基于javaweb的SpringBoot超市订单管理系统(java+springboot+jsp+mybatis+maven+mysql)

运行环境

Java≥8、MySQL≥5.7

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb的SpringBoot超市订单管理系统(java+springboot+jsp+mybatis+maven+mysql)

项目介绍

该超市订单管理毕业设计基于jdk8版本开发，在部署时需要使用jdk8以上的版本。使用了目前流行的框架组合springboot+mybatis的框架技术， 实现了供应商管理对供应商实现增删改查、订单管理对超市订单实现增删改查、用户管理等功能，适用于小型超市的使用，通过学习该超市订单管理，对于springboot+mybatis框架的组合能够有更深层次的理解。

环境需要

1.运行环境：最好是java jdk 1.8，我们在这个平台上运行的。其他版本理论上也可以。
2.IDE环境：IDEA，Eclipse,Myeclipse都可以。推荐IDEA;
3.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
4.数据库：MySql 5.7版本；

技术栈

1. 后端：springboot MyBatis

2. 前端：JSP+css+javascript

使用说明
运行成功后，访问http://localhost:8080/ 到登录页面
