实现条件Envers审计(Hibernate 4.3.7.Final)

标签: hibernate hibernate-envers

我想审核实体中的所有属性,但仅限于某些属性已更改。 按照文档(here)中描述的步骤,我创建了自己的EnversIntegrator实现:

public class EnversIntegrator extends org.hibernate.envers.event.spi.EnversIntegrator {
private static final Logger log = LoggerFactory.getLogger(EnversIntegrator.class);  
private AuditConfiguration enversConfiguration;
@Override
public void integrate(Configuration configuration, SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) {
    log.debug(".... integrate");
    final EventListenerRegistry listenerRegistry = serviceRegistry.getService(EventListenerRegistry.class);
    listenerRegistry.addDuplicationStrategy(EnversListenerDuplicationStrategy.INSTANCE);
    enversConfiguration = AuditConfiguration.getFor(configuration, serviceRegistry.getService(ClassLoaderService.class));
    if (enversConfiguration.getEntCfg().hasAuditedEntities()) {
        log.debug(".... Register listeners");
        listenerRegistry.prependListeners(EventType.POST_DELETE, new MyPostDeleteEventListener(enversConfiguration));
        listenerRegistry.prependListeners(EventType.POST_INSERT, new MyPostInsertEnversEventListener(enversConfiguration));
        listenerRegistry.prependListeners(EventType.POST_UPDATE, new  MyPostUpdateEnversEventListener(enversConfiguration));
    }
}
@Override
public void disintegrate(SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) {
    if (enversConfiguration != null) {
        enversConfiguration.destroy();
    }
}

其中:

MyPostInsertEnversEventListener extends org.hibernate.envers.event.spi.EnversPostInsertEventListenerImpl

 MyPostUpdateEnversEventListener extends org.hibernate.envers.event.spi.EnversPostUpdateEventListenerImpl

覆盖onPostUpdate或onPostInsert(PostInsertEvent evt)无效,每次执行测试时,都会在_AUD表中添加新记录。

public void onPostUpdate(PostUpdateEvent evt) {     
    LOG.debug(" ... onPostUpdate " + evt.getEntity().getClass());
//here is my logic who decide if the super.onPostUpdate(evt) must be call or not  
//But NO  super.onPostUpdate(evt); is called !!!!!

}

更新地址实体booth onPostUpdate和onPostInsert:

[DEBUG] xxxx.hibernate.MyPostUpdateEnversEventListener -  ... onPostUpdate class xxxxxxx.model.Address
[DEBUG] xxxx.hibernate.MyPostInsertEnversEventListener -  ... onPostInsert class org.hibernate.envers.DefaultRevisionEntity
[DEBUG] xxxx.hibernate.MyPostInsertEnversEventListener -  ... onPostInsert class java.util.HashMap

如何在_aud表中阻止创建新记录?

非常感谢!

您需要子类化事件侦听器,例如PostInsertEnversEventListener,在那里进行条件审核检查,如果检查通过,则调用super方法。

调试代码我已经意识到"整合" org.hibernate.envers.event.spi.EnversIntegrator中的方法也被调用。事实上,我错放了" hibernate.listeners.envers.autoRegister "弹簧配置中的参数。这是我的工作配置:

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="myTestDataSource" />
    <property name="packagesToScan" value="xyz.**.model" />

    <property name="jpaVendorAdapter" ref="jpaAdapter" />
    <property name="jpaProperties">
        <props>             
                      <prop key="hibernate.hbm2ddl.auto">validate</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.format_sql">true</prop>
            <prop key="hibernate.listeners.envers.autoRegister">false</prop>
        </props>
    </property>
    <property name="persistenceXmlLocation"
        value="classpath:spring/app-persistence.xml" />
</bean>

亚当四,你的伟大工作。

对于较新版本,该媒体资源为 hibernate.envers.autoRegisterListeners ,而不是hibernate.listeners.envers.autoRegister
最后一个只是遗留的。您可以检查EnversIntegratorEnversServiceImpl类。

对于春季靴子,你可以设置:

spring.jpa.properties.hibernate.envers.autoRegisterListeners=false
