酒店管理系统-温情小筑后台管理系统

系统概要

项目主要功能包括：

住客管理：住客入住、住客列表；

房间管理：房间列表、添加房间、修改房间状态；

会员管理：新增会员、会员列表；

系统设置：网站信息、修改密码、清除缓存；

数据表：生成Excel并导出等功能，适合java新手学习；

技术选型

1.后台技术选型：SSM（Spring SpringMVC Mybatis）

2.前端技术选型：LayUI

开发环境

1.编程语言：Java

2.开发工具：IDEA/Eclipse、Navicat

3.项目构建：Maven 3.5.2

4.服务器：Tomcat 8.0及以上

5.数据库：MySQL5.7

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. 将项目中jdbc.properties配置文件中的数据库配置改为自己的配置;

3. 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，配置tomcat，然后运行；

4. 运行项目，输入localhost:8080/ 登录

运行

导入项目并运行成功后，在tomcat路径中设置为/,注意路径中不要带有项目名，否则会导致项目运行异常；
