feat(leaderboard-service): Implement complete leaderboard service with DDD architecture 

## Features
- Daily/Weekly/Monthly leaderboard management
- Ranking score calculation (effectiveScore = totalTeamPlanting - maxDirectTeamPlanting)
- Virtual ranking system for display purposes
- Real-time ranking updates via scheduled tasks
- Redis caching for hot data
- Kafka messaging for event-driven updates

## Architecture
- Domain-Driven Design (DDD) with Hexagonal Architecture
- NestJS 10.x + TypeScript 5.x
- PostgreSQL 15 + Prisma ORM
- Redis (ioredis) for caching
- Kafka (kafkajs) for messaging
- JWT + Passport for authentication
- Swagger for API documentation

## Domain Layer
- Aggregates: LeaderboardRanking, LeaderboardConfig
- Entities: VirtualAccount
- Value Objects: LeaderboardType, LeaderboardPeriod, RankingScore, RankPosition, UserSnapshot
- Domain Events: LeaderboardRefreshedEvent, ConfigUpdatedEvent, RankingChangedEvent
- Domain Services: LeaderboardCalculationService, VirtualRankingGeneratorService, RankingMergerService

## Infrastructure Layer
- Prisma repositories implementation
- Redis cache service
- Kafka event publisher/consumer
- External service clients (ReferralService, IdentityService)

## Testing
- Unit tests: 72 tests passed (88% coverage on core domain)
- Integration tests: 7 tests passed
- E2E tests: 11 tests passed
- Docker containerized tests: 79 tests passed

## Documentation
- docs/ARCHITECTURE.md - Architecture design
- docs/API.md - API specification
- docs/DEVELOPMENT.md - Development guide
- docs/TESTING.md - Testing guide
- docs/DEPLOYMENT.md - Deployment guide

## 3. 领域模型设计
### 3.1 聚合根
#### LeaderboardRanking（排名聚合）
```typescript
class LeaderboardRanking {
// 标识
id: bigint;
// 榜单信息
leaderboardType: LeaderboardType; // DAILY | WEEKLY | MONTHLY
period: LeaderboardPeriod;
// 用户信息
userId: bigint;
isVirtual: boolean;
// 排名信息
rankPosition: RankPosition; // 实际排名
displayPosition: RankPosition; // 显示排名
previousRank: RankPosition | null;
// 分值信息
score: RankingScore;
// 用户快照
userSnapshot: UserSnapshot;
}
```
#### LeaderboardConfig（配置聚合）
```typescript
class LeaderboardConfig {
// 标识
id: bigint;
configKey: string;
// 榜单开关
dailyEnabled: boolean;
weeklyEnabled: boolean;
monthlyEnabled: boolean;
// 虚拟排名设置
virtualRankingEnabled: boolean;
virtualAccountCount: number;
// 显示设置
displayLimit: number;
refreshIntervalMinutes: number;
}
```
### 3.2 值对象
#### RankingScore（排名分值）
```typescript
// 龙虎榜分值计算公式：
// effectiveScore = totalTeamPlanting - maxDirectTeamPlanting
class RankingScore {
totalTeamPlanting: number; // 团队总认种
maxDirectTeamPlanting: number; // 最大单个直推团队认种
effectiveScore: number; // 有效分值（龙虎榜分值）
static calculate(total: number, maxDirect: number): RankingScore {
const effective = Math.max(0, total - maxDirect);
return new RankingScore(total, maxDirect, effective);
}
}
```
#### LeaderboardPeriod（周期）
```typescript
class LeaderboardPeriod {
key: string; // 2024-01-15 | 2024-W03 | 2024-01
startAt: Date;
endAt: Date;
static currentDaily(): LeaderboardPeriod;
static currentWeekly(): LeaderboardPeriod;
static currentMonthly(): LeaderboardPeriod;
}
```
### 3.3 领域事件
| 事件 | 触发时机 | 数据 |
|------|----------|------|
| LeaderboardRefreshedEvent | 榜单刷新完成 | type, period, rankings |
| ConfigUpdatedEvent | 配置变更 | configKey, changes |
| RankingChangedEvent | 用户排名变化 | userId, oldRank, newRank |
## 4. 数据模型

