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

- Domain layer: ReportDefinition/ReportSnapshot aggregates, value objects (DateRange, ReportPeriod, etc.)
- Application layer: CQRS commands/queries, ReportingApplicationService
- Infrastructure layer: Prisma repositories, Redis cache, export services (Excel/CSV/PDF)
- API layer: REST controllers, DTOs with validation
- Testing: Unit tests, integration tests, E2E tests, Docker test environment
- Documentation: Architecture, API, Development, Testing, Deployment, Data Model docs
- Supports scheduled report generation, multi-format export, and data caching

## 4. 核心设计原则
### 4.1 依赖倒置原则 (DIP)
```typescript
// 领域层定义接口 (端口)
export interface IReportSnapshotRepository {
save(snapshot: ReportSnapshot): Promise<ReportSnapshot>;
findById(id: bigint): Promise<ReportSnapshot | null>;
findByCodeAndPeriodKey(code: string, periodKey: string): Promise<ReportSnapshot | null>;
}
// 基础设施层实现接口 (适配器)
@Injectable()
export class ReportSnapshotRepository implements IReportSnapshotRepository {
constructor(private readonly prisma: PrismaService) {}
async save(snapshot: ReportSnapshot): Promise<ReportSnapshot> {
// Prisma实现细节
}
}
```
### 4.2 聚合根设计
```typescript
// ReportSnapshot 聚合根
export class ReportSnapshot extends AggregateRoot {
private readonly _id: bigint;
private _reportType: ReportType;
private _reportCode: string;
private _reportPeriod: ReportPeriod;
private _snapshotData: SnapshotData;
private _events: DomainEvent[] = [];
// 工厂方法 - 创建新快照
public static create(props: CreateSnapshotProps): ReportSnapshot {
const snapshot = new ReportSnapshot(props);
snapshot.addDomainEvent(new SnapshotCreatedEvent(snapshot));
return snapshot;
}
// 从持久化重建 - 不触发事件
public static reconstitute(props: ReconstitutionProps): ReportSnapshot {
return new ReportSnapshot(props);
}
// 业务行为
public updateData(newData: SnapshotData): void {
this.validateDataUpdate(newData);
this._snapshotData = newData;
this._updatedAt = new Date();
}
}
```
### 4.3 值对象不可变性
```typescript
// DateRange 值对象
export class DateRange {
private readonly _startDate: Date;
private readonly _endDate: Date;
private constructor(startDate: Date, endDate: Date) {
this._startDate = startDate;
this._endDate = endDate;
Object.freeze(this);
}
public static create(startDate: Date, endDate: Date): DateRange {
if (startDate > endDate) {
throw new DomainException('Start date must be before end date');
}
return new DateRange(startDate, endDate);
}
public equals(other: DateRange): boolean {
return this._startDate.getTime() === other._startDate.getTime() &&
this._endDate.getTime() === other._endDate.getTime();
}
}
```
## 5. 数据流

ON system_account_monthly_stats(account_id, stat_month DESC);
-- 高频查询: 按日期和区域查询认种统计
CREATE INDEX idx_pds_date_region
ON planting_daily_stats(stat_date, province_code, city_code);
```
## 7. 数据保留策略
### 7.1 保留周期
| 表 | 保留周期 | 清理策略 |
|-----|---------|---------|
| report_snapshots | 90天 | 按 expires_at 清理 |
| report_files | 30天 | 按 expires_at 清理 |
| analytics_metrics | 365天 | 按 calculated_at 归档 |
| planting_daily_stats | 永久 | 按年归档 |
| system_account_income_records | 永久 | 按年归档 |
| report_events | 180天 | 按 occurred_at 清理 |
### 7.2 清理脚本
```sql
-- 清理过期快照
DELETE FROM report_snapshots
WHERE expires_at IS NOT NULL AND expires_at < NOW();
-- 清理过期文件
DELETE FROM report_files
WHERE expires_at IS NOT NULL AND expires_at < NOW();
-- 清理旧事件
DELETE FROM report_events
WHERE occurred_at < NOW() - INTERVAL '180 days';
```
## 8. Prisma Schema 映射
### 8.1 模型与表映射
| Prisma Model | 数据库表 | 主键映射 |
|--------------|---------|---------|
| ReportDefinition | report_definitions | definition_id |
| ReportSnapshot | report_snapshots | snapshot_id |
