该项目为前后台项目,分为普通用户与管理员两种角色,前台普通用户登录,后台管理员登录;
管理员角色包含以下功能:
管理员登录,用户管理,鲜花类别管理,鲜花管理,订单管理并发货,留言管理,系统公告管理等功能。
用户角色包含以下功能:
用户首页,用户注册登录,查看鲜花详情,加入购物车,确认订单,查看我的订单,商城留言板,商城公告等功能。
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;
1. 后端:Spring+SpringMVC+Mybatis
2. 前端:JSP+jQuery+Ajax
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jdbc.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/ 登录
