为什么它要回滚...您自己打开新会话，也自己管理事务。Spring怎么会知道。

你的daos在很多方面都是错误的。

1. 永远不要将会话/事务存储在实例变量中
2. 使用Spring管理事务时，请不要使用OpenSession
3. 如果需要容器管理事务，请不要管理自己的事务。

public class CustomerDaoServiceImpl implements CustomerDaoService{
    @Autowired
    SessionFactory sessionFactory;

    @Override
    public boolean saveCustomer(Customer customer) throws Exception {
        Session session = sessionFactory.getCurrentSession();
        session.save(customer);
        return false;
    }
}
