Hibernate不插入字段，这是复合FK的一部分

Question

我有一个hibernate实体，它有两个多对一关联和复合外键，每个外键有3个字段。两个键共用两个字段。有映射:

<class dynamic-insert='true' dynamic-update='true' entity-name='...' table='...'>
    <composite-id>
        <key-property name='FaultId' type='long' column='FAULT_ID'/>
        <key-property name='RowVersion' type='long' column='ROWVERSION'/>
    </composite-id>
    <many-to-one name='Pot' class='Pot'>
        <column name='SMELTER_ID' not-null='true'/>
        <column name='ROOM_ID' not-null='true'/>
        <column name='POT_ID' not-null='true'/>
    </many-to-one>
    <many-to-one name='Event' class='PotEventRef_NonGui'>
        <column name='EVENT_ID' not-null='true'/>
    </many-to-one>
    <many-to-one name='Shift' class='TimeShift' insert='false' update='false'>
        <column name='SMELTER_ID' not-null='true'/>
        <column name='ROOM_ID' not-null='true'/>
        <column name='TIMESHIFT' not-null='true'/>
    </many-to-one>
</class>

插入实体代码:

session.persist(entry.getName(), entry.getData());

where session - org.hibernate。Session, entry.getName() - String, entry.getData() - Map<String,>.

当我尝试插入该类的实体时，没有插入timshift字段。(Shift对象设置，所有值正确)。问题的根源是什么?

尝试将更新值更改为true &通过删除XML中的insert='false'

<many-to-one name='Shift' class='TimeShift' update='true'>
