基于Java的学生会管理系统

项目技术：

后端：servlet

前端：bootstrap,kindeditor,js,css,Ajax等

开发工具：eclipse

数据库：mysql 5.7

JDK版本：jdk1.8

服务器：tomcat8

项目介绍：

该系统采用java语言，servlet开发，mysql数据库，适合基础一般的学生使用。系统分为两个角色，分别为管理员、学生会会员，包含参考论文。功能包含：学生会公共信息查看、活动了解、也可以注册会员、注册的会员可以发布活动，活动需要管理员审核，并且可以维护个人信息、管理员可以发布公告信息、活动审核等，其中发布信息可以包含文字、图片等信息。
