P.P.S. 좋아, 나는 Javers Comparing Lists 다음의 코멘트를 발견했다.LEVENSHTEIN_DISTANCE는 목록을 비교하여 순서를 무시하지 않습니다.
JaVers리스트 비교 알고리즘에는 이동의 개념이 없다. 이동 후에는 언급 한 것처럼 ValueAdded와 ValueRemoved라는 두 가지 변경 사항이보고됩니다.
하지만 실제로 어떻게 목록이 변경되지 않았는지 어떻게 알 수 있습니까?
P. @Entities와 @Id를 ZasFish, ZasCatchZone 및 ZasCatchArea로 가져가도 여전히 Diff : 1. NewObject {globalId : 'my.javers.comparator.ZasFish/2'} 2. ObjectRemoved {globalId : 'my. javers.comparator.ZasFish/1 '}
사용자 지정 개체 목록을 비교하려고합니다. LEVENSHTEIN_DISTANCE를 설정하고 맞춤 비교자를 만들었습니다. 객체 간의 유일한 차이점은 목록에있는 값의 순서입니다. 나는 "변화 없음"을 기대하지만 ListChange를 얻었다. 그 결과와 예가 아래와 같습니다. 내가 도대체 뭘 잘못하고있는 겁니까?
많은 감사와 안부 안드레이
