Java 仿天猫服装商城系统的实现流程
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+SSM+jsp+mysql+maven实现一个仿天猫服装商城系统,大家可以在过程中查缺补漏，提升水平
一、项目简述
功能：网上商城系统，前台+后台管理，用户注册，登录, 上哦展示，分组展示，搜索，收货地址管理，购物车管 理，添加，购买，个人信息修改。订单查询等等，后台商 品管理，分类管理，库存管理，订单管理，用户管理，信 息、修改等等。
二、项目运行
环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)
项目技术： JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。
