[SPRING] 스프링 문제가있는 Ajc 컴파일러 사용하기 AspectJ

스프링 문제가있는 Ajc 컴파일러 사용하기 AspectJ

내가 ajc 컴파일러를 사용하여 스프링으로 aspectj를하려고 할 때, 나는 aspectj을 제거하고 errror.when을 따르고있다. 그리고 코드는 잘 동작한다. 컴파일 시간에 짜증나는 문제가있다.

해결법

1. ==============================

   1.76 번 라인이 어떤 것인지 알지 못하면 어렵습니다.

   76 번 라인이 어떤 것인지 알지 못하면 어렵습니다.

   at com.cdf.dfdxc.aspect.logging.LoggingAspect.logEntry(LoggingAspect.java:76)
   

   하지만 당신은 매우 공격적인 pointcut을 사용하고 있습니다.

   @Pointcut("within(com.csc.exceed.uow.*)")
   public void loggingAspect() {}
   

   이는 메소드 실행뿐 아니라 정적 및 인스턴스 초기화 도구, 필드 액세스 등과 같은 모든 종류의 이벤트와 일치합니다 (AspectJ 빠른 참조의 Primitive Pointcuts 개요 참조).

   다음 중 하나 일 경우 :

   이 중 76 번 라인에서 어떤 것이 발생하는지 확인하고 실패한 후보자를 찾으십시오. 하지만 내 첫 번째 힌트는 적극적인 catch-all pointcut을 실행 또는 call pointcut으로 대체하는 것입니다.

   모듈 방식으로 정의 된 결합 된 pointcut을 사용합니다.

   // you can easily reuse this
   @Pointcut("within(com.csc.exceed.uow.*)")
   public void myApp() {}
   
   // and this
   @Pointcut("execution(* *.*(..))")
   public void methodExecution(){}
   
   // but this is the pointcut you are actually matching
   @Pointcut("myApp() && methodExecution()")
   public void methodExecutionInMyApp(){}
   
   @Before("methodExecutionInMyApp()")
   public void logMethodExecutions(JoinPoint jp){
       // your code here
   }
   

   NPE 안전 클래스를 만드는 방법은 다음과 같습니다.

   Class<?> clazz = joinPoint.getTarget() !=null 
                  ? joinPoint.getTarget().getClass() 
                  : null;
