Spring 에노테이션 기반 AOP

//공통모듈임을 나타내주어야함! 순서는 상관없음! aspect는 콤포논트의 확장된 버전이면

//상관없는데, 얘는 확장한 버전이 아니라 두개를 같이 써줘야함

@Aspect

@Component

public class LogAspect {

}

 

                  @Before(value="execution(* com.gorakgarak..*(java.lang.String))")

                  public void beforeLogging(JoinPoint joinPoint){

                                   System.out.println(joinPoint.getSignature().getName() + "메소드 호출 전 :" +

                                                                       joinPoint.getArgs()[0]);

                   }

 

 

둘다 해줘야함
