隨著社會的發(fā)展，社會的各行各業(yè)都在利用信息化時代的優(yōu)勢。計算機的優(yōu)勢和普及使得各種信息系統(tǒng)的開發(fā)成為必需。

社區(qū)疫情防控管理系統(tǒng)，主要的模塊包括用戶管理，在線交流信息，人員檢測信息，外來人員報備，防疫須知信息，公告信息，疫情用品信息，訂單信息，評價信息功能。系統(tǒng)中管理員主要是為了安全有效地存儲和管理各類信息，還可以對系統(tǒng)進行管理與更新維護等操作，并且對后臺有相應的操作權限。

?開發(fā)工具：idea (eclipse) 環(huán)境：jdk1.8 ?mysql

基于springboot mybatis 開發(fā)
