PATCH /auth/apple/sync) 시 Access Token이 만료된 상태라면 Security Filter Chain에서401 Unauthorized가 발생2. 해결 방안 (TO-BE)
만료된 토큰이라도 사용자 식별(User ID) 만 가능하다면 연동 로직을 수행할 수 있도록 변경했습니다.
SecurityConfig.java:/auth/apple/sync경로를permitAll()로 설정하여 Security Filter의 토큰 만료 검증을 우회하도록 수정JwtProvider.java:getUserIdFromExpiredToken()메서드 추가Jwts.parserBuilder()실행 시ExpiredJwtException이 발생하더라도, 예외 객체 내의Claims를 조회하여userId를 추출하도록 구현AuthController.java:@AuthenticationPrincipal은 유효한 토큰일 때만 동작하므로 제거@RequestHeader("Authorization")을 통해 토큰 문자열을 직접 받아, 위에서 구현한 파싱 메서드로 유저를 식별하도록 변경To Reviewers
