使用具有复合键的Hibernate条件对象时出现问题
注：由于提供的评论，我已更改了提供的详细信息。新的技术细节实际上是我目前正在尝试运行的代码 我现在有一个奇怪的问题，就是我的一对一/多对一双向关系 在父表中，我有一个long，它是标识符，子表除了另一个字段外，还有该列，该字段构成了它的复合键 在我查询的示例数据中，子表中有1条父记录和3条相关记录。目前，当我使用criteria对象查询表时，我会返回3条父（copolicPointer）记录，其中2条没有链接关联的子（CoTransactionSummary）表，然后是正确填充的第三条记录。我本以为只会得到一个结果，这就是为什么我感到困惑。你知道为什么会发生这种事吗 我在下面提供了更多的技术数据 Parent Table (CoPolicyPointer) Column Data Type SystemAssignId String (Primary Key) PolicyPrefixCd String PolicyId String PolicySeqNo int Child Table (CoTransaction Summary) Column Data Type SystemAssignId String (composite key) TransSeqId int (composite key) TransType varchar(4) 父类看起来像：使用具有复合键的Hibernate条件对象时出现问题,hibernate,jpa,Hibernate,Jpa,注：由于提供的评论，我已更改了提供的详细信息。新的技术细节实际上是我目前正在尝试运行的代码 我现在有一个奇怪的问题，就是我的一对一/多对一双向关系 在父表中，我有一个long，它是标识符，子表除了另一个字段外，还有该列，该字段构成了它的复合键 在我查询的示例数据中，子表中有1条父记录和3条相关记录。目前，当我使用criteria对象查询表时，我会返回3条父（copolicPointer）记录，其中2条没有链接关联的子（CoTransactionSummary）表，然后是正确填充的第三条记录。我本
