**Clean Architecture 적용**
1. **Domain Layer (Core)**
- 순수 비즈니스 로직
- 외부 의존성 없음
2. **Application Layer (Use Cases)**
- 비즈니스 유스케이스 구현
- Domain과 Infrastructure 연결
3. **Infrastructure Layer**
- 외부 시스템 연동
- 데이터베이스, API, 메시징
4. **Presentation Layer**
- REST API 컨트롤러
- 요청/응답 처리
**의존성 규칙:**
Presentation → Application → Domain
Infrastructure → Application
(Domain은 외부 의존성 없음)

**Controller 메소드 - API 매핑**
distribute: POST /distribution/distribute
- 다중 채널 배포 요청
getDistributionStatus: GET /distribution/{eventId}/status
- 배포 상태 조회
end note
note top of DistributionService
**핵심 비즈니스 로직**
• 다중 채널 병렬 배포
• ExecutorService 기반 비동기 처리
• 배포 상태 관리 (저장/조회)
• Kafka 이벤트 발행
distribute(request)
→ 병렬 배포 실행
→ 결과 집계
→ 상태 저장
→ 이벤트 발행
end note
note top of AbstractChannelAdapter
**Resilience4j 패턴 적용**
• Circuit Breaker
• Retry (지수 백오프)
• Bulkhead (리소스 격리)
• Fallback 처리
각 채널별 독립적 장애 격리
end note
note top of DistributionStatusRepository
**배포 상태 영구 저장**
• PostgreSQL 저장
• JPA Repository 패턴
• Entity ↔ DTO 매핑
save(eventId, status)
findByEventId(eventId)
end note
note right of ChannelType
**배포 채널 종류**
TV 채널:
• URIDONGNETV (우리동네TV)
• GINITV (지니TV)

• RINGOBIZ (링고비즈)
SNS 채널:
• INSTAGRAM
• NAVER (Blog)
• KAKAO (Channel)
end note

**배포 상태 엔티티**
전체 배포 상태 관리:
• PENDING: 대기중
• IN_PROGRESS: 진행중
• COMPLETED: 완료
• PARTIAL_FAILURE: 부분성공
• FAILED: 실패
1:N 관계로 채널별 상태 관리
end note

