篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用Springboot+MybatisPlus+Echarts+Mysql从0-1完成中国疫情地图可视化动态展示相关的知识,希望对你有一定的参考价值。
最近北京疫情也严重了起来,突然想到了这个动态的echarts全国疫情数据动态展示,做的不好仅供参考
前言:用到的技术栈:Springboot+MybatisPlus+Echarts+Mysql
1 创建数据库表和新增基本的数据
方便大家使用我直接导出了.直接运行即可

3 编写基本的模块代码
配置
spring:
datasource:
#mysql
driver-class-name: com.mysql.cj.jdbc.Driver
password: root
url: jdbc:mysql:///novc?serverTimezone=GMT&allowPublicKeyRetrieval=true&useSSL=false&characterEncoding=utf8
username: root
#web
web:
resources:
static-locations: classpath:/META-INF/resources/, classpath:/resources/, classpath:/static/, classpath:/public/, classpath:/templates/
index配置
4 静态页面(echarts写死数据)
推荐一个echarts网址:https://www.isqqw.com
我参考的是这个:https://www.isqqw.com/echartsdetail?id=23968
spring:
datasource:
#mysql
driver-class-name: com.mysql.cj.jdbc.Driver
password: root
url: jdbc:mysql:///novc?serverTimezone=GMT&allowPublicKeyRetrieval=true&useSSL=false&characterEncoding=utf8
username: root
#web
web:
resources:
static-locations: classpath:/META-INF/resources/, classpath:/resources/, classpath:/static/, classpath:/public/, classpath:/templates/

访问 http://localhost:8080 出现地图说明完成,接下来进行改动,数据动态从数据库获取
5 动态页面(数据从数据库查询进行展示)
