Advice 타입 별 클래스 작성 - 여러 Advice에 동일한 Pointcut 참조

<aop:pointcut> 태그와 각 Advice 설정 태그의 pointcut-ref 속성을 이용해서 Pointcut을 설정하고 여러 Advice에서 동일한 Pointcut을 참조

 

 

FaqBoardImpl.java

package sp.aop.service; import org.springframework.stereotype.Component;   @Component("faqBoard") public class FaqBoardImpl implements Board {  @Override  public String getBoardName() {   // TODO Auto-generated method stub   return "FAQ Board";  }  @Override  public String checkBoard() {   // TODO Auto-generated method stub   return "N";  } }

 

NoticeBoardImpl.java

package sp.aop.service; import org.springframework.stereotype.Component;   @Component("noticeBoard") public class NoticeBoardImpl implements Board {  @Override  public String getBoardName() {   // TODO Auto-generated method stub   return "Notice Board";  }  @Override  public String checkBoard() {   // TODO Auto-generated method stub   return "Y";  } }

 

BoardController.java

LogAdvice.java

package sp.aop.advice; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.ProceedingJoinPoint;   public class LogAdvice {    public Object logPrint(ProceedingJoinPoint joinPoint) throws Throwable{   System.out.println("***** START *****");   try{    System.out.println("*");    System.out.println("**");        Object ret = joinPoint.proceed();        System.out.println("***");    System.out.println("****");        return ret;   }finally{    System.out.println("***** END *****");   }  }    public void before(JoinPoint joinPoint){   System.out.println("***** before *****");  }    public void afterReturning(Object obj){   System.out.println("***** after-returning *****");   System.out.println("obj : " + obj.toString());  }    public void afterThrowing(Throwable exp){   System.out.println("***** after-throwing *****");   System.out.println("ex : " + exp.toString());  }    public void afterFinally(JoinPoint joinPoint){   System.out.println("***** after finally *****");   System.out.println("joinPoint : " + joinPoint.toString());  }   }
