基于javaweb+mysql的jsp+servlet酒店管理系统(java+jsp+bootstrap+jquery+servlet+mysql)

私信源码获取及调试交流

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb的JSP+Servlet酒店管理系统(java+jsp+bootstrap+jquery+servlet+mysql)

项目介绍

该项目主要分为酒店管理员与操作员两种角色； 酒店管理员角色包含以下功能： 管理员登录,用户管理、住客信息管理、客房管理、房间管理、会员等级折扣管理、订单管理等功能。

操作员角色包含以下功能： 用户登录,用户管理、住客信息管理、房型管理、房间管理、订单管理等功能。

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；查看源码目录中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目

技术栈

  1. 后端：Servlet 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link/DBUtil.java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 酒店管理员账号/密码：admin/admin 操作员账号/密码：aa/aa
