PPS 好的，我在评论之后创建了他的 Javers 比较列表
JaVers 列表比较算法中没有移动的概念。移动后将报告两个更改：ValueAdded 和 ValueRemoved，就像您提到的那样。
但是我怎么能认出这个列表实际上并没有改变呢？
PS 即使我得到 @Entities 和 @Id 到 ZasFish、ZasCatchZone 和 ZasCatchArea 我仍然得到 Diff: 1. NewObject{globalId:'my.javers.comparator.ZasFish/2'} 2. ObjectRemoved{globalId:'my.javers.比较器.ZasFish/1'}
我正在尝试比较自定义对象的列表。我设置了 LEVENSHTEIN_DISTANCE 并创建了自定义比较器。对象之间的唯一区别是列表中值的顺序。我希望“没有变化”，但我得到了 ListChange。结果和示例如下。我究竟做错了什么？
非常感谢和问候， 安德烈
