项目介绍

本项目分为前后台，分为管理员与普通用户两种角色，管理员登录后台，普通用户登录前台；

管理员角色包含以下功能：

管理员登录,订单管理,客户管理,类目管理等功能。

用户角色包含以下功能：
首页,商品分类,热销和新品,注册新用户,用户登录,查看个人中心,购买商品,查看购物车,提交订单,模拟支付成功,查看订单等功能。

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+jQuery+bootstrap+mysql+servlet

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/utils/DBUtil.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_cakeshop/ 登录 注：tomcat中配置项目路径必须为jsp_cakeshop，否则会有异常；
