One , Project brief introduction

This project is based on java development language , use SSM frame +MYSQL The campus epidemic management system developed by database , The system contains super administrators , System administrator 、 Student role , Function as follows ：

Super administrator ： Administrator management ; Student management ; Risk area management ; Itinerary management ; Health management ; Leave management 、 Epidemic notification ; Personal information modification 、 Change Password ;

System administrator ： The function is basically the same as that of super administrator , Only one administrator is missing ;

Student ： Home page chart statistics （ Histogram 、 The pie chart ）; Travel Report （ You can upload travel code and health code ）; Health Report （ Upload accounting test report ）; Leave management ; Epidemic notification ; Personal information modification 、 Change Password ;

The system interface is beautiful , It's very versatile , Used ssm、jquery、ajax、layui、echart Etc. technology stack , Suitable for graduation design 、 curriculum design .

Two , Introduction to the environment

Language environment ：Java:  jdk1.8

database ：Mysql: mysql5.7

application server ：Tomcat:  tomcat8.5.31

development tool ：IDEA or eclipse

Background development technology ：SSM frame +SpringTask Timing task

Front end development technology ：Layui+Jquery+AjAX+Echart