**Kafka 이벤트 발행**
Topic: distribution-completed
배포 완료 시 이벤트 발행

# Event Service 클래스 설계서
## 1. 개요
### 1.1 목적
Event Service의 Clean Architecture 기반 클래스 설계를 정의합니다.
### 1.2 설계 원칙
- **아키텍처 패턴**: Clean Architecture
- **패키지 그룹**: com.kt.event
- **의존성 방향**: Presentation → Application → Domain ← Infrastructure
### 1.3 핵심 특징
- 복잡한 이벤트 생명주기 관리 (DRAFT → PUBLISHED → ENDED)
- 상태 머신 패턴 적용
- AI 서비스 비동기 연동 (Kafka)
- Content Service 동기 연동 (Feign)
- Redis 캐시 활용
---
## 2. 계층별 구조
### 2.1 Domain Layer (핵심 비즈니스 로직)
#### 2.1.1 Entity
**Event (이벤트 집합 루트)**
```java
- 책임: 이벤트 전체 생명주기 관리
- 상태: DRAFT, PUBLISHED, ENDED
- 비즈니스 규칙:
* DRAFT 상태에서만 수정 가능
* 배포 필수 데이터 검증 (이벤트명, 기간, 이미지, 채널)
* 상태 전이 제약 (DRAFT PUBLISHED ENDED)
- 관계:
* 1:N GeneratedImage (생성된 이미지)
* 1:N AiRecommendation (AI 추천안)
```
**AiRecommendation (AI 추천 엔티티)**
```java
- 책임: AI가 생성한 이벤트 기획안 관리
- 속성: 이벤트명, 설명, 프로모션 유형, 타겟 고객
- 선택 상태: isSelected (단일 선택)
```
**GeneratedImage (생성 이미지 엔티티)**
```java
- 책임: 이벤트별 생성된 이미지 관리
- 속성: 이미지 URL, 스타일, 플랫폼
- 선택 상태: isSelected (단일 선택)
```
**Job (비동기 작업 엔티티)**
```java
- 책임: AI 추천, 이미지 생성 비동기 작업 상태 관리
- 상태: PENDING, PROCESSING, COMPLETED, FAILED
- 진행률: 0~100 (progress)
- 결과: Redis (resultKey) 또는 에러 메시지
```
#### 2.1.2 Enums
- **EventStatus**: DRAFT, PUBLISHED, ENDED
- **JobStatus**: PENDING, PROCESSING, COMPLETED, FAILED
- **JobType**: AI_RECOMMENDATION, IMAGE_GENERATION
#### 2.1.3 Repository Interfaces
- **EventRepository**: 이벤트 조회, 필터링, 페이징
- **AiRecommendationRepository**: AI 추천 관리
- **GeneratedImageRepository**: 이미지 관리
- **JobRepository**: 작업 상태 관리
---
### 2.2 Application Layer (유스케이스)
#### 2.2.1 Services
**EventService (핵심 오케스트레이터)**
```java
책임:
- 이벤트 전체 생명주기 조율
- AI 서비스 연동 (Kafka 비동기)
- Content 서비스 연동 (Feign 동기)
- 트랜잭션 경계 관리
주요 유스케이스:
1. createEvent(): 이벤트 생성 (Step 1: 목적 선택)
2. requestAiRecommendations(): AI 추천 요청 (Step 2)
3. selectRecommendation(): AI 추천 선택
4. requestImageGeneration(): 이미지 생성 요청 (Step 3)
5. selectImage(): 이미지 선택
6. selectChannels(): 배포 채널 선택 (Step 4)
7. publishEvent(): 이벤트 배포 (Step 5)
8. endEvent(): 이벤트 종료
```
**JobService (작업 관리)**
```java
책임:
- 비동기 작업 상태 조회
- 작업 진행률 업데이트
- 작업 완료/실패 처리
주요 유스케이스:
1. createJob(): 작업 생성
2. getJobStatus(): 작업 상태 조회
3. updateJobProgress(): 진행률 업데이트
4. completeJob(): 작업 완료 처리
5. failJob(): 작업 실패 처리
```
#### 2.2.2 DTOs
**Request DTOs**
- SelectObjectiveRequest: 목적 선택
- AiRecommendationRequest: AI 추천 요청 (매장 정보 포함)
- SelectRecommendationRequest: AI 추천 선택 + 커스터마이징
- ImageGenerationRequest: 이미지 생성 요청 (스타일, 플랫폼)
- SelectImageRequest: 이미지 선택
- ImageEditRequest: 이미지 편집
- SelectChannelsRequest: 배포 채널 선택
- UpdateEventRequest: 이벤트 수정
**Response DTOs**
- EventCreatedResponse: 이벤트 생성 응답
- EventDetailResponse: 이벤트 상세 (이미지, 추천 포함)
- JobAcceptedResponse: 작업 접수 응답
- JobStatusResponse: 작업 상태 응답
- ImageGenerationResponse: 이미지 생성 응답
**Kafka Message DTOs**
- AIEventGenerationJobMessage: AI 작업 메시지
- ImageGenerationJobMessage: 이미지 생성 작업 메시지
- EventCreatedMessage: 이벤트 생성 이벤트
---
