我们正在尝试使用 Oracle 和基于 Hibernate/JPA（非弹簧）的应用程序来设置 javers 2.2.2。

使用内部存储库和标准（非事务性）构建器时，我能够成功记录和检索审计对象。但是，当我在切换到带有 SQL 的事务生成器后进行保存时，我得到了下面的堆栈跟踪。如果重要的话，我们确实在做 Hibernate Access Hook。

任何帮助是极大的赞赏！

该错误表明您正在尝试提交HibernateProxy。在运行时，Hibernate 将您的域对象和集合包装在代理对象中，主要用于延迟加载。所以你的域对象变得有点脏。在提交 javers 之前，您必须解开它们。

Javers 为此提供了专用的钩子 - HibernateUnproxyObjectAccessHook：

TransactionalJaversBuilder
    .javers().withObjectAccessHook(new HibernateUnproxyObjectAccessHook()).build()

有关更多详细信息，请参见http://javers.org/documentation/spring-integration/#hibernate-unproxy-hook

尝试通过ObjectMapper解析为

    MyClass myClass = new MyClass();
    return new ObjectMapper().writeValueAsString(myClass);
