+### 6. 로깅 시스템
+
+#### @LogExecution 어노테이션 사용법
+
+**메서드 실행 로깅을 위한 필수 어노테이션입니다.**
+
+##### 기본 사용법
+
+```java
+@LogExecution("회원 등록")
+@PostMapping("/register")
+public ResponseEntity<ApiResponseDto<CreateMemberResponseDto>> createMember(@RequestBody CreateMemberRequestDto requestDto) {
+    // 메서드 실행 시 자동으로 로그 출력
+}
+```
+
+##### 로그 출력 예시
+
+**메서드 시작 시:**
+```
+[START] 회원 등록 | 호출경로: MemberController.createMember | 사용자: 고명빈(kmbin92)
+```
+
+**메서드 성공 시:**
+```
+[SUCCESS] 회원 등록 | 호출경로: MemberController.createMember | 사용자: 고명빈(kmbin92) | 시간: 200ms
+```
+
+**메서드 실패 시:**
+```
+[FAILED] 회원 등록 | 호출경로: MemberController.createMember | 사용자: 고명빈(kmbin92) | 시간: 23ms | 오류: 이미 존재하는 사용자 ID입니다
+```
+
+##### 어노테이션 설정
+
+```java
+@LogExecution("사용자 정보 조회")
+public UserDto getUserInfo() { }
+
+@LogExecution("주문 처리")
+public OrderDto processOrder() { }
+```
+
+##### 로깅 시스템 구성
+
+1. **MethodExecutionLoggingAspect**: 메서드 실행 로깅 (AOP)
+2. **HttpLoggingFilter**: HTTP 요청/응답 로깅 (필터)
+3. **logback-spring.xml**: 로그 파일 관리 및 설정
+
+**중요**: `@LogExecution` 어노테이션이 없으면 메서드 실행 로그가 출력되지 않습니다
