javaSwing酒店管理
一、介绍
在这篇博客中，我们将介绍一个基于MySQL数据库、Java编程语言和Swing图形用户界面的简单酒店管理系统。该系统包括了查询房客信息、查询房客状态、修改房客信息、添加房间信息、添加住户、退房管理、预定管理、退订管理、入账管理、出账管理、修改资料等多个功能。
二、数据库介绍

字段解释：
id: 预订编号，主键。
name: 预订人姓名。
phone: 预订人电话。
checkTime: 预订入住时间。
creditTime: 订单创建时间。
state: 预订状态（已退订等）。
t_cashier（收支信息表）：

type: 客房类型。
3.t_household（住户信息表）：
记录入住和退房的住户信息，包括姓名、身份证号、入住时间、房间号等。
字段解释：
id: 住户编号，主键。
name: 住户姓名。
idNum: 身份证号码。
checkTime: 入住时间。
roomNum: 入住房号。
money: 收费金额。
state: 入住状态。
outTime: 退房时间。
4.t_user（用户信息表）：
存储系统用户的登录名和密码。
字段解释：
id: 用户编号，主键。
userName: 登录名。
password: 登录密码。