│ is_active │ 是否激活 │
│ created_at │ 创建时间 │
│ updated_at │ 更新时间 │
└─────────────────────────────────────────────────────────────────┘
```
### 4.2 缓存设计
```
Redis Key 设计:
leaderboard:{type}:{period}:rankings # 排名列表 (ZSET)
leaderboard:{type}:{period}:user:{id} # 用户排名详情 (HASH)
leaderboard:config # 全局配置 (HASH)
leaderboard:virtual:accounts # 虚拟账户列表 (LIST)
TTL:
- 日榜: 10 分钟
- 周榜: 30 分钟
- 月榜: 1 小时
- 配置: 5 分钟
```

level: 'info',
timestamp: '2024-01-15T10:30:00Z',
service: 'leaderboard-service',
traceId: 'abc123',
message: 'Leaderboard refreshed',
context: {
type: 'DAILY',
period: '2024-01-15',
totalRankings: 100
}
}
```
### 8.2 健康检查

## 4. 代码结构指南
### 4.1 领域层开发
#### 创建值对象
```typescript
// src/domain/value-objects/example.vo.ts
export class ExampleValueObject {
private constructor(
public readonly value: string,
) {}
static create(value: string): ExampleValueObject {
// 验证逻辑
if (!value || value.length === 0) {
throw new Error('Value cannot be empty');
}
return new ExampleValueObject(value);
}
equals(other: ExampleValueObject): boolean {
return this.value === other.value;
}
}
```
#### 创建聚合根
```typescript
// src/domain/aggregates/example/example.aggregate.ts
import { DomainEvent } from '../../events/domain-event.base';
export class ExampleAggregate {
private _domainEvents: DomainEvent[] = [];
private constructor(
public readonly id: bigint,
private _name: string,
) {}
// 工厂方法
static create(props: CreateExampleProps): ExampleAggregate {
const aggregate = new ExampleAggregate(
props.id,
props.name,
);
aggregate.addDomainEvent(new ExampleCreatedEvent(aggregate));
return aggregate;
}
// 业务方法
updateName(newName: string, operator: string): void {
if (this._name === newName) return;
const oldName = this._name;
this._name = newName;
this.addDomainEvent(new NameUpdatedEvent(this.id, oldName, newName));
}
// 领域事件
get domainEvents(): DomainEvent[] {
return [...this._domainEvents];
}
private addDomainEvent(event: DomainEvent): void {
this._domainEvents.push(event);
}
clearDomainEvents(): void {
this._domainEvents = [];
}
}
```
#### 创建领域服务
```typescript
// src/domain/services/example.service.ts
import { Injectable } from '@nestjs/common';
@Injectable()
export class ExampleDomainService {
/**
* 复杂的业务逻辑，不属于单个聚合根
*/
calculateComplexBusinessLogic(
aggregate1: Aggregate1,
aggregate2: Aggregate2,
): Result {
// 跨聚合的业务逻辑
}
}
```
### 4.2 基础设施层开发
#### 实现仓储
```typescript
// src/infrastructure/repositories/example.repository.impl.ts
import { Injectable } from '@nestjs/common';
import { PrismaService } from '../database/prisma.service';
import { IExampleRepository } from '../../domain/repositories/example.repository.interface';
@Injectable()
export class ExampleRepositoryImpl implements IExampleRepository {
constructor(private readonly prisma: PrismaService) {}
async findById(id: bigint): Promise<ExampleAggregate | null> {
const data = await this.prisma.example.findUnique({
where: { id },
});
if (!data) return null;
return this.toDomain(data);
}
async save(aggregate: ExampleAggregate): Promise<void> {
