- 动手需求分析，希望巩固自己已经有的技术，并且如果在开发中遇到新技术，便于学习新技术。
- 本系统分2大部分，跟大众系统的功能差不多，一个是后台管理系统：商家管理后台登录用户，商家详细信息管理，商品的上架，下架，信息修改，查询所有商品的功能，统计商品的销售情况。另一个是前台的商品展示页面，包括购买者的注册，登录，购物车，商品展示，商品详细信息浏览等。
- 数据库和数据库表只能系统搭建好后慢慢分析了。
- 运用的工具和技术：eclipse4.3+tomcat7+mysql springMVC+mybatis+ajax+json+jQuery+easyui前端框架
一、系统框架搭建
- 建立CopyYSL工程：
- 配置spring-mvc.xml
