项目介绍

基于Springboot + vue实现的校园周边美食探索及分享平台

本系统包含管理员、用户两个角色。

管理员：用户管理、美食鉴赏管理、好友管理、收藏管理、系统管理

用户：登录、注册、个人中心管理、美食鉴赏管理、好友管理、收藏管理、个人信息管理、美食鉴赏发布与管理

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；

技术栈

后端：SpringBoot+Mybaits

前端：Vue+elementui

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；
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;
4. 运行项目，在浏览器中输入地址：
前台地址：
http://localhost:8080/springboot35l3z/front/index.html
