How to throw an exception back in JSON in Spring Boot

Question

I have a Request Mapping -

  @RequestMapping(\"/fetchErrorMessages\")
  public @ResponseBody int fetchErrorMessages(@RequestParam(\"startTime\") String star         


        

Answer 1

you can create NotFoundException class with @ResponseStatus annotation like below:

@ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
public class NotFoundException extends RuntimeException {
   public NotFoundException() {
   }

   public NotFoundException(String message) {
    super(message);
   }

}
