我有一個要求,只需要在狀態字段更改時審計記錄。我遵循了文檔章節教程「15.8。有條件的審計」。有條件的Envers審計

步驟1:關閉自動Envers事件監聽器註冊。我有以下內容:

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

第2步:爲適當的事件偵聽器創建子類。

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); 
    } 
} 

以類似的方式,我有

  • InsertEnversListener
  • UpdateEnversListener
  • DeleteEnversListener
  • CollectionRecreateEnversListener
  • PreCollectionRemoveEnversListener
  • PreCollectionUpdateEnversL istener

第3步:創建自己的實現的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)); 
     } 

    } 
} 

第4步:要當Hibernate啓動自動使用積分,您需要添加一個META-INF/services/org.hibernate.integrator.spi.Integrator文件。這裏是org.hibernate.integrator.spi.Integrator文件

com.hib.sample.listener.CustomEnversIntegrator 

的內容我不知道,如果我錯過什麼。我使用JBoss AS 7.0與Hibernate 4.1.8

目前發生了什麼? 您的定製集成商代碼是否已被調用? – adamw

@adamw:我已經將sysout語句添加到集成器代碼中,但沒有一個出現。看來服務不被JBOSS認可。我已經使用Eclipse 4.2 Juno作爲Dynamic Web項目創建了項目。 **不確定META-INF的位置是否正確**。任何建議.. –

你檢查了生成的jar/war,如果它有正確的地方的文件? – adamw

嘗試把積分文件到:

sample.war\WEB-INF\classes\META-INF\services\... 
0

也許......

就我而言,我使用Maven,我不得不包括在pom.xml中,以下行:<include>**/*.Integrator</include>,因爲該文件未打包在.ear中。

pom.xml

<resources> 
     <resource> 
      <directory>src/main/resources</directory> 
      <filtering>true</filtering> 
      <includes> 
       <include>**/*.xml</include> 
       <include>**/*.Integrator</include> 
      </includes> 
     </resource> 
     ... 
0

創建文件org.hibernate.integrator.spi.Integrator文件夾META-INF /服務/下(含我的自定義集成的限定名) 我的maven項目的src/main/resources使我的自定義集成器代碼被調用。
