我是 R3 Corda 新手。我一直陷入这个问题。我花了几个小时试图解决这个问题。我在运行节点时遇到 Hibernate AnnotationException 。这是我的架构声明文件 NewInspirationSchema.java。

我能够毫无异常(exception)地进行构建，但是当我尝试运行节点时，我会在节点的命令提示符上记录以下错误。我一直在尝试互联网上的所有解决方案，但没有一个与 Corda 相关。所有这些都仅与 Hibernate 相关。我觉得我缺少 Corda 的任何特殊注释，或者我对架构的思考方式是错误的。请帮助我。

最佳答案
您需要在构造函数中包含您引用的所有架构实体:
super(NewIndicationSchema.class, 1, ImmutableList.of(Indication.class, Insure.class));
关于java - AnnotationException : @OneToOne or @ManyToOne on MySchema$Parent. propertyX 引用未知实体:MySchema$Child，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51830398/
