基于javaweb+mysql的JSP+Servlet在线酒类商城系统(java+jsp+bootstrap+servlet+mysql)
项目介绍
本项目为前后台项目，分为普通用户与管理员两种角色，普通用户登录前台，管理员登录后台；
管理员角色包含以下功能：
管理员登录,会员管理,管理员管理,资讯管理,图片广告管理,商品类别管理,品牌管理,商品管理,库存管理,订单管理,留言管理等功能。
用户角色包含以下功能： 用户首页,登录和注册,收藏商品,查看商品,加入购物车,新增收货地址,提交订单,查看我的订单,资讯查看,留言板等功能。
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+jquery+bootstrap+servlet+mysql
使用说明
- 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/util/SimpleDataSource.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localhost:8080/jsp_jiu_buy_online 登录 注：Tomcat中配置项目路径必须为jsp_jiu_buy_online，否则会报异常； 管理员账号/密码：admin/admin 用户账号/密码： user/123456
