[Spring] Spring 프레임워크(10) - 트랜잭션과 로깅

[스프링 트랜잭션]

주로 서비스 메서드를 대상으로 진행

 

- 선언적 트랜잭션

1. 어노테이션을 이용한 선언적 방식

• root-context.xml에 Transaction Manager와 <tx:annotation-driven ../> 설정
• 트랜잭션이 필요한 클래스나 메소드에 @Transactional 어노테이션 추가

2. AOP를 이용한 선언적 방식

• 트랜잭션 매니저 설정
• 트랜잭션 어드바이스 설정: <tx:acvice..>
• AOP설정: <aop:config>

[Logging Tool]

-Logging Tool

commons-logging, log4j, logback등 툴이 있다.

SLF4J과 Logback의 비중이 늘고 있다.