const data = this.toPersistence(aggregate);
await this.prisma.example.upsert({
where: { id: aggregate.id },
create: data,
update: data,
});
}
// 映射方法
private toDomain(data: PrismaExample): ExampleAggregate {
// Prisma 模型 -> 领域模型
}
private toPersistence(aggregate: ExampleAggregate): PrismaExampleInput {
// 领域模型 -> Prisma 模型
}
}
```
### 4.3 应用层开发
#### 创建应用服务
```typescript
// src/application/services/example-application.service.ts
import { Injectable, Inject } from '@nestjs/common';
import { IExampleRepository } from '../../domain/repositories/example.repository.interface';
@Injectable()
export class ExampleApplicationService {
constructor(
@Inject('IExampleRepository')
private readonly exampleRepository: IExampleRepository,
private readonly eventPublisher: EventPublisherService,
) {}
async executeUseCase(command: ExampleCommand): Promise<ExampleResult> {
// 1. 加载聚合
const aggregate = await this.exampleRepository.findById(command.id);
// 2. 执行业务逻辑
aggregate.doSomething(command.data);
// 3. 持久化
await this.exampleRepository.save(aggregate);
// 4. 发布领域事件
await this.eventPublisher.publishAll(aggregate.domainEvents);
aggregate.clearDomainEvents();
// 5. 返回结果
return new ExampleResult(aggregate);
}
}
```
### 4.4 API 层开发
#### 创建控制器
```typescript
// src/api/controllers/example.controller.ts
import {
Controller,
Get,
Post,
Body,
Param,
UseGuards,
} from '@nestjs/common';
import { ApiTags, ApiOperation, ApiBearerAuth } from '@nestjs/swagger';
import { JwtAuthGuard } from '../guards/jwt-auth.guard';
@ApiTags('Example')
@Controller('example')
export class ExampleController {
constructor(
private readonly exampleService: ExampleApplicationService,
) {}
@Get(':id')
@ApiOperation({ summary: '获取示例' })
async getById(@Param('id') id: string) {
return this.exampleService.findById(BigInt(id));
}
@Post()
@UseGuards(JwtAuthGuard)
@ApiBearerAuth()
@ApiOperation({ summary: '创建示例' })
async create(@Body() dto: CreateExampleDto) {
return this.exampleService.create(dto);
}
}
```
#### 创建 DTO
```typescript
// src/api/dto/example.dto.ts
import { ApiProperty } from '@nestjs/swagger';
import { IsString, IsNotEmpty, IsOptional, Min, Max } from 'class-validator';
export class CreateExampleDto {
@ApiProperty({ description: '名称', example: '示例名称' })
@IsString()
@IsNotEmpty()
name: string;
@ApiProperty({ description: '描述', required: false })
@IsString()
@IsOptional()
description?: string;
@ApiProperty({ description: '数量', minimum: 1, maximum: 100 })
@Min(1)
@Max(100)
count: number;
}
```
## 5. 调试指南
### 5.1 VS Code 调试配置
创建 `.vscode/launch.json`：
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug NestJS",
"runtimeArgs": [
"--nolazy",
"-r",
"ts-node/register",
"-r",
"tsconfig-paths/register"
],
"args": ["${workspaceFolder}/src/main.ts"],
"sourceMaps": true,
"cwd": "${workspaceFolder}",
"protocol": "inspector"
},
{
"type": "node",
"request": "launch",
"name": "Debug Tests",
"program": "${workspaceFolder}/node_modules/.bin/jest",
"args": ["--runInBand", "--config", "jest.config.js"],
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
