Save, find, delete everything works. My idea was that i can just find user, edit him and save but there must be better idea.

Answer 1

It sounds like the login, password, and email fields are null when you get to the userRepository.save() call. Could you show the actual HTTP request you're sending from Postman?

Just curious, did you consider using spring-data-rest and having it automagically create the REST interface? You wouldn't need to write your own controller then.
