java - How to get the name of the key while handling DataIntegrityViolationException?

Question

I'm using GenericExceptionHandling on the application level

@ControllerAdvice
public class GlobalExceptionHandler {

    // Handle the DataIntegrityViolationException
    @ExceptionHandler(DataIntegrityViolationException.class)
    public ResponseEntity<?> customDataIntegrityViolationException
                                (DataIntegrityViolationException exception) {

    String message = "This {key} is already exist";
    ErrorDetails errorDetals = new ErrorDetails(new Date(), message, exception.getCause().getMessage());
    return new ResponseEntity<Object>(errorDetals, HttpStatus.UNPROCESSABLE_ENTITY);
    }

}

I want to get the name of the key that's causing error. i.e. {key}. I googled but didn't get any answer that solve my problem. If anyone have done this kind of work please tell.
