Is there any annotation to let us get another value if original value is null?

@Getter
@NoArgsConstructor
@AllArgsConstructor
@ToString
public class SomeDto extends BaseDto {

    private BigDecimal a;

    @GetOrAlternative(alternative = "a")
    private BigDecimal b;

For example, I want to get value a if b is null on above code. I want to use that like dto.getBOrAlternative(). Is that possible? If that is not possible, how can I implement that?

I tried to make custom annotation and processor following this: https://www.happykoo.net/@happykoo/posts/256 However, it didn't work. I think it is because that is not a field level.

You're saying there's no implementation of what I want yet, right? – 김효성 Feb 13 '23 at 08:42
