Advice 타입 별 클래스 작성 - 여러 Advice에 동일한 Pointcut 참조

영혼과영혼의양식 2012. 5. 5. 20:30

<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

package sp.aop.controller;

import javax.annotation.Resource;

 @Resource(name="noticeBoard")
 private Board board;
 
 @Override
 protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
   HttpServletResponse arg1) throws Exception {
  // TODO Auto-generated method stub
  
  System.out.println("<<===== START =====>>");
  System.out.println("Board Name-1 : " + board.getBoardName());
  System.out.println("");
  System.out.println("Board Check-1 : " + board.checkBoard());
  System.out.println("<<===== END =====>>");
  
  return null;
 }

}

 

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());
 }
 
}
