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。
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
