Question

这个错误不允许我访问jsondoc，我已经尝试过这里提供的一些解决方案，但我仍然遇到同样的问题。

我希望我能够清楚地知道我希望你帮助我。

我留下了错误以及错误中提到的其中一个类。

      Caused by: org.hibernate.loader.MultipleBagFetchException: cannot  
      simultaneously fetch multiple bags: 
      [com.credix.sib.canales.applicant.Applicant.phoneApplicant, 
      com.credix.sib.canales.applicant.Applicant.addressApplicant]

添加了错误

中显示的其中一个类

Answer 1

如消息所示：您POST。

要解决问题，您可以：

将用于cannot simultaneously fetch multiple bags和phoneApplicant的集合类型从addressApplicant更改为List。此解决方案将导致集合无订单且无重复。如果您坚持订购带有可能重复的订单，请使用下面描述的第二个选项。
为两个列表使用注释Set提供订单列。