| ReportFile | report_files | file_id |
| AnalyticsMetric | analytics_metrics | metric_id |
| PlantingDailyStat | planting_daily_stats | stat_id |
| CommunityStat | community_stats | stat_id |
| SystemAccountMonthlyStat | system_account_monthly_stats | stat_id |
| SystemAccountIncomeRecord | system_account_income_records | record_id |
| ReportEvent | report_events | event_id |
### 8.2 关系映射
```prisma
// ReportSnapshot 1:N ReportFile
model ReportFile {
snapshot ReportSnapshot @relation(fields: [snapshotId], references: [id], onDelete: Cascade)
snapshotId BigInt @map("snapshot_id")
}
```
### 8.3 类型映射
| Prisma 类型 | PostgreSQL 类型 | 说明 |
|------------|----------------|------|
| BigInt | BIGSERIAL | 大整数主键 |
| String @db.VarChar(n) | VARCHAR(n) | 变长字符串 |
| String @db.Text | TEXT | 长文本 |
| Json | JSONB | JSON 二进制 |
| Decimal @db.Decimal(20,8) | DECIMAL(20,8) | 高精度数值 |
| DateTime | TIMESTAMP | 时间戳 |
| DateTime @db.Date | DATE | 日期 |
| Boolean | BOOLEAN | 布尔值 |
| String[] | VARCHAR(n)[] | 字符串数组 |

**TypeScript 配置** (`tsconfig.json`):
```json
{
"compilerOptions": {
"strict": true,
"strictNullChecks": true,
"noImplicitAny": true,
"noUnusedLocals": true,
"noUnusedParameters": true
}
}
```
**ESLint 规则** (关键规则):
```javascript
{
rules: {
'@typescript-eslint/explicit-function-return-type': 'warn',
'@typescript-eslint/no-explicit-any': 'warn',
'@typescript-eslint/no-unused-vars': 'error',
'no-console': 'warn'
}
}
```
### 4.4 领域驱动设计规范
**聚合根规则**:
```typescript
// 1. 使用私有属性 + getter
export class ReportSnapshot {
private readonly _id: bigint;
private _snapshotData: SnapshotData;
get id(): bigint { return this._id; }
get snapshotData(): SnapshotData { return this._snapshotData; }
// 2. 使用工厂方法创建
public static create(props: CreateProps): ReportSnapshot {
const snapshot = new ReportSnapshot(props);
snapshot.addDomainEvent(new SnapshotCreatedEvent(snapshot));
return snapshot;
}
// 3. 使用 reconstitute 重建 (不触发事件)
public static reconstitute(props: ReconstitutionProps): ReportSnapshot {
return new ReportSnapshot(props);
}
// 4. 业务方法封装状态变更
public updateData(newData: SnapshotData): void {
this.validateDataUpdate(newData);
this._snapshotData = newData;
this._updatedAt = new Date();
}
// 5. 私有构造函数
private constructor(props: Props) { ... }
}
```
**值对象规则**:
```typescript
// 1. 不可变
export class DateRange {
private readonly _startDate: Date;
private readonly _endDate: Date;
private constructor(startDate: Date, endDate: Date) {
this._startDate = startDate;
this._endDate = endDate;
Object.freeze(this); // 冻结对象
}
// 2. 工厂方法 + 验证
public static create(startDate: Date, endDate: Date): DateRange {
if (startDate > endDate) {
throw new DomainException('Invalid date range');
}
return new DateRange(startDate, endDate);
}
// 3. 实现 equals 方法
public equals(other: DateRange): boolean {
return this._startDate.getTime() === other._startDate.getTime() &&
this._endDate.getTime() === other._endDate.getTime();
}
}
```
## 5. Git 工作流
### 5.1 分支策略
```
main # 生产分支
├── develop # 开发分支
│ ├── feature/xxx # 功能分支
│ ├── bugfix/xxx # 修复分支
│ └── refactor/xxx # 重构分支
└── release/x.x.x # 发布分支
```
### 5.2 提交规范
使用 Conventional Commits:
```bash
# 格式
<type>(<scope>): <subject>
# 示例
feat(report): add daily report generation
fix(export): resolve Excel formatting issue
refactor(domain): extract value object for date range
test(e2e): add report generation tests
docs(api): update API documentation
```
**Type 类型**:
- `feat`: 新功能
- `fix`: Bug 修复
- `refactor`: 代码重构
- `test`: 测试相关
- `docs`: 文档更新
- `chore`: 构建/配置变更
- `perf`: 性能优化
### 5.3 PR 规范
PR 标题遵循提交规范，PR 描述需包含:
```markdown
## Summary
简要说明本次变更内容
## Changes
- 变更点 1
- 变更点 2
## Test Plan
- [ ] 单元测试通过
- [ ] 集成测试通过
- [ ] 手动测试场景
```
## 6. 调试技巧
### 6.1 VS Code 调试配置
`.vscode/launch.json`:
