目录一、项目简述二、效果图展示三、核心代码管理员controller控制层管理员角色controler控制层后台登录控制层订单模块controller控制层

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 + css + javascript + jquery + Ajax + layui+ maven等等。

二、效果图展示

三、核心代码

}

}

订单模块controller控制层
