将 Corda 节点迁移到 Corda 4.3 时休眠

Question

升级到 Corda Open Source 4.3 时，我在节点启动时遇到了这个错误。这是 Corda 要求的使用 Hibernate 5.4.3。

[ERROR] 2019-12-18T16:17:25,820Z [main] internal.NodeStartupLogging. - Exception during node startup: Could not create Hibernate configuration:

Answer 1

这是由 Hibernate 中的一个已知问题引起的，如下所述：https://hibernate.atlassian.net/browse/HHH-13060

按照 cmets 中的建议，设置实体名称注释可以解决异常。
