[스프링AOP] 스프링AOP 구현 - Pointcut 참조

다음과 같이 포인트컷을 공용으로 사용하기 위해 별도의 외부 클래스에 모아두어도 된다. 

참고로 외부에서 호출할 때는 포인트컷의 접근 제어자를 public 으로 열어두어야 한다.

 

1. Pointcuts

---

import org.aspectj.lang.annotation.Pointcut;

public class Pointcuts {

    //hello.aop.order 패키지와 하위 패키지
    @Pointcut("execution(* hello.aop.order..*(..))")
    public void allOrder(){ } // pointcut signature

    //클래스 이름 패턴이 *Service
    @Pointcut("execution(* *..*Service.*(..))")
    public void allService(){}

    //allOrder() && allService()
    @Pointcut("allOrder() && allService()")
    public void orderAndService(){}
}

 

 

2. AspectV4

---

@Slf4j
@Aspect
public class AspectV4Pointcut {

    @Around("hello.aop.order.aop.Pointcuts.allOrder()")
    public Object doLog(ProceedingJoinPoint joinPoint) throws Throwable{
        log.info("[[log] {}", joinPoint.getSignature());
        return joinPoint.proceed(); //target호출
    }

    //hello.aop.order 패키지와 하위 패키지이면서, 클래스 이름 패턴이 *Service
    @Around("hello.aop.order.aop.Pointcuts.orderAndService()")
    public Object doTransaction(ProceedingJoinPoint joinPoint) throws Throwable{
        try{
            log.info("[트랜잭션 시작] {}", joinPoint.getSignature());
            Object result = joinPoint.proceed();
            log.info("[트랜잭션 커밋] {}", joinPoint.getSignature());
            return result;
        }catch (Exception e){
            log.info("[트랜잭션 롤백] {}", joinPoint.getSignature());
            throw e;
        }finally {
            log.info("[리로스 릴리즈] {}", joinPoint.getSignature());
        }
    }
}

• 사용하는 방법은 패키지명을 포함한 클래스 이름과 포인트컷 시그니처를 모두 지정하면 된다.
• 포인트컷을 여러 어드바이스에서 함께 사용할 때 이 방법을 사용하면 효과적이다.
