Repository , I am using Spring and REST , I need to return all entities that have another entity, I would get them by id, and I need to feed a call ajax with it, then it would need a json array. If anyone can help, I would be very grateful.
I found the solution, I create methods with specific names like this:
List<Answer> findByQuestionIdAndDeadIsFalse(String questionId);
I created inside Repository and called it, making a dependency injection where I need it, in my case not Controller .
