基于javaweb+mysql的jsp+servlet地下停车场管理系统(java+jsp+jquery+servlet+mysql)

私信源码获取及调试交流

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

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的JSP+Servlet地下停车场管理系统(java+jsp+jquery+servlet+mysql)

项目介绍

本项目包含管理员与普通用户两种角色;

管理员角色包含以下功能: 管理员登录,添加角色信息,管理角色信息,添加用户信息,管理用户信息,车位信息管理,IC卡信息管理,出入库管理,停车信息管理,临时车辆入库管理,车辆出库管理,修改密码等功能。

用户角色包含以下功能: 用户登录,临时车辆入库管理,车辆出库管理,修改密码,修改个人信息等功能。

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.数据库:MySql 5.7版本; 6.是否Maven项目: 否;

技术栈

  1. 后端:servlet 2. 前端:JSP+Javascript+css+jQuery

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db.properties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/ 用户账号/密码:user/123456 管理员账号/密码:admin/admin
