我有以下两个实体：
1- 播放列表：
@OneToMany(fetch = FetchType.EAGER, mappedBy = "playlist", orphanRemoval = true, cascade = CascadeType.ALL)
@OrderBy("adOrder")
private Set<PlaylistadMap> PlaylistadMaps = new HashSet<PlaylistadMap>(0);
-
级联类型.ALL：保存或更新播放列表实体时需要在 PlaylistadMap 集合上进行保存和更新。
-
孤儿移除 = true：删除播放列表实体时需要，PlaylistadMap引用也应该删除。
2- 播放列表地图：
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "fk_playlist", referencedColumnName = "pkid", nullable = false)
private Playlist playlist;
使用删除播放列表时getCurrentSession().delete();我收到以下异常：
org.springframework.dao.InvalidDataAccessApiUsageException: deleted object would be re-saved by cascade (remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]; nested exception is org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [com.xeno.advertisingsuite.web.domain.PlaylistadMap#6]

请告知如何解决此异常。
解决方案是严格执行异常消息告诉您的操作：
引起原因：org.hibernate.ObjectDeletedException：已删除的对象将通过级联重新保存（从关联中删除已删除的对象)
从它所在的关联（集合、列表或映射）中删除已删除的对象。特别是，我怀疑，PlayList.PlaylistadMaps。仅仅删除对象是不够的，您必须将其从引用它的任何级联集合中删除。
事实上，既然你的收藏已经orphanRemoval = true，您不需要显式删除它。您只需将其从集合中删除即可。
