Hibernate envers - 如何只存储更新的值 [英] Hibernate envers - How to store only updated values

问题描述

我正在使用Hibernate Envers进行审计。更新后和插入后工作正常。

我有一个需求，只需要审计审计表中更新的列（例如employee_aud）。
默认情况下，envers会将整个持久化实体插入到审计表中。

我只需要插入更新的值。

有没有可能做到这一点？

预先致谢。

干杯！

解决方案

当您使用 @Audited 注解实体时，您正在控制Envers在发生更改时应检查哪些属性。然后这些属性在旧状态和新状态之间进行比较，如果有任何不同，Envers将为所有审计属性编写一个新的审计记录，其中包含新的状态值。

其他单词，Envers不会只编写一个新的审计行，只有您为了审计而修改的属性。如果任何审计属性发生变化，它将编写一个新的审计行。

I am using Hibernate Envers for my Auditing. Post-update and post-insert works fine.

I have a requirement where I need to audit only the updated columns in the audit table (e.g. employee_aud). By default envers will insert the entire persisted entity in to the audit table.

I need to insert values only which are updated.

Is there any possibility to do this ?

Thanks in advance.

Cheers !

解决方案

When you annotate an entity with @Audited, you're controlling which properties Envers should inspect when changes occur. Those properties are then compared between the old and new state and if any differ, Envers will write a new audit record with the new state values for all audited properties.

In other words, Envers won't write a new audit row with only the modified properties you have toggled for audit. It will write a new audit row with all audited properties if any of them change.
