		UserDAOImpl userDao = new UserDAOImpl();
		User user = userDao.getUserByloginId(loginId);
		
		System.out.println("loginId is:" + loginId);
		
		//是否存在用户
		if (user != null) {
			// 业务逻辑，判断密码，是否与输入的密码一致
			if (user.getPassword().equals(password)) {
				return user;
			}
		}
		
		return null; //暂时处理
	}
	/**
