作者主页：夜未央5788

 简介：Java领域优质创作者、Java项目、学习资料、技术互助

文末获取源码

项目介绍

主要功能包括：

登陆页,房间信息,房间管理,开取房间,房间查询,会员管理,食物管理,查看订单,查询订单,查看房间消费使用情况等功能。

由于本程序规模不大，可供课程设计，毕业设计学习演示之用

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；

技术栈

1. 后端：Spring+SpringMVC+Mybatis

2. 前端：HTML+CSS+JavaScript+jsp

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application.yml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/ 登录