}
]
}
```
### 5.2 日志调试
```typescript
import { Logger } from '@nestjs/common';
@Injectable()
export class ExampleService {
private readonly logger = new Logger(ExampleService.name);
async doSomething() {
this.logger.debug('开始处理...');
this.logger.log('处理完成');
this.logger.warn('警告信息');
this.logger.error('错误信息', error.stack);
}
}
```
### 5.3 Prisma 查询日志
在 `prisma.service.ts` 中启用：
```typescript
const prisma = new PrismaClient({
log: ['query', 'info', 'warn', 'error'],
});
```
## 6. 常见问题
### 6.1 Prisma Client 生成失败
```bash
# 删除现有 client
rm -rf node_modules/.prisma
# 重新生成
npx prisma generate
```
### 6.2 数据库连接失败
检查：
1. PostgreSQL 服务是否运行
2. `DATABASE_URL` 配置是否正确
3. 数据库用户权限
### 6.3 Redis 连接失败
检查：
1. Redis 服务是否运行
2. `REDIS_HOST` 和 `REDIS_PORT` 配置
3. 防火墙设置
### 6.4 热重载不生效
```bash
# 清理缓存
rm -rf dist
# 重新启动
npm run start:dev
```
### 6.5 BigInt 序列化问题
在 `main.ts` 中添加：
```typescript
// BigInt 序列化支持
(BigInt.prototype as any).toJSON = function () {
return this.toString();
};
```
## 7. 性能优化建议
### 7.1 数据库查询
```typescript
// 使用 select 限制返回字段
await prisma.user.findMany({
select: {
id: true,
name: true,
},
});
// 使用分页
await prisma.ranking.findMany({
skip: (page - 1) * limit,
take: limit,
orderBy: { score: 'desc' },
});
// 使用事务
await prisma.$transaction([
prisma.ranking.deleteMany({ where: { periodKey } }),
prisma.ranking.createMany({ data: rankings }),
]);
```
### 7.2 缓存使用
```typescript
// 缓存查询结果
async getLeaderboard(type: string, period: string) {
const cacheKey = `leaderboard:${type}:${period}`;
// 尝试从缓存读取
const cached = await this.redis.get(cacheKey);
if (cached) {
return JSON.parse(cached);
}
// 从数据库查询
const data = await this.repository.findByPeriod(type, period);
// 写入缓存
await this.redis.setex(cacheKey, 600, JSON.stringify(data));
return data;
}
```
### 7.3 异步处理
```typescript
// 使用事件驱动
@OnEvent('ranking.updated')
async handleRankingUpdated(event: RankingUpdatedEvent) {
// 异步处理，不阻塞主流程
await this.notificationService.notifyUser(event.userId);
}
```
## 8. 安全注意事项
### 8.1 输入验证
```typescript
// 使用 class-validator
@IsString()
@IsNotEmpty()
@MaxLength(100)
name: string;
@IsInt()
@Min(1)
@Max(100)
limit: number;
```
### 8.2 SQL 注入防护
```typescript
// 使用参数化查询（Prisma 自动处理）
await prisma.user.findFirst({
where: { email: userInput }, // 安全
});
// 避免原始查询
// await prisma.$queryRaw`SELECT * FROM users WHERE email = ${userInput}`
```
### 8.3 敏感数据处理
```typescript
// 响应时过滤敏感字段
return {
id: user.id,
nickname: user.nickname,
// 不返回 password, email 等敏感信息
};
```

REDIS_PORT: 6379
JWT_SECRET: test-jwt-secret
volumes:
- ./coverage:/app/coverage
command: >
sh -c "npx prisma migrate deploy && npm test -- --coverage"
```
### 5.2 使用 Makefile 运行测试
```makefile
# Makefile
.PHONY: test test-unit test-integration test-e2e test-docker-unit test-docker-all
# 本地测试
test: test-unit
test-unit:
npm test
test-integration:
npm run test:integration
test-e2e:
npm run test:e2e
test-cov:
npm run test:cov
# Docker 测试
test-docker-unit:
docker compose -f docker-compose.test.yml up --build --abort-on-container-exit test-runner
