Hibernate+Struts+Spring整合集成用户登录代码

最近前一个月学完了Hibernate+Struts+Spring框架,今天无聊就试着做了些经常到的功能.
下面是整合集成用户登录代码:

public int checkLogin(final String username, final String password) {
		
		int flag = 0;
		try {
			User user = null;
			Session session = this.getHibernateTemplate().getSessionFactory()
					.openSession();
			Query q = session
					.createQuery("from User u where username=:name and password=:pass");
			q.setString("name", username);
			q.setString("pass", password);
			List l = q.list();
			if (l.size() > 0) {
				user = (User) l.get(0);
				flag = 1;
			}
			
		} catch (HibernateException e) {
			
			e.printStackTrace();
		}
		return flag;
	}
