java - @PreUpdate 上的 Stackoverflow

每当我尝试在实体上使用 @PreUpdate 注释时，都会收到 stackoverflow 异常，该实体使用嵌入式可审计实体和 @EntityListeners。

在我的实体中，我尝试通过服务获取用户数据，以便更新实体上的 CreateBy/LastUpdateBy 字段。我不能简单地将字符串放入其中，我需要对用户本身的引用。

我已经尝试过将实体管理器注入(inject) AuditListener 并手动刷新它的方法，但它无法正常工作。另外，我尝试在 spring 上下文中传递用户数据而不是使用服务，但由于它保留静态值，所以它对我没有用处。我需要以某种方式获取 AuditListener 中的 User 实体，而不进入无限循环。

有什么想法吗？

这是堆栈跟踪:

最佳答案

默认情况下，所有事务都是读/写，并且由于您使用@PreUpdate，由于读/写事务上的FlushMode，因此所有事务都将始终触发它。在您的情况下，如果您想在只获取需要为事务指定的数据(至少为readOnly)的情况下绕过@PreUpdate，这将在FlushMode.NEVER中创建hiberbate session ，因此@PreUpdate将不会被触发。为了更加安全，以防您的事务嵌入到 pervios 事务中，以便它将继承其属性，您可以使用 Propagation.REQUIRES_NEW 这将暂停以前的事务执行，但要小心它，因为这可能会导致大型应用程序中的性能问题
