Spring MongoDB驱动程序不支持Java域对象的层次结构

当尝试在层次结构中为mongodb集合设计java域对象时，会引发异常。根据JSON表示，这应该是允许的，但这里不支持。有人知道原因吗？它是spring mongo驱动程序中的一个bug吗

@Document
public class SomeReason{
  private SomeReason reason;
  private List<String> options;
  // getter & setter
}

支持层次结构。您得到的异常是什么？您的代码没有问题，实体应该按照预期在MongoDB中进行映射。您得到的异常记录为
