As @Laf said, Lombok doesn't currently support this feature. However, you still can get rid of some duplicated code by extracting setters logic to the following higher-order function:

private void doSetTacLacStartUe(
        Integer oldValue,
        Integer newValue,
        Consumer<Integer> setter,
        BiConsumer<EventDocument, Integer> eventDocumentUpdater
) {
    if (Objects.equals(oldValue, newValue)) return;
    setter.accept(newValue);
    if (DocKind.ORIG == docKind)
        eventDocumentUpdater.accept((EventDocument) prepareDirtyDocument(), newValue);
}

And using it this way:

public void setTacLacStartUe1(Integer tacLacStartUe1) {
    doSetTacLacStartUe(getTacLacStartUe1(), tacLacStartUe1, it -> this.tacLacStartUe1 = it, EventDocument::setTacLacStartUe1);
}

Answer 2

Based on the current version's documentation (https://projectlombok.org/features/GetterSetter), it doesn't seem to include a way to specify custom checks for the setter (or getter). I fear you will have to manually code each and every setter.

The same applies for the experimental @Accessor feature.
