项目介绍
用于餐厅的收银管理系统，包含了四个模块
1.桌位模块
桌位模块主要是用于管理桌位的模块，包括点菜到结账的流程
将桌位人数设置为`0`可以滞空当前桌位
2.账单模块
账单模块记录了每一天的帐单汇总，同时提供了年月日账单的统计，在日账单内可以查看当日的所有消费详情，还提供了按日期或日期区间搜索账单的功能
3.日常维护模块
提供了桌位菜单用户供应商的配置功能，也就是增删改查
添加菜品时，添加酒水类时，可以选择进货内的酒水，这样的话在结账后若客人点了该酒水，会将销售信息记录在酒水库存内的销售信息里
4.酒水库存模块
查看添加酒水的进销存信息
管理员角色包含以下功能：
登录,查看桌位,开桌,点菜,结账,查看账单,添加菜品,查看菜品,桌位维护,添加桌位,添加账号,查看账号,添加供应商,进货信息管理,添加进货信息等功能。
环境需要
1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.数据库：MySql 5.7版本；
6.是否Maven项目：否；
7.Redis数据库;
技术栈
1. 后端：Spring+SpringMVC+Mybatis
2. 前端：JSP+Bootstrap+jQuery
使用说明
1. 使用Navicat或者其它工具，在mysql中创建对应名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，Eclipse/MyEclipse导入时，若为maven项目请选择maven;若为maven项目，导入成功后请执行maven clean;maven install命令，然后运行；
3. 将项目中applicationcontext-mybatis.xml配置文件中的数据库配置改为自己的配置;
4. 运行项目，输入localhost:8080/login.html 登录
管理员账号/密码：admin/adminadmin