### 2.3 Infrastructure Layer (기술 구현)
#### 2.3.1 Kafka (비동기 메시징)
**AIJobKafkaProducer**
```java
책임: AI 추천 생성 작업 발행
토픽: ai-event-generation-job
메시지: AIEventGenerationJobMessage
```
**AIJobKafkaConsumer**
```java
책임: AI 작업 결과 수신 처리
처리: COMPLETED, FAILED, PROCESSING 상태별 분기
수동 커밋: Acknowledgment 사용
```
**ImageJobKafkaConsumer**
```java
책임: 이미지 생성 작업 결과 수신
처리: 생성된 이미지 DB 저장
```
**EventKafkaProducer**
```java
책임: 이벤트 생성 이벤트 발행
토픽: event-created
용도: Distribution Service 연동
```
#### 2.3.2 Client (외부 서비스 연동)
**ContentServiceClient (Feign)**
```java
대상: Content Service (포트 8082)
API: POST /api/v1/content/images/generate
요청: ContentImageGenerationRequest
응답: ContentJobResponse (Job ID 반환)
```
#### 2.3.3 Config
**RedisConfig**
```java
책임: Redis 연결 설정
용도:
- AI 추천 결과 임시 저장
- 이미지 생성 결과 임시 저장
- Job 결과 캐싱
```
---
### 2.4 Presentation Layer (API)
#### 2.4.1 Controllers
**EventController**
```java
Base Path: /api/v1/events
주요 엔드포인트:
1. POST /objectives - 이벤트 목적 선택 (생성)
2. GET /events - 이벤트 목록 조회 (페이징, 필터링)
3. GET /events/{id} - 이벤트 상세 조회
4. DELETE /events/{id} - 이벤트 삭제
5. POST /events/{id}/publish - 이벤트 배포
6. POST /events/{id}/end - 이벤트 종료
7. POST /events/{id}/ai-recommendations - AI 추천 요청
8. PUT /events/{id}/recommendations - AI 추천 선택
9. POST /events/{id}/images - 이미지 생성 요청
10. PUT /events/{id}/images/{imageId}/select - 이미지 선택
11. PUT /events/{id}/images/{imageId}/edit - 이미지 편집
12. PUT /events/{id}/channels - 배포 채널 선택
13. PUT /events/{id} - 이벤트 수정
```
**JobController**
```java
Base Path: /api/v1/jobs
엔드포인트:
1. GET /jobs/{id} - 작업 상태 조회
```
---
## 3. 핵심 플로우
### 3.1 이벤트 생성 플로우
```
1. 목적 선택 (POST /objectives)
→ Event 생성 (DRAFT 상태)
2. AI 추천 요청 (POST /events/{id}/ai-recommendations)
→ Job 생성 (AI_RECOMMENDATION)
→ Kafka 메시지 발행 (ai-event-generation-job)
→ AI Service 처리
→ Kafka 메시지 수신 (결과)
→ Redis 캐시 저장
→ Job 완료 처리
3. AI 추천 선택 (PUT /events/{id}/recommendations)
→ Redis에서 추천 목록 조회
→ 선택 + 커스터마이징 적용
→ Event 업데이트 (eventName, description, period)
4. 이미지 생성 요청 (POST /events/{id}/images)
→ Content Service 호출 (Feign)
→ Job ID 반환
→ 폴링으로 상태 확인
5. 이미지 선택 (PUT /events/{id}/images/{imageId}/select)
→ Event.selectedImageId 업데이트
→ GeneratedImage.isSelected = true
6. 배포 채널 선택 (PUT /events/{id}/channels)
→ Event.channels 업데이트
7. 이벤트 배포 (POST /events/{id}/publish)
→ 필수 데이터 검증
→ 상태 변경 (DRAFT → PUBLISHED)
→ Kafka 메시지 발행 (event-created)
```
### 3.2 상태 머신 다이어그램
```
DRAFT → publish() → PUBLISHED → end() → ENDED
↑ |
| ↓
└─────── (수정 불가) ─────┘
```
**상태별 제약:**
- DRAFT: 모든 수정 가능, 삭제 가능
- PUBLISHED: 수정 불가, 삭제 불가, 종료만 가능
- ENDED: 모든 변경 불가 (읽기 전용)
---
## 4. 비동기 작업 처리
### 4.1 Job 생명주기
```
PENDING → start() → PROCESSING → complete() → COMPLETED
fail() → FAILED
```
### 4.2 작업 유형별 처리
**AI_RECOMMENDATION (AI 추천 생성)**
- 발행: AIJobKafkaProducer
- 수신: AIJobKafkaConsumer
- 결과: Redis 캐시 (추천 목록)
- 시간: 10~30초
**IMAGE_GENERATION (이미지 생성)**
- 발행: EventService → ContentServiceClient
- 수신: ImageJobKafkaConsumer (Content Service에서 발행)
- 결과: GeneratedImage 엔티티 (DB 저장)
- 시간: 30~60초

