基于javaweb+mysql的校园一卡通系统(java+JSP+Servlet+html+css+JavaScript+JQuery+Ajax+mysql)

本文主要是介绍基于javaweb+mysql的校园一卡通系统(java+JSP+Servlet+html+css+JavaScript+JQuery+Ajax+mysql)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、项目简述
功能：卡管理，卡消费，卡充值，图书借阅，消费，记录，注销等等功能。

二、项目运行

环境配置：

Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

项目技术：

JSP + Servlet + html+ css + JavaScript + JQuery + Ajax 等等请添加图片描述

适用

课程设计，大作业，毕业设计，项目练习，学习演示等
