基于SpringBoot+Vue的前后端分离练习项目_springboot练习项目

1、项目介绍

这是一款基于SpringBoot+Vue的前后端分离的项目，麻雀虽小，五脏俱全，值得拥有！

全部源码放到文章最后

页面展示：

• 用户主页
  
• 管理员后台界面
  

2、技术选型

• 后端
  SpringBoot
  Hutool工具类库（*超好用）
  Redis缓存 （缓解多次刷新数据库压力）
  Lombok（减少写get、set等方法）
  Mysql5.7+
  Mybatis
  ​ Mybatis-Plus

• 前端
  ​ Vue2
  ​ Vue-Router
  ​ VueX
  ​ ElementUI
  ​ Apache ECharts (可视化图标插件)
  ​ Axios
  ​ 高德地图Api

3、数据库设计

Mysql5.7+ 、Nvaicat（MySQL可视化工具）

字符集
utf8mb4
排序规则
utf8mb4_unicode_ci
