I need to add login and register controllers for accessing other REST controllers in spring.
There is no connection to database yet -- It's not required to read/write to database anything.
For managing users Login and Register should only use global Kotlin objects, I'll make database connections by myself.
I have only three small controllers, it's small mocked program.
Answer to this questions in your proposal, otherwise I will consider it as spam:
1. What is JWT?
2. What is file extension for kotlin file?
3. How many controllers do I currently have in project?
4. Do you need to work with Hibernate in this job?
