Basic implementation of jwt token in a application to authenticate user and to implement the level of access in a application.
Its easy to run the code first downlad and extract the code in eclipse and sts import it as existing meaven project and in vs code just open the folder update the meaven project build once befor running the project. secondly, crate the database for the project for me it was "springboot" (database name) or you can create your own and for more changes you can do that in application.properties.
