java 网上商城实现 java web网上商城设计与开发

基于javaweb+springboot的网上商城系统设计和实现(java+Springboot+ssm+mysql+jsp+maven)

一、项目简述
本系统主要实现的功能有： OnlineMall项目是一套电商系统，包括OnlineMall商城系 统及OnlineMall商城后台管理^统，基于Spring Boot 2.X 及相关技术栈开发。前台商城系统包含首页门户、商品分 类、新品上线、首页轮播、商品推荐、商品搜索、商品展 示、购物车、订单结算、订单流程、个人订单管理、会员 中心、帮助中心等模块。后台管理系统包含数据面板、轮 播图管理、商品管理、订单管理、会员管理、分类管理、 设置等模块。

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： Springboot+ SpringMVC + MyBatis + ThymeLeaf + JavaScript + JQuery + Ajax + maven等等
