将休眠版本从3.3.1GA更新到3.6.10.Final

时发生此错误

我正在更新一个应用程序（JSP + spring 4.2 + hibernate + java 8），在其中我需要执行编辑和添加功能，并将结果存储到两个表中，例如PriceSchedule和PriceScheduleItem。两者之间的关系是多对一的。在我的父hbm文件中，我通过一对多（子类字段）启用了 cascade =“ all” 。

我正在从数据库获取数据，并在编辑记录时，如果我不更改（在JSP中）任何字段值，那么它将引发如下异常。

org.springframework.dao.DuplicateKeyException: a different object with the same identifier value was already associated with the session: [com.pstechnology.domain.PriceSchedule#124]; nested exception is org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.pstechnology.domain.PriceSchedule#124]

如果我更改任何字段值，则说明保存成功。

Am使用命令对象从JSP获取信息。有人可以指导我解决此错误。

仅供参考： 1）通过将其设置为VO对象，将休眠域对象发送到JSP。 2）我无法再更新休眠版本，公司maven repo没有最新的休眠版本，管理层也不想在这些上花费很多时间。

DuplicateKeyException Hibernate 3版本在saveorUpdate上更新