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug NestJS",
"runtimeArgs": ["--nolazy", "-r", "ts-node/register"],
"args": ["${workspaceFolder}/src/main.ts"],
"sourceMaps": true,
"envFile": "${workspaceFolder}/.env.development"
},
{
"type": "node",
"request": "launch",
"name": "Debug Jest Tests",
"program": "${workspaceFolder}/node_modules/.bin/jest",
"args": ["--runInBand", "--watchAll=false"],
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen"
}
]
}
```
### 6.2 日志调试
```typescript
import { Logger } from '@nestjs/common';
@Injectable()
export class ReportingApplicationService {
private readonly logger = new Logger(ReportingApplicationService.name);
async generateReport(dto: GenerateReportDto) {
this.logger.debug(`Generating report: ${dto.reportCode}`);
this.logger.log(`Report generated successfully`);
this.logger.warn(`Performance warning: slow query`);
this.logger.error(`Failed to generate report`, error.stack);
}
}
```
### 6.3 Prisma 调试
启用查询日志:
```typescript
// prisma.service.ts
const prisma = new PrismaClient({
log: [
{ level: 'query', emit: 'event' },
{ level: 'error', emit: 'stdout' },
{ level: 'warn', emit: 'stdout' },
],
});
prisma.$on('query', (e) => {
console.log('Query: ' + e.query);
console.log('Params: ' + e.params);
console.log('Duration: ' + e.duration + 'ms');
});
```
## 7. 常见问题
### Q: Prisma Client 未生成
```bash
npx prisma generate
```
### Q: 数据库连接失败
1. 检查 PostgreSQL 是否运行: `docker ps`
2. 检查 DATABASE_URL 环境变量
3. 检查网络连接和端口
### Q: 测试失败 - 表不存在
```bash
# 推送 schema 到测试数据库
DATABASE_URL="postgresql://..." npx prisma db push
```
### Q: TypeScript 编译错误
```bash
# 清理并重新构建
rm -rf dist
npm run build
```
### Q: 端口被占用
```bash
# 查找占用端口的进程
lsof -i :3000
# 或在 Windows
netstat -ano | findstr :3000
```

```
## 7. 测试最佳实践
### 7.1 测试命名规范
```typescript
describe('ClassName', () => {
describe('methodName', () => {
it('should [expected behavior] when [condition]', () => {
// test implementation
});
});
});
```
### 7.2 AAA 模式
```typescript
it('should create valid date range', () => {
// Arrange - 准备测试数据
const startDate = new Date('2024-01-01');
const endDate = new Date('2024-01-31');
// Act - 执行被测试的操作
const dateRange = DateRange.create(startDate, endDate);
// Assert - 验证结果
expect(dateRange.startDate).toEqual(startDate);
expect(dateRange.endDate).toEqual(endDate);
});
```
### 7.3 测试隔离
```typescript
describe('Repository Integration Tests', () => {
beforeEach(async () => {
// 每个测试前清理数据
await prismaService.reportSnapshot.deleteMany();
await prismaService.reportDefinition.deleteMany();
});
afterAll(async () => {
// 测试结束后断开连接
await prismaService.$disconnect();
});
});
```
### 7.4 Mock 使用
```typescript
// 使用 Jest mock
const mockRepository = {
findByCode: jest.fn(),
save: jest.fn(),
findAll: jest.fn(),
};
beforeEach(() => {
jest.clearAllMocks();
});
it('should call repository with correct parameters', async () => {
mockRepository.findByCode.mockResolvedValue(mockDefinition);
await service.getReportDefinition('RPT_TEST');
expect(mockRepository.findByCode).toHaveBeenCalledWith('RPT_TEST');
});
```
## 8. CI/CD 集成
### 8.1 GitHub Actions

## 9. 故障排除
### 9.1 常见问题
**Q: 测试找不到模块**
```bash
# 重新生成 Prisma Client
npx prisma generate
```
**Q: 数据库连接失败**
```bash
# 检查容器状态
docker ps
# 检查数据库日志
docker logs reporting-postgres-test
```
**Q: E2E 测试响应格式错误**
```typescript
// 确保不要重复注册 TransformInterceptor
// AppModule 中已注册，测试中不需要再次注册
```
**Q: Docker 测试 Prisma 错误**
```dockerfile
# 确保 Dockerfile.test 包含 OpenSSL
RUN apk add --no-cache openssl openssl-dev
```
### 9.2 调试测试
```bash
# 运行单个测试文件
npm test -- --testPathPattern=date-range.spec.ts
# 详细输出
npm test -- --verbose
# 调试模式
node --inspect-brk node_modules/.bin/jest --runInBand
```
