基于javaweb+mysql的jsp+servlet在线奶茶店系统(java+jsp+javascript+servlet+mysql)_基于java的奶茶店管理系统

基于javaweb+mysql的jsp+servlet在线奶茶店系统(java+jsp+javascript+servlet+mysql)

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+mysql的JSP+Servlet在线奶茶店系统(java+jsp+javascript+servlet+mysql)

项目介绍

本系统分为前后台，分为普通用户和管理员两种角色；

管理员角色包含以下功能：

管理员登录,用户管理,分类管理,奶茶信息管理,订单管理,新闻管理等功能。

用户角色包含以下功能： 用户登录,按分类查看,查看商品详情,加入购物车,修改个人信息,查看订单,提交留言,留言管理等功能。

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

JSP+CSS+JavaScript+java+servlet+mysql

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src/com/hr/dao/Basedao.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http://localhost:8080/ 登录 管理员账号/密码：admin/admin 用户账号/密码：user/123456
