逆向工程的使用

public List<TbUsers> login(TbUsers users) {
		// TODO Auto-generated method stub
		//其实只返回一行（user）
		//根据username和password选择除list
		TbUsersExample example = new TbUsersExample();
		Criteria criteria = example.createCriteria();
		criteria.andUsernameEqualTo(users.getUsername());
		criteria.andPasswordEqualTo(users.getPassword());
		List<TbUsers> list = tbUsersMapper.selectByExample(example);
		return list;
	}
	//修改user
	public int updTbUsers(TbUsers users) {
		// TODO Auto-generated method stub
		return tbUsersMapper.updateByPrimaryKeySelective(users);
	}
