项目简单，适合大学生参考

分类专栏还有其它的可视化博客哦！

专栏地址：https://blog.csdn.net/qq_55906442/category_11906804.html?spm=1001.2014.3001.5482

成果展示：

 一、数据源

1）可以使用自己的MySQL数据库；

2）使用我提供的数据。（要数据私信/留言——>留下邮箱即可）

二、所需工具

MySQL、IDEA、jdk1.8、Maven等等，总之编写工具要准备好，环境要搭建好

三、项目框架搭建

参考我博客的项目框架搭建，从3.1看到4.3即可springboot+mybatis+echarts +mysql制作数据可视化大屏_spring + 可视化大屏_一个人的牛牛的博客-CSDN博客

四、代码编写

代码简单，后端代码都写在一起了，没有区分controller等等，前端也是一样，没有单独写js等等。
