基于javaweb+mysql的jsp+servlet聚会会议室预约体系(java+jsp+bootstrap+servlet+mysql)运行环境
Java≥8、MySQL≥5.7、Tomcat≥8
开发工具
eclipse/idea/myeclipse/sts等均可设置运行
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+mysql的JSP+Servlet聚会会议室预约体系(java+jsp+bootstrap+servlet+mysql)
项目先容
网上聚会会议室预约体系,该项目是一个前背景的项目；
前台重要功能有： 登录、注册； 首页、预约须知； 聚会会议室预约； 聚会会议室信息； 聚会会议室预约表； 背景重要功能有： 通告栏：查看、添加、修改、删除； 聚会会议室信息：查看、添加、修改、删除； 查看登记表； 查看预约消息；
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.是否Maven项目: 否；查看源码目次中是否包含pom.xml；若包含，则为maven项目，否则为非maven项目 6.数据库：MySql 8.0版本；
技术栈
[*]后端：Servlet 2. 前端：JSP+bootstrap+jQuery
使用说明
[*]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druid.properties设置文件中的数据库设置改为自己的设置 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下令，设置tomcat，然后运行； 4. 运行项目， 前台运行地点：http://localhost:8080/index.jsp 登录 背景运行地点：http://localhost:8080/back/index.jsp 登录
