📝 WalkthroughWalkthrough접근 로깅 시스템이 추가되었습니다. 도메인 모델(AccessLog, AccessLogEvent), 이벤트 처리 인프라(Events, EventsConfiguration, AsyncConfig), HTTP 필터(MdcLoggingFilter)는 요청 메타데이터를 캡처하고 이벤트를 발행하며, 출력 포트 및 어댑터 패턴은 영속성을 제공하고, MDC 구성은 요청 상관관계를 설정하고, 중앙화된 로깅 구성을 도입합니다. Changes

- Line 8: The AccessLog data class exposes the raw uri property which may
contain sensitive query parameters; update where AccessLog(uri: String, ...) is
created to pass a sanitized value instead and add a utility like
sanitizeUri(uri: String): String (or a companion/object helper) that either
strips the query string or masks known sensitive keys (e.g., token, password,

ensure any persistence path (Elasticsearch/DTO mapping) uses the sanitizedUri
output rather than the raw input to meet privacy requirements.

`@linktrip-input-http/src/main/kotlin/com/linktrip/input/http/filter/MdcLoggingFilter.kt`:
- Line 35: The current low-entropy requestId is created in MdcLoggingFilter via
MDC.put(MdcKey.REQUEST_ID, UUID.randomUUID().toString().substring(0, 8)), which
risks collisions under high traffic; change this to a higher-entropy value (for
example use the full UUID string UUID.randomUUID().toString() or a longer
substring like first 16+ hex chars, or a base64/hex-encoded random 12+ byte
value) in the MDC.put call so MdcKey.REQUEST_ID has sufficient uniqueness for
correlation tracking.
- Around line 52-53: The access log call in raiseAccessLogEvent is using a
hardcoded 500 on exception paths, which can misrepresent the actual response
status; update the exception handling in MdcLoggingFilter (reference:
raiseAccessLogEvent and the catch/exception block) to determine and pass the
real response status (e.g., obtain status from the HttpServletResponse or the
request/response context) instead of the literal 500, falling back to 500 only
if the actual status cannot be retrieved.
- Around line 80-83: The getClientIp method in MdcLoggingFilter currently trusts
X-Forwarded-For and X-Real-IP without verification, so either enable and rely on
Spring’s forwarded headers handling or validate headers against a trusted proxy
list: add server.forward-headers-strategy in application.yml or register
ForwardedHeaderFilter (or implement explicit trusted proxy IP range checks) and
then update getClientIp to only read X-Forwarded-For/X-Real-IP when the
forwarded-header mechanism is active or when request.remoteAddr is in your

the chosen fix.

URI에 민감한 정보가 포함될 수 있습니다.
쿼리 파라미터에 토큰, 이메일 등 민감한 정보가 포함될 수 있으므로, 로그 저장 전 URI 필터링이 필요할 수 있습니다. 추후 Elasticsearch 등에 저장할 때 개인정보 보호 규정(GDPR/CCPA) 준수 여부를 확인하세요.
