I am trying to autowire my jpa repository. However, it is getting autowired as null. I was following a tutorial! that said the interface that extends CrudRepository will be created in runtime by spring for me. Of course, I can write all the implemented methods from scratch. Still, I want to know if the tutorials spring base configuration is possible for me.
I have tried using the @EnableJPARepositories annotation, and it did not work.

user.setRole(Role.USER);
repository.save(user);
