Hibernate实体版本没有增加，但数据库版本字段是

Question

我不知道如何处理以下事项：

1. 我在客户端创建一个实体，将其发送到服务器，合并并调用saveOrUpdate。合并后的实体将返回给客户端;
2. 然后在客户端上修改实体，发送到服务器并再次调用saveOrUpdate。该方法退出但实体未更新其version号码并将其发送到客户端。现在，实体的版本号与数据库不同步。 数据库中的实体version字段已正确更新;
3. 该实体将从其父集合中删除，但由于equals()方法使用version字段，因此它失败并且不会删除该实体。或者我在再次更新实体时获得OptimisticLockException。

这是Hibernate的正常行为吗？

1. 如果没有，可能是什么造成的呢？
2. 如果是，那么我必须手动更新每个修改过的实体的版本字段，然后再将其返回给客户端吗？

服务类

public List<HtDayEntry> deleteHtDayEntry(String clientVersion,
        @Lazy HtDayEntry htDayEntryToDelete, List<HtDayEntry> modifiedHtDayEntries)
        throws ClientServerVersionMismatchException {
    compareClientServerVersion(clientVersion);
    htDayEntryToDelete = (HtDayEntry) htDayEntryDao.merge(htDayEntryToDelete);
    // START: remove from the other side of the relationships
    HtDay htDay = htDayEntryToDelete.getHtDay();
    htDay.getHtDayEntries().remove(htDayEntryToDelete);
    HtDayEntryType htDayEntryType = htDayEntryToDelete.getHtDayEntryType();
    htDayEntryType.getHtDayEntries().remove(htDayEntryToDelete);
    for (HtNote htNote : htDayEntryToDelete.getHtNotes()) {
        htNote.setHtDayEntry(null);
    }
    // END: remove from the other side of the relationships
    htDayEntryDao.delete(htDayEntryToDelete);
    if (isHtDayEmpty(htDay)) {
        htDayDao.delete(htDay);
    }
    if (modifiedHtDayEntries != null) {
        HtDayEntry modifiedHtDayEntry;
        ListIterator iterator = modifiedHtDayEntries.listIterator();
        while(iterator.hasNext()){
            modifiedHtDayEntry = (HtDayEntry) iterator.next();
            modifiedHtDayEntry = (HtDayEntry) htDayEntryDao.merge(modifiedHtDayEntry);
            htDayEntryDao.saveOrUpdate(modifiedHtDayEntry);
            // START: must manually update the version field, I have no idea why
            modifiedHtDayEntry.setVersion(modifiedHtDayEntry.getVersion() + 1);
            iterator.set(modifiedHtDayEntry); // Update the modifiedHtDayEntry in the iterator so that the new version number can be returned
            // END: must manually update the version field, I have no idea why
        }
    }
    return modifiedHtDayEntries;
}

HtDayEntryDao

public void saveOrUpdate(Object object) throws HibernateException {
    getSession().saveOrUpdate(object);
}

实体（超类中的方法）

private long version;

@Version
@Column(name = "version")
public Long getVersion() {
    return version;
}

public void setVersion(Long version) {
    this.version = version;
}
