[Tip] Spring AOP로 트랜젝션 설정하기

1. XML에 AOP 트랜젝션을 설정하기

dataSource 설정과 같은 LEVEL의 XML에 설정해야만 AOP 기반의 트랜젝션이 정상 동작함을 확인함..

2. Service 클래스 작성하기

Service 클래스의 메서드에서 try-catch로 예외를 처리하게 되면 트랜젝션이 동작하지 않음. Controller까지 예외가 전달되도록 구조를 잡아야 함.

 

@Service
public class TestService {
    
    Logger logger = LoggerFactory.getLogger(TestService.class);
    
    @Autowired
    private TestDAO testDao;
    
    
    public void insert(Map<String, Object> paramMap) throws Exception {
        int insertCount = testDao.insert(paramMap);
        if (insertCount <= 0)
            throw new Exception();
    }
}
