feat(chat): 채팅방 채팅 메세지 전달 로직 디버깅 (#78)

[jaehyeok-code]

Summary by CodeRabbit

• Refactor
  • 채팅 메시지와 알림을 WebSocket을 통해 토픽으로 직접 송신하도록 전송 경로를 단순화했습니다.
  • 컨트롤러와 서비스에서 중간 브로커 의존을 제거해 실시간 전달 흐름을 일원화했습니다.
  • 결과적으로 메시지·알림이 더 즉시 전송되며 전송 지연이 완화될 수 있습니다.

Walkthrough

Redis 기반 채팅 경로를 전면 비활성화하고, STOMP WebSocket 직접 전송으로 전환. Redis 관련 @Component/@configuration 등록을 주석 처리하고, 컨트롤러와 서비스에서 Redis 퍼블리시 호출을 제거하여 messagingTemplate.convertAndSend(...)로 즉시 브로드캐스트하도록 변경.

Changes

Cohort / File(s)	Summary of changes
Redis 구성요소 비활성화 .../domain/chat/bus/ChatRedisPublisher.java, .../domain/chat/bus/ChatRedisSubscriber.java, .../domain/chat/bus/RedisPubSubConfig.java	클래스의 Spring 등록 비활성화: @Component/@Configuration를 주석 처리하여 빈 등록 중단. 나머지 로직은 유지되나 사용 경로에서 배제.
메시징 컨트롤러 전송 경로 전환 .../domain/chat/controller/ChatMessagingController.java	Redis 퍼블리시 의존성/호출 제거(주석). /topic/chat/{roomId}로 messagingTemplate.convertAndSend(...) 직접 호출로 교체.
알림 컨트롤러 전송 경로 전환 .../domain/chat/controller/ChatNotificationController.java	Redis 퍼블리시 의존성/호출 제거(주석). WebSocket 직접 브로드캐스트로 통일.
알림 서비스 전송 경로 전환 .../domain/chat/service/Impl/ChatNotificationServiceImpl.java	chatRedisPublisher.publishToRoom(...) 제거(주석) 후 messagingTemplate.convertAndSend(...) 즉시 전송으로 일원화. 트랜잭션/저장 로직은 유지.

Poem

토끼는 채팅 버스를 살짝 접고, 홉!
레디스 숲은 잠시 쉬고, 웹소켓 길로 쏙—
메시지는 즉시 둥실 떠가네.
방마다 톡톡, 종소리처럼 전해져,
귀를 쫑긋, “지금 바로!” 띵동! 🥕✨
