休眠审核字段更改的日志 [英] Hibernate audit log of fields' change

问题描述

如何将实体的更改记录到日志文件中?考虑我有这样的 Person .

  import org.hibernate.envers.Audited;导入javax.persistence.Entity;导入javax.persistence.Id;导入javax.persistence.GeneratedValue;导入javax.persistence.Column;@实体@审核公共班级的人{@ID@GeneratedValue私人int ID；私有字符串名称；私有字符串姓；//在此处添加getter，setter，构造函数，equals和hashCode} 

以及更改现有 Person

的代码

  Person p1 = new Person("name-1"，"surname-1");personRepository.save(p1);人p2 = personRepository.findOne(1L);p2.setName("new-name");personRepository.save(p2); 

我怎么有

• 旧实体
• 新实体
• 字段列表已更改(类似 Diffable 的结果

在我的日志文件中?我知道 envars 可以将更改存储在db中，并让我以后使用提取它们AuditReader ，但我想将更改存储在Json文件中，以将其发送给第三方应用程序(例如Elastic).

解决方案

您可以通过实现 org.hibernate.EmptyInterceptor 来编写自定义拦截器.它具有使用实体的旧快照和新快照更新/插入/删除的回调.

How can I log the changes of the entity into log files? Consider I have Person like this.

import org.hibernate.envers.Audited;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.Column;

@Entity
@Audited
public class Person {
    @Id
    @GeneratedValue
    private int id;

    private String name;
    private String surname;
// add getters, setters, constructors, equals and hashCode here
}

and a code of changing existing Person

Person p1 = new Person("name-1", "surname-1");
personRepository.save(p1);
Person p2 = personRepository.findOne(1L);
p2.setName("new-name");
personRepository.save(p2);

How can I have

• old entity
• new entity
• list of fields changed (some thing like Diffable's result)

In my log file? I know that envars can store changes in db and let me extract them later with AuditReader but I like to store changes in Json file to send them to third party applications (like Elastic).

解决方案

You could write a custom interceptor by implementing org.hibernate.EmptyInterceptor. This has callbacks to update/insert/delete with old and new snapshots of entities.
