This article mainly introduces Java how to achieve the rights management system, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Springboot+mybatis uses a rights management system implemented by aspect-oriented programming (AOP). A total of five modules, role management, menu management, laboratory management, student management, administrator management.

Role management is divided into a super administrator, editing permissions. Menu management displays links and edits for each management. Laboratory management has excel import, the total number of people signed in. Student management has excel import. Additions, deletions, modifications and queries can be realized in each part.

Background role Management Controller:
