期望的结果

我想通过Set执行与AfpProcessDetail相关的一对多更新-AfpProcessSummaryDetail。当我尝试替换更新的设置值时，它会尝试将主键更新为null。如果我不替换更新，请不要进行更新。如果我设置了级联，则会给出错误 - 具有相同标识符值的不同对象已与会话关联：

  

[com.aurionpro.convertor.dto.AfpProcessSummaryDetail＃15a236f fc961];   嵌套异常是org.hibernate.NonUniqueObjectException：a   具有相同标识符值的不同对象已经关联   与会议。

请建议
