cost的配置
<set name="orderses" inverse="true" cascade="save-update,persist" >
            <key>
                <column name="COSTID" precision="22" scale="0" />
            </key>
            <one-to-many class="com.youkan.order.model.Orders" />
</set>oredr的配置
 <many-to-one name="cost" class="com.youkan.order.model.Cost" fetch="select" >
            <column name="COSTID" precision="22" scale="0" />
        </many-to-one>hibernate异常

Answer 1

保存cost对象的时候还有游离的对象没有保存，这样hibernate没法flush刷新发出SQL。检查下orders对象。是否是新new的没有保存。

Answer 2
