项目介绍

网上花店销售系统采用JSP+Servlet+JavaBean的MVC模式，将数据对象、业务逻辑以及用户界面分离。该系统分为用户和管理员两个角色。用户注册登录后可以浏览鲜花，浏览公告，购买鲜花，管理员登录后可以对系统进行管理和维护。

由于本程序规模不大，可供课程设计，毕业设计学习演示之用。

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 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

Servlet、JSP、JDBC、MySQL5.7、Tomcat8

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，然后运行；
3. 将项目中src/com/dao/DB.java配置文件中的数据库配置改为自己的配置;
4. 运行项目，在浏览器中输入地址；

前台地址：http://localhost:8080/flowerstore/
普通社员账号：zhangsan 密码：123456

后台地址：http://localhost:8080/flowerstore/manage/login.jsp
管理员账号：admin 密码：123456
