[ Spring ] AOP ( Aspect Oriented Programming ) - excepObj를 통하여 반환된 예외 확인하기

 

AfterThrowingAdvice

Target 메서드가 수행도중 예외가 발생했을 때 되면 실행되는 Advice를 의미한다.

 

---

 

1. Exception excepObj를 추가한다.

package com.test.app.common;

import org.aspectj.lang.JoinPoint;

public class AfterThrowingAdvice {	 // ▼ 
	public void ataLog(JoinPoint jp, Exception excepObj) {
									// 반환받을 예외 객체
		String methodName = jp.getSignature().getName();
		System.out.println("호출된 핵심관심: " + methodName);
	}
}

 

 

 

2. XML 파일을 아래와 같이 수정해준다.

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd">

	<context:component-scan base-package="com.test.app"/>

	<bean id="log" class="com.test.app.common.LogAdvice"/><!-- 사용될 클래스 new처리 -->
	
	<aop:config>
		<aop:pointcut expression="execution(* com.test.app..*Impl.*(..))" id="aPointCut"/>
		<aop:aspect ref="log">
			<aop:after-throwing method="printlog1" pointcut-ref="aPointCut" throwing="excepObj"/><!-- excepObj -->
		</aop:aspect>
	</aop:config>
	
</beans>

 

 

3. BoardServiceImpl에서 일부러 예외를 발생시키는 코드를 작성해준다.

 

public class BoardServiceImpl implements BoardService {

   private BoardDAO boardDAO;
   
   @Override
   public void insertBoard(BoardVO vo) {
      if(vo.getBid()==0) {
         throw new IllegalArgumentException("내가 만든 예외!");
      }
      boardDAO.insertBoard(vo);
   }

 

 

 

4.  client에서 실행시키고 값을 확인 하면 끝!
