Java實(shí)戰(zhàn)之小米交易商城系統(tǒng)的實(shí)現(xiàn)

 更新時(shí)間：2022年04月06日 14:44:22   作者：qq_1334611189  
這篇文章將利用Java實(shí)現(xiàn)小米交易商城系統(tǒng)，文中采用的技術(shù)有：JSP?、Spring、SpringMVC、MyBatis等，感興趣的小伙伴可以跟隨小編一起學(xué)習(xí)一下

一、項(xiàng)目簡(jiǎn)述

環(huán)境配置：

Jdk1.8 + Tomcat8.5 + mysql + Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）

項(xiàng)目技術(shù)：

JSP +Spring + SpringMVC + MyBatis + html+ css + JavaScript + JQuery + Ajax + layui+ maven等等。

二、效果圖

三、核心代碼

用戶購(gòu)物車控制層
