This article will explain in detail how to implement the work management system in Java. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

There are two roles of foreground user and backend administrator:

Front desk user functions are: post part-time, post, view bulletin, personal center, complaints and so on.

Background administrator functions are: user management, part-time management, post management, chat management, advertising management, complaint management, collection management, system management and so on.

Running environment: jdk1.8, tomcat7.0\ 8.5, Eclipse, Mysql5.x.

Background role Management Controller:
