Walkthrough

채팅 전송 흐름이 변경되었습니다. 컨트롤러의 엔드포인트가 /chat/send 로 바뀌고 roomId를 요청 본문에서 읽습니다. Redis 게시 메서드는 예외를 호출자에게 전파하며 디버깅 출력이 추가되었습니다. Redis 리스너는 chat/* 토픽을 구독하고, 수신 메시지를 /chat/{id}로 브로드캐스트합니다.

Changes

Poem

작은 발로 키보드 탁탁, hop-hop, 코드 춤춰요 🐇
경로는 새로, 예외는 위로, 채널은 chat으로!
Redis에 속삭이고, 소켓에 전해요—슝—
메시지 씨앗 틔워, 방마다 봄바람 불게.
오늘도 깡총, 배포는 성공!
