Day 70 : 트랜잭션 처리

1. 트랜잭션 tx 네임스페이스 등록

 

2. 트랜잭션 관리자 등록 - DataSourceTransactionManager 클래스 <bean> 등록

- 스프링 설정 파일

3. 트랜잭션 어드바이스 설정 - <tx:advice> 엘리먼트 사용

속성	의미
name	트랜잭션이 적용될 메소드 이름 지정
read-only	읽기 전용 여부 지정 (기본값 false. true일 경우 트랜잭션 관리 대상에서 제외)
no-rollback-for	트랜잭션을 롤백하지 않을 예외 지정
rollback-for	트랜잭션을 롤백할 예외 지정

4. AOP 설정을 통한 트랜잭션 적용 - <aop:aspect>가 아닌 <aop:advisor> 사용

: 트랜잭션 어드바이스 클래스는 직접 구현하지 않고 <tx:advice> 설정으로 스프링 컨테이너가 자동 생성함 → 결국, 어드바이스 메소드의 이름을 모르기 때문에 <aop:aspect>는 사용할 수 없음