## 6. 의존성 방향
### 6.1 Clean Architecture 계층
```
Presentation Layer (EventController)
↓ depends on
Application Layer (EventService)
↓ depends on
Domain Layer (Event, EventRepository)
↑ implements
Infrastructure Layer (EventRepositoryImpl, Kafka, Feign)
```
### 6.2 핵심 원칙
1. **Domain Layer는 외부 의존성 없음** (순수 비즈니스 로직)
2. **Application Layer는 Domain을 조율** (유스케이스)
3. **Infrastructure Layer는 Domain 인터페이스 구현** (기술 세부사항)
4. **Presentation Layer는 Application 호출** (API 엔드포인트)
---
## 7. 주요 설계 패턴
### 7.1 Domain 패턴
- **Aggregate Root**: Event (경계 내 일관성 보장)
- **State Machine**: EventStatus, JobStatus (상태 전이 제약)
- **Value Object**: StoreInfo, Customizations (불변 값)
### 7.2 Application 패턴
- **Service Layer**: EventService, JobService (유스케이스 조율)
- **DTO Pattern**: Request/Response 분리 (계층 간 데이터 전송)
- **Repository Pattern**: EventRepository (영속성 추상화)
### 7.3 Infrastructure 패턴
- **Adapter Pattern**: ContentServiceClient (외부 서비스 연동)
- **Producer/Consumer**: Kafka 메시징 (비동기 통신)
- **Cache-Aside**: Redis 캐싱 (성능 최적화)
---
## 8. 트랜잭션 경계
### 8.1 @Transactional 적용 위치
```java
EventService:
- createEvent() - 쓰기
- deleteEvent() - 쓰기
- publishEvent() - 쓰기
- endEvent() - 쓰기
- updateEvent() - 쓰기
- requestAiRecommendations() - 쓰기 (Job 생성)
- selectRecommendation() - 쓰기
- selectImage() - 쓰기
- selectChannels() - 쓰기
JobService:
- createJob() - 쓰기
- updateJobProgress() - 쓰기
- completeJob() - 쓰기
- failJob() - 쓰기
```
### 8.2 읽기 전용 트랜잭션
```java
@Transactional(readOnly = true):
- getEvent()
- getEvents()
- getJobStatus()
```
---
## 9. 보안 및 인증
### 9.1 인증 방식
- **개발 환경**: DevAuthenticationFilter (Header 기반)
- **운영 환경**: JWT 인증 (JwtAuthenticationFilter)
### 9.2 인가 처리
```java
@AuthenticationPrincipal UserPrincipal
- userId: 요청자 ID
- storeId: 매장 ID
검증:
- Event는 userId로 소유권 확인
- EventRepository.findByEventIdAndUserId() 사용
```
---
## 10. 에러 처리
### 10.1 공통 에러 코드
```java
ErrorCode:
- EVENT_001: 이벤트를 찾을 없음
- EVENT_002: 이벤트 수정/삭제 불가 (상태 제약)
- EVENT_003: 선택한 리소스를 찾을 없음
- JOB_001: 작업을 찾을 없음
- JOB_002: 작업 상태 변경 불가
```
### 10.2 예외 처리
```java
Domain Layer:
- IllegalStateException (상태 전이 제약 위반)
- IllegalArgumentException (비즈니스 규칙 위반)
Application Layer:
- BusinessException (비즈니스 로직 에러)
Infrastructure Layer:
- InfraException (외부 시스템 에러)
```
---
## 11. 테스트 전략
### 11.1 단위 테스트
```java
Domain Layer:
- Event 상태 전이 로직
- 비즈니스 규칙 검증
Application Layer:
- EventService 유스케이스
- DTO 변환 로직
```
### 11.2 통합 테스트
```java
Infrastructure Layer:
- Kafka Producer/Consumer
- Feign Client
- Redis 캐싱
Presentation Layer:
- REST API 엔드포인트
- 인증/인가
```
---
## 12. 파일 정보
### 12.1 다이어그램 파일
- **상세 다이어그램**: `design/backend/class/event-service.puml`
- **요약 다이어그램**: `design/backend/class/event-service-simple.puml`
### 12.2 참조 문서
- 공통 컴포넌트: `design/backend/class/common-base.puml`
- API 설계서: `design/backend/api/spec/event-service-api.yaml`
- 데이터 설계서: `design/backend/database/event-service-schema.sql`

