我试图手动添加＆＃34; org.hibernate.AnnotationException＆＃34;到白名单。我试图在我的州类中实现serializationWhitelist接口。
假设我的状态类是Person类型，并且在其中定义了Address类型。每当我试图将状态从保险库中取出时，我都会收到此错误。或＃34; org.hibernate.MappingException＆＃34;。此外，当我的状态实现QueryableState时，我甚至无法持久保存数据。并得到以下错误

答案 0 :(得分：0)
由于您的代码存在潜在问题，您的流程会引发各种异常。 Corda然后尝试将这些异常序列化，以通过RPC框架将它们发送回RPC客户端。由于这些类型不是通过RPC发送的白名单，因此在尝试时会出现Kryo异常。
换句话说，这些异常只是（基础代码throwijng AnnotationException或MappingException）的症状，而不是根本原因。
您是否可以发布显示Person状态定义的代码以及您尝试从流中的Vault中检索它的方式？
