项目编号：BS-XX-038
本系统基于springboot实现开发，主要实现国内各省的疫情数据管理及实时统计，特点是利用图形报表实现展示各省确诊人数、疑似人数、隔离人数、治愈人数，利用不同的数据展示方式来进行数据的体现，并带有后台管理功能。
\
Java: jdk1.8
Mysql: mysql5.7
Tomcat: tomcat8.5.31
开发工具：IDEA或eclipse
前台数据统计：
\
后台登陆
\
录入各省分数据：点提交后换一批省份，直接所有的省份数据录入完毕
数据查询：查询今日各省数据
\
\
\
图表展示：
\
用户录入：
\
用户编辑：

本系统很有特点，数据统计准确，比较适合做毕业设计或课程设计使用。
