一、系统介绍

该系统包含数据库，论文，任务书，开题报告，请在下载源码中下载！！！

走过路过不要错过，点赞加关注的脱单暴富，走上人生巅峰！！！

1.开发环境

开发工具：IDEA.2

JDK版本：jdk1.8

Mysql版本：8.0.13

2.技术选型

后端：Java+Servlet进行开发。

前端：JSP+HTML+CSS。

3.系统功能

基于Web停车场管理系统主要用于实现停车场相关信息管理，基本功能包括：系统信息管理模块、车位信息管理模块、IC卡信息管理模块、固定车主停车管理模块、临时车辆信息管理模块、系统功能操模块等。本系统结构如下：

(1)系统信息管理模块：角色的增加、删除、修改和查询；用户的增加、删除、修改和查询。

(2)车位信息管理模块：车位信息的增加、删除、修改和查询。

(3)IC卡信息管理模块：IC卡信息的增加、删除、修改和查询。

(4)固定车主停车管理模块：对固定车主的停车信息进行增加、删除、修改和查询

(5)临时车辆信息管理模块：对临时车辆的停车信息进行增加、删除、修改、查询和打印

(6)系统功能操模块：退出登陆、修改密码。
