spring 2.5 에서 transaction(트랜잭션) 걸기

 < Spring 2.5 >

 트랜잭션이 안되서 한참 삽질을 한 결과

 책이나 다른 웹에서도 알려주지 않았던 중요한 사실을 하나 알았는데...

 <aop:config>
  <aop:pointcut id="serviceOperation" expression="execution(* *..service.*.*(..))"/>
  <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation"/>
 </aop:config> 

 
이 설정을 applicationContext.xml 파일에 만들었는데

 aop를 적용할 빈이 있는 설정 파일(여기서는 service.xml) 에 두어야 한다.

< Spring 에서 AOP방식으로 Transaction 을 걸기 위해서는 다음의 라이브러리가 필요하다. >

spring-framework-2.5.6.SEC01-with-dependencies\spring-framework-2.5.6.SEC01\lib\aspectj

 * aspectj/aspectjweaver.jar, aspectj/aspectjrt.jar, (aspectj/aspectjtools.jar)
- AspectJ 1.6.2 (http://www.aspectj.org)
- required for building the framework
- required at runtime when using Spring's AspectJ support

spring-framework-2.5.6.SEC01-with-dependencies\spring-framework-2.5.6.SEC01\lib\cglib

* cglib/cglib-nodep-2.1_3.jar
- CGLIB 2.1_3 with ObjectWeb ASM 1.5.3 (http://cglib.sourceforge.net)
- required for building the framework
- required at runtime when proxying full target classes via Spring AOP

이 라이브러리를 추가하지 않고서 WAS를 기동시켰을 때 에러가 나야지만 제대로 AOP 설정이 된 것이라고 볼 수 있다.

설정이 잘 못 되서 AOP가 인식안되면 처음 WAS 기동 시 에러가 나지 않음.

설정이 잘 되어 있는지 확인하는 방법

 <tx:advice id="txAdvice" transaction-manager="transactionManager">
  <tx:attributes>
   <tx:method name="*" propagation="MANDATORY"   rollback-for="Exception" />
  </tx:attributes>
 </tx:advice>

 위와 같이 propagation="MANDATORY"  로 한번 걸어본다.

 그러면 웹어플리케이션이 기동하고 나서 DB 접속 시 다음과 같이 에러가 나야 한다.
