这篇文章将为大家详细讲解有关Java如何实现宠物店在线交易平台，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
该系统分为前台和后台，前台可以自主注册，后台管理员角色，除基础脚手架外，实现的功能有：
后台管理员功能有：
商品分类管理、商品管理、套餐管理、新闻分类管理、新闻管理、常见问题、关于我们、团队管理、订单查看和前台用户查看等功能。
前台用户功能有：注册登录、查看商品、购物车、支付订单、评价、照片库、新闻列表、个人中心、购买套餐等功能。
运行环境：windows/Linux均可、jdk1.8、mysql5.7、maven3.5\maven3.6、idea/eclipse均可。
