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；

技术栈

JSP+CSS+JavaScript+html+mysql+servlet

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dao/DBUtils.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/meeting/ 注：Tomcat中配置路径必须为meeting,否则会有异常；
