在Spring 3/Hibernate中回滚事务的最佳实践

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
   <property name="sessionFactory" ref="sessionFactory" />
</bean>

@Service
public class MyService {

    @Autowired
    private UserDao userDao;

    @Transactional
    public void createUser(User user) {
        userDao.createUser(user);
    }
}

@Service
public class MyService {

    @Autowired
    private UserDao userDao;

    @Autowired
    private PlatformTransactionManager transactionManager;

    public void createUser(User user) {
        TransactionTemplate transactionTemplate = new TransactionTemplate(transactionManager);
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {
            @Override
            protected void doInTransactionWithoutResult(TransactionStatus status) {
                try {
                    userDao.createUser(user);
                } catch (Exception ex) {
                    status.setRollbackOnly();
                }
            }
        });
    }
}
