基于java SSM框架的游戏商城系统

今天给大家介绍一个使用java SSM框架的游戏商城系统，案例比较典型，更换一些内容可以作为其他商品的商城系统使用，话不多说上截图：

技术描述
开发工具： idea

数据库： mysql

Jar包仓库： 普通jar包

前端框架：jquery/bootstrap

后端框架： sping+springmvc+mybatis

资料说明
基于SSM实现的游戏商城系统,采用JSP渲染页面，后端整体采用Spring SpringMVC Mybaits框架实现。商城首页提供一系列热门游戏的展示，例如一些热门单机游戏，使命召唤等。用户浏览之后可以添加到购物车。用户注册登录系统后，方可进行结算等其他购物车操作。提供付款，结算。订单等其他操作。在导航栏中可以进入后台界面，后台提供了，用户管理，订单管理，商品管理，类目管理等功能。
