using java generics, I'll give you an example.
getter,setter I won't write about this 

  
 use @ ControllerAdvice and ResponseBodyAdvice. The Controller layer doesn't need to care at all about how to spell your json. It is all handled in advice. 
 or use aop. Block all controller or part of controller. It is handled in aop. 
 both of these are better than wrapping the return value directly in the business code or the controller layer, and you don't need to change every method when refactoring.
