手机java平台_java微服务开源框架

源码获取：俺的博客首页 “资源” 里下载！ 

项目介绍

基于SpringBoot手机商城 有前台和后台
用户可以登录注册 收藏商品 购物车 结算商品 收货地址管理等
管理员则可以对用户，商品，订单进行管理操作

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 5.7/8.0版本均可；
5.是否Maven项目：是；

技术栈

后端：SpringBoot(Spring+SpringMVC+Mybatis)

前端: HTML+Layui+thymeleaf

使用说明

项目运行：
1. 使用Navicat或者其它工具，在mysql中创建对应sql文件名称的数据库，并导入项目的sql文件；
2. 使用IDEA/Eclipse/MyEclipse导入项目，导入成功后请执行maven clean;maven install命令，然后运行；
3. 将项目中application.yml配置文件中的数据库配置改为自己的配置;
