前言:
目前全国的疫情防控整体上还是比较严峻的,国家主导的以人为本的动态清零政策,有效的遏制了疫情病毒的传播,但病毒的不断变异大大增加了防控的难度。而居民所处的社区管控一直是疫情防控的一线,社区管控的力度直接决定着全国整个疫情防控的成败。国家对于疫情的防控可以通过信息化和大数据对人的行踪进行有效的流调,通过信息化技术的应用大大降低了整体疫情防控的力度和患者排查的难度,但是处于一线的社区防控工作,在信息化的建设和应用上还是相对比较空白的,目前好多社区还是通过保安人工记录和统计社区人员的流动及相关信息,在此背景下,希望能够利用信息化技术,为社区防控开发一套管理系统,能帮助社区人员更好的管理社区居民疫情情况、进入情况,能够方便的实现对社区内各小区的人员情况有着更好的管理。本文就基于Springboot框架开发和实现一个应用于社区居民疫情防控管理系统的相关问题进行分析和研究。
一,项目简介
?本次开发设计的社区疫情管理系统,主要为一线的社区人员更好的管理辖区内人员疫情风险信息提供信息化的管理手段。本系统基于Springboot+Vue开发实现了一个前后端分离的信息化管理系统。系统功能完整,界面简洁大方。系统用户主要分为居民用户和管理员用户,居民注册登陆后主要可以在线提交自己的体温信息、外出信息、行程信息等,管理员用户主要管理和查看这些基础的信息数据。
? ? 特色:
1.系统利用定时任务每天自动爬取百度的疫情统计数据并更新到本地的数据库表中,在本系统中可以查看国内的最新疫情数据。
2.使用SpringSecutiry权限管理框架来管理用户的权限身份
3.使用前后端分离开发模式,将前端和后台有效的分离,通过Axios向后台代理转发请求接口
4.使用Jsoup爬虫来爬取百度的实时疫情数据,并进行解析,将解析的数据保存到mysql数据库中
二,环境介绍
语言环境:Java:? jdk1.8
数据库:Mysql: mysql5.7
应用服务器:Tomcat:? tomcat8.5.31
开发工具:IDEA或eclipse
后台开发技术:Springboot+Mybatis-Plus+SpringSecutiry+定时任务Quartz
前端开发技术:Vue+ElementUI+Axios
三,系统展示
下面展示一下社区疫情防控系统:

五,项目总结
经过几个月的努力与坚持,社区疫情防控管理系统终于完成了,关于社区防控的相关功能实现均按照初期的需求分析来进行并实现,整个开发过程从明确用户需求,到开发工具选择,比如选择什么框架,前后端是否要分离,再到具体的系统总体设计,做出总体设计说明书,再将总体设计细化为概要设计,以及后期的编码实现和内外部测试,最通过了系统的功能性测试。