docker compose -f docker-compose.test.yml down -v
test-docker-integration:
docker compose -f docker-compose.test.yml up --build --abort-on-container-exit integration-test-runner
docker compose -f docker-compose.test.yml down -v
test-docker-e2e:
docker compose -f docker-compose.test.yml up --build --abort-on-container-exit e2e-test-runner
docker compose -f docker-compose.test.yml down -v
test-docker-all: test-docker-unit test-docker-integration test-docker-e2e
```
### 5.3 运行 Docker 测试
```bash
# 单元测试
make test-docker-unit
# 集成测试
make test-docker-integration
# E2E 测试
make test-docker-e2e
# 所有测试
make test-docker-all
```
## 6. 手动测试指南
### 6.1 使用 cURL 测试
```bash
# 健康检查
curl http://localhost:3000/health
# 获取日榜
curl http://localhost:3000/leaderboard/daily
# 获取周榜
curl http://localhost:3000/leaderboard/weekly?limit=10
# 带认证的请求
curl -H "Authorization: Bearer <token>" \
http://localhost:3000/leaderboard/my-rank
# 管理员操作
curl -X POST \
-H "Authorization: Bearer <admin-token>" \
-H "Content-Type: application/json" \
-d '{"type": "daily", "enabled": false}' \
http://localhost:3000/leaderboard/config/switch
```
### 6.2 使用 VS Code REST Client
创建 `test.http` 文件：
```http
### 健康检查
GET http://localhost:3000/health
### 获取日榜
GET http://localhost:3000/leaderboard/daily?limit=10
### 获取周榜
GET http://localhost:3000/leaderboard/weekly
### 获取月榜
GET http://localhost:3000/leaderboard/monthly
### 获取我的排名 (需要 token)
GET http://localhost:3000/leaderboard/my-rank
Authorization: Bearer {{token}}
### 获取配置 (管理员)
GET http://localhost:3000/leaderboard/config
Authorization: Bearer {{adminToken}}
### 更新榜单开关 (管理员)
POST http://localhost:3000/leaderboard/config/switch
Authorization: Bearer {{adminToken}}
Content-Type: application/json
{
"type": "daily",
"enabled": false
}
### 手动刷新排行榜 (管理员)
POST http://localhost:3000/leaderboard/config/refresh
Authorization: Bearer {{adminToken}}
Content-Type: application/json
{
"type": "DAILY"
}
```
### 6.3 使用 Postman
1. 导入 OpenAPI 规范：`http://localhost:3000/api-docs-json`
2. 设置环境变量：
- `baseUrl`: `http://localhost:3000`
- `token`: 用户 JWT token
- `adminToken`: 管理员 JWT token
## 7. 测试最佳实践
### 7.1 测试命名规范
```typescript
describe('被测试的类/函数', () => {
describe('方法名', () => {
it('应该做什么（正常情况）', () => {});
it('当什么条件时应该如何（边界情况）', () => {});
it('什么情况应该抛出错误（异常情况）', () => {});
});
});
```
### 7.2 AAA 模式
```typescript
it('应该正确计算分值', () => {
// Arrange - 准备
const totalTeam = 200;
const maxDirect = 50;
// Act - 执行
const score = RankingScore.calculate(totalTeam, maxDirect);
// Assert - 断言
expect(score.effectiveScore).toBe(150);
});
```
### 7.3 Mock 使用
```typescript
// 创建 Mock
const mockRepository = {
findById: jest.fn(),
save: jest.fn(),
};
// 设置返回值
mockRepository.findById.mockResolvedValue(mockAggregate);
// 验证调用
expect(mockRepository.save).toHaveBeenCalledWith(expect.objectContaining({
id: expectedId,
}));
```
### 7.4 测试隔离
```typescript
beforeEach(async () => {
// 每个测试前清理数据
await global.testUtils.cleanDatabase();
});
afterEach(() => {
// 清理 mock
jest.clearAllMocks();
});
```
## 8. CI/CD 集成
