有条件的Envers审计 [英] Conditional Envers Auditing

问题描述

我有一个要求，只需在状态字段的更改上审核记录。我遵循文档章节教程15.8。有条件审计。

第1步：关闭自动Envers事件监听器注册。我有以下内容：

 < prop key =hibernate.listeners.envers.autoRegister> false< / prop> 
  

第二步：为适当的事件侦听器创建子类。

  public class DeleteEnversListener extends EnversPostDeleteEventListenerImpl {
 private static final long serialVersionUID = 5906427978349712224L; 
 private static Log log = LogFactory.getLog（DeleteEnversListener.class）; 
 
 public DeleteEnversListener（AuditConfiguration enversConfiguration）{
 super（enversConfiguration）; 
} 
 
 @Override 
 public void onPostDelete（PostDeleteEvent event）{
 log.info（!!! just logging entity !!+ event.getEntity（ ））; 
 super.onPostDelete（event）; 
 
 
 $ / code> 

类似地，我有

• InsertEnversListener


• UpdateEnversListener


• DeleteEnversListener
• CollectionRecreateEnversListener


• PreCollectionRemoveEnversListener


• PreCollectionUpdateEnversListener





步骤3：创建自己的 org.hibernate.integrator.spi.Integrator

  public class CustomEnversIntegrator extends EnversIntegrator {
 
 private static Log log = LogFactory.getLog（CustomEnversIntegrator.class）; 
 $ b @Override 
 public void integrate（配置配置，
 SessionFactoryImplementor sessionFactory，
 SessionFactoryServiceRegistry serviceRegistry）{
 
 super.integrate（configuration， sessionFactory，serviceRegistry）; 
 final AuditConfiguration enversConfiguration = AuditConfiguration.getFor（configuration，serviceRegistry.getService（ClassLoaderService.class））; 
 EventListenerRegistry listenerRegistry = serviceRegistry.getService（EventListenerRegistry.class）; 
 
 System.out.println（注册事件监听器）; 
 if（enversConfiguration.getEntCfg（）。hasAuditedEntities（））{
 listenerRegistry.appendListeners（EventType.POST_INSERT，new InsertEnversListener（enversConfiguration））; 
 listenerRegistry.appendListeners（EventType.POST_UPDATE，new UpdateEnversListener（enversConfiguration））; 
 listenerRegistry.appendListeners（EventType.POST_DELETE，new DeleteEnversListener（enversConfiguration））; 
 listenerRegistry.appendListeners（EventType.POST_COLLECTION_RECREATE，new CollectionRecreateEnversListener（enversConfiguration））; 
 listenerRegistry.appendListeners（EventType.PRE_COLLECTION_REMOVE，new PreCollectionRemoveEnversListener（enversConfiguration））; 
 listenerRegistry.appendListeners（EventType.PRE_COLLECTION_UPDATE，new PreCollectionUpdateEnversListener（enversConfiguration））; 
} 
 
} 
} 
  

步骤4 ：为了在Hibernate启动时自动使用集成器，您需要添加一个 META-INF / services / org.hibernate.integrator.spi.Interator 文件。这里是 org.hibernate.integrator.spi.Integrator 文件的内容

  com.hib.sample.listener.CustomEnversIntegrator 
  

我不确定，如果我缺少任何东西。我在Hibernate 4.1.8中使用JBOSS AS 7.0

解决方案

尝试将积分文件放入：

  sample.war\WEB-INF\classes\META-INF\services\ ... 
  




I have a requirement where I want to audit records only on change of Status field. I've followed documentation chapter tutorial "15.8. Conditional auditing".

Step 1: Turn off automatic Envers event listeners registration. I have following:

<prop key="hibernate.listeners.envers.autoRegister">false</prop>

Step 2: Create subclasses for appropriate event listeners.

public class DeleteEnversListener extends EnversPostDeleteEventListenerImpl {   
    private static final long serialVersionUID = 5906427978349712224L;
    private static Log log = LogFactory.getLog(DeleteEnversListener.class);

    public DeleteEnversListener(AuditConfiguration enversConfiguration) {
        super(enversConfiguration);
    }

    @Override
    public void onPostDelete(PostDeleteEvent event) {
        log.info("!!! just logging entity !! "+ event.getEntity());
        super.onPostDelete(event);
    }   
}

In similar way, I have

• InsertEnversListener
• UpdateEnversListener
• DeleteEnversListener
• CollectionRecreateEnversListener
• PreCollectionRemoveEnversListener
• PreCollectionUpdateEnversListener

Step 3: Create your own implementation of org.hibernate.integrator.spi.Integrator

public class CustomEnversIntegrator extends EnversIntegrator   {

    private static Log log = LogFactory.getLog(CustomEnversIntegrator.class);

    @Override
    public void integrate(Configuration configuration,
            SessionFactoryImplementor sessionFactory,
            SessionFactoryServiceRegistry serviceRegistry) {

        super.integrate(configuration, sessionFactory, serviceRegistry);
        final AuditConfiguration enversConfiguration = AuditConfiguration.getFor( configuration, serviceRegistry.getService( ClassLoaderService.class ) );
        EventListenerRegistry listenerRegistry = serviceRegistry.getService( EventListenerRegistry.class );

        System.out.println("Registering event listeners");
        if (enversConfiguration.getEntCfg().hasAuditedEntities()) {
            listenerRegistry.appendListeners(EventType.POST_INSERT, new InsertEnversListener(enversConfiguration));
            listenerRegistry.appendListeners(EventType.POST_UPDATE, new UpdateEnversListener(enversConfiguration));
            listenerRegistry.appendListeners(EventType.POST_DELETE, new DeleteEnversListener(enversConfiguration ) );
            listenerRegistry.appendListeners(EventType.POST_COLLECTION_RECREATE, new CollectionRecreateEnversListener(enversConfiguration ) );
            listenerRegistry.appendListeners(EventType.PRE_COLLECTION_REMOVE, new PreCollectionRemoveEnversListener(enversConfiguration ) );
            listenerRegistry.appendListeners(EventType.PRE_COLLECTION_UPDATE, new PreCollectionUpdateEnversListener(enversConfiguration ) );
        }

    }
}

Step 4: For the integrator to be automatically used when Hibernate starts up, you will need to add a META-INF/services/org.hibernate.integrator.spi.Integrator file. Here is content of org.hibernate.integrator.spi.Integrator file

com.hib.sample.listener.CustomEnversIntegrator

I am not sure, if I am missing anything. I am using JBOSS AS 7.0 with Hibernate 4.1.8

解决方案

Try to place integrator file into:

sample.war\WEB-INF\classes\META-INF\services\...
