2022-04-06 14:39:23 作者：qq_1334611189

这篇文章将利用Java实现小米交易商城系统，文中采用的技术有：JSP 、Spring、SpringMVC、MyBatis等，感兴趣的小伙伴可以跟随小编一起学习一下

一、项目简述

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。

二、效果图

三、核心代码
