CollectionKey

public CollectionKey(CollectionPersister persister,
                     Serializable key)

CollectionKey

@Deprecated
public CollectionKey(CollectionPersister persister,
                     Serializable key,
                     EntityMode em)

已过时。

Use CollectionKey(CollectionPersister, Serializable)

The EntityMode parameter is now ignored. Use the other constructor.
