Java实战宠物店在线交易平台的实现流程
作者：qq_1334611189
读万卷书不如行万里路，只学书上的理论是远远不够的，只有在实战中才能获得能力的提升，本篇文章手把手带你用java+Springboot+maven+Mysql+FreeMarker实现一个宠物在线交易系统,大家可以在过程中查缺补漏，提升水平
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。
