionRiskCheckResult riskCheck(Order order, List
CommissionRiskCheckResult result = new CommissionRiskCheckResult();
// 1. 自买自卖检测
if (isSelfTrading(order, details)) {
result.setHighRisk(true);
result.addRiskItem("自买自卖风险");
}
// 2. 异常关系链检测
if (hasAbnormalRelationChain(order.getUserId())) {
result.setHighRisk(true);
result.addRiskItem("异常关系链");
}
// 3. 高频交易检测
if (isHighFrequencyTrading(order.getUserId())) {
result.setMediumRisk(true);
result.addRiskItem("高频交易");
}
return result;
}
/**
* 自买自卖检测
*/
private boolean isSelfTrading(Order order, List
for (CommissionDetail detail : details) {
if (detail.getUserId().equals(order.getUserId())) {
return true;
}
}
return false;
}
}6. 性能优化方案6.1 数据库优化代码语言：javascript复制-- 添加合适的索引
CREATE INDEX idx_commission_user_status ON commission_records(user_id, status);
CREATE INDEX idx_relations_user_ancestor ON distribution_relations(user_id, ancestor_id);
CREATE INDEX idx_orders_user_created ON orders(user_id, created_at);
-- 分区表（按时间分区）
ALTER TABLE commission_records PARTITION BY RANGE (YEAR(created_at)) (
PARTITION p2023 VALUES LESS THAN (2024),
PARTITION p2024 VALUES LESS THAN (2025)
);6.2 缓存策略代码语言：javascript复制@Service
public class DistributionCacheService {
@Autowired
private RedisTemplate redisTemplate;
private static final String RELATION_CACHE_KEY = "dist:relation:%s";
private static final long RELATION_CACHE_TTL = 3600; // 1小时
/**
* 缓存用户关系链
*/
public void cacheUserRelations(Long userId, List
String key = String.format(RELATION_CACHE_KEY, userId);
redisTemplate.opsForValue().set(key, relations, RELATION_CACHE_TTL, TimeUnit.SECONDS);
}
/**
* 从缓存获取关系链
*/
public List
String key = String.format(RELATION_CACHE_KEY, userId);
return (List
}
}7. 总结本文详细介绍了分销系统的整体架构设计、数据库模型、核心代码实现以及分佣规则设计。关键要点包括：
架构清晰：采用分层架构，模块化设计关系管理：使用闭包表模式存储多级分销关系规则灵活：支持多种分佣模式，可配置化风控完善：内置防作弊机制，保障系统安全性能优化：通过缓存、索引等手段提升系统性能实际项目中还需要考虑分布式事务、数据一致性、系统监控等更多细节，但以上设计已经提供了一个坚实的分销系统基础框架。
