Project Introduction
The online learning system implemented by SpringBoot+Spring+Mybatis+Thyleaf has a total of 2 identities.
After the administrator logs in to the system, he can manage all user information, manage role information, add and modify courseware information, manage student learning and training batches, and manage results import
. Training records, check your own grades
The SpringBoot framework is used to implement the thymeleaf database layer for the front-end template, and the mybatis framework annotation mode is used
The upload folder is placed in the root directory of the D drive!
