Question

Newbie question... I\'m building my first Spring Boot restful service. My restful service design requires some data to be returned in the response header.

How do I

Unlike the other answer, don't use HttpServletResponse. You don't wanna be working with low-level Servlet APIs if you can avoid it. Return a ResponseEntity or HttpEntity.

HttpHeaders headers = new HttpHeaders();
headers.add("1", "uno");

return new ResponseEntity<>(headers, HttpStatus.OK);
