어노테이션 먼저 정리
1. @Before
- 설명: 지정된 포인트컷 이전에 실행되는 어드바이스
2. @After
- 설명: 지정된 포인트컷 후에 실행되는 어드바이스 메소드 실행 여부와 관계없이 항상 실행
3. @AfterReturning
- 설명: 지정된 포인트컷의 메소드가 정상적으로 실행된 후에 실행되는 어드바이스 메소드가 예외 없이 정상적으로 종료되었을 때만 실행
4. @AfterThrowing
- 설명: 지정된 포인트컷의 메소드가 예외를 던졌을 때 실행
5. @Around
- 설명: 지정된 포인트컷 전후로 실행되며, 메소드의 실행을 제어 @Before와 @After를 합친 효과를 제공 ProceedingJoinPoint를 이용하여 메소드 실행을 직접 제어 가능
6. @Pointcut
- 설명: 어드바이스가 적용될 포인트컷 표현식을 정의하는 어노테이션 다른 어드바이스에서 사용될 수 있도록 포인트컷을 재사용 가능 일종의 AOP 타겟 alias 한다고 생각하면 쉽다
7. @EnableAspectJAutoProxy
- 설명: Spring에서 AOP 기능을 활성화하려면 @EnableAspectJAutoProxy 어노테이션을 추가해야 한다.
EnableAspectJAutoProxy는 Spring AOP를 활성화하고, AspectJ 스타일의 AOP 기능(포인트컷, 어드바이스 등)을 프록시 기반으로 사용할 수 있게 해주는 어노테이션 으로
스프링 부트에서는 spring-boot-starter-aop 의 영향으로 저 어노테이션을 붙인 config 파일을 생성하지 않아도 된다
본인은 해당 게시물에서 파일을 생성하지 않고 예제를 생성하였다. - 사용할 경우 예시 ↓

@Pointcut 표현식에서 사용되는 주요 키워드
- execution(): 메소드 실행 시점을 포인트컷으로 지정
- 예시: execution(* com.example.service.*.*(..)) (모든 메소드)
- within(): 특정 클래스나 패키지 내에서 실행되는 메소드에 적용
- 예시: within(com.example.service.*) (service 패키지 내 모든 클래스의 메소드)
- args(): 메소드의 파라미터 타입을 기준으로 포인트컷을 지정
- 예시: args(java.lang.String) (String 타입 파라미터를 받는 메소드)
- @annotation(): 특정 어노테이션이 적용된 메소드에 적용
- 예시: @annotation(org.springframework.transaction.annotation.Transactional) (Transactional 어노테이션이 적용된 메소드)
- this(), target(): 프록시 객체와 대상 객체를 기준으로 포인트컷을 설정