# Participation Service 클래스 설계 결과
## 📋 개요
**Backend Developer (최수연 "아키텍처")**
Participation Service의 클래스 설계를 완료했습니다. Layered Architecture 패턴을 적용하여 이벤트 참여와 당첨자 추첨 기능을 담당하는 서비스를 설계했습니다.
## 🎯 설계 원칙 준수
### 1. 아키텍처 패턴
-**Layered Architecture** 적용
- Presentation Layer (Controller)
- Application Layer (Service, DTO)
- Domain Layer (Entity, Repository)
- Infrastructure Layer (Kafka, Config)
### 2. 공통 컴포넌트 참조
- ✅ BaseTimeEntity 상속 (Participant, DrawLog)
- ✅ ApiResponse<T> 사용 (모든 API 응답)
- ✅ PageResponse<T> 사용 (페이징 응답)
- ✅ BusinessException 상속 (ParticipationException)
- ✅ ErrorCode 인터페이스 사용
### 3. 유저스토리 및 API 매핑
- ✅ API 설계서와 일관성 유지
- ✅ Controller 메소드와 API 경로 매핑 완료
## 📦 패키지 구조

## 🏗️ 주요 컴포넌트
### Presentation Layer
#### ParticipationController
- **POST** `/events/{eventId}/participate` - 이벤트 참여
- **GET** `/events/{eventId}/participants` - 참여자 목록 조회
- **GET** `/events/{eventId}/participants/{participantId}` - 참여자 상세 조회
#### WinnerController
- **POST** `/events/{eventId}/draw-winners` - 당첨자 추첨
- **GET** `/events/{eventId}/winners` - 당첨자 목록 조회
### Application Layer
#### ParticipationService
**핵심 비즈니스 로직:**
- 이벤트 참여 처리
- 중복 참여 체크 (eventId + phoneNumber)
- 참여자 ID 자동 생성 (prt_YYYYMMDD_XXX)
- Kafka 이벤트 발행
- 참여자 목록/상세 조회
#### WinnerDrawService
**핵심 비즈니스 로직:**
- 당첨자 추첨 실행
- 가중치 추첨 풀 생성 (매장 방문 5배 보너스)
- 추첨 로그 저장 (재추첨 방지)
- 당첨자 목록 조회
### Domain Layer
#### Participant 엔티티
- 참여자 정보 관리
- 중복 방지 (UK: event_id + phone_number)
- 매장 방문 보너스 (5배 응모권)
- 당첨자 상태 관리 (isWinner, winnerRank, wonAt)
- 도메인 로직:
- `generateParticipantId()` - 참여자 ID 생성
- `calculateBonusEntries()` - 보너스 응모권 계산
- `markAsWinner()` - 당첨자 설정
#### DrawLog 엔티티
- 추첨 이력 관리
- 재추첨 방지 (eventId당 1회만 추첨)
- 추첨 알고리즘 기록 (WEIGHTED_RANDOM)
- 추첨 메타데이터 (총 참여자, 당첨자 수, 보너스 적용 여부)
### Infrastructure Layer
#### KafkaProducerService
- **Topic**: `participant-registered-events`
- 참여자 등록 이벤트 발행
- 비동기 처리로 메인 로직 영향 최소화
## 🔍 예외 처리
### ParticipationException 계층
1. **DuplicateParticipationException** - 중복 참여
2. **EventNotFoundException** - 이벤트 없음
3. **EventNotActiveException** - 이벤트 비활성
4. **ParticipantNotFoundException** - 참여자 없음
5. **AlreadyDrawnException** - 이미 추첨 완료
6. **InsufficientParticipantsException** - 참여자 부족
7. **NoWinnersYetException** - 당첨자 미추첨
## 🔗 관계 설계
### 상속 관계
```
BaseTimeEntity
├── Participant (domain.participant)
└── DrawLog (domain.draw)
BusinessException
└── ParticipationException
├── DuplicateParticipationException
├── EventNotFoundException
├── EventNotActiveException
├── ParticipantNotFoundException
├── AlreadyDrawnException
├── InsufficientParticipantsException
└── NoWinnersYetException
```
### 의존 관계
```
ParticipationController → ParticipationService
WinnerController → WinnerDrawService
ParticipationService → ParticipantRepository
ParticipationService → KafkaProducerService
WinnerDrawService → ParticipantRepository
WinnerDrawService → DrawLogRepository
KafkaProducerService → ParticipantRegisteredEvent
```
## 📊 데이터 처리 흐름
### 이벤트 참여 흐름
```
1. 클라이언트 → POST /events/{eventId}/participate
2. ParticipationController → ParticipationService.participate()
3. 중복 참여 체크 (existsByEventIdAndPhoneNumber)
4. 참여자 ID 생성 (findMaxSequenceByDatePrefix)
5. Participant 엔티티 생성 및 저장
6. Kafka 이벤트 발행 (ParticipantRegisteredEvent)
7. ParticipationResponse 반환
```
### 당첨자 추첨 흐름
```
1. 클라이언트 → POST /events/{eventId}/draw-winners
2. WinnerController → WinnerDrawService.drawWinners()
3. 추첨 완료 여부 확인 (existsByEventId)
4. 참여자 목록 조회 (findByEventIdAndIsWinnerFalse)
5. 가중치 추첨 풀 생성 (createDrawPool)
6. 무작위 셔플 및 당첨자 선정
7. 당첨자 상태 업데이트 (markAsWinner)
8. DrawLog 저장
9. DrawWinnersResponse 반환
```

- 자체 완결적인 도메인 로직
- 명확한 책임 분리
### 3. 이벤트 기반 통합
- Kafka를 통한 느슨한 결합
- 비동기 이벤트 발행
- 서비스 장애 격리
### 4. 가중치 추첨 알고리즘
- 매장 방문 보너스 (5배 응모권)
- 공정한 무작위 추첨
- 추첨 이력 관리
