问题描述

我试图将Envers整合到我的项目中。我使用Hibernet-envers 3.5.5-Final，Hibernet-core 3.5.5-Final，spring 3.0.7.RELEASE。

对于DAO Layer， m使用GenericDaoHibernate类。



我的applicationContext.xml包含： 

 < property name =eventListeners> 
< map> 
< entry key =post-insert> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-delete> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-remove> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-collection-recreate> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< / map> 
< / property>

已创建注释类的审计表，但通过添加或更新实体表中的一行，没有行被插入到_AUD表或REVINFO中。



所以，我添加了一个新的监听器org.hibernate.ejb.event.EJB3PostInsertEventListener as：

 < property name =eventListeners> 
< map> 
< entry key =post-insert> 
< list> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< bean class =org.hibernate.ejb.event.EJB3PostInsertEventListener/> 
< / list> 
< / entry> 
< entry key =post-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-delete> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-remove> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-collection-recreate> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< / map> 
< / property>

问题依然存在，现在没有记录插入到实体表中。



欢迎任何建议。



谢谢。

解决方案好的。

我解决了这个问题。

首先，似乎用Hibernate-core 3.5.5-Final，我们不需要org.hibernate.ejb.event.EJB3PostInsertEventListener，所以在我们的ApplicationContext-config.xml中我们应该只有这个配置：

 < property name =eventListeners> 
< map> 
< entry key =post-insert> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-delete> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-update> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =pre-collection-remove> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< entry key =post-collection-recreate> 
< bean class =org.hibernate.envers.event.AuditEventListener/> 
< / entry> 
< / map> 
< / property>

其次，在我们的案例中，我们的项目使用了两个转换管理器，所以对于注释@Transactionnal的服务我们有提到所使用的正确的事务管理器的名称，这意味着所有服务都应该注释为@Transactionnal（value =NAME_TX_MANAGER）。这个问题的根源是，如果我们有一个自动提交（如果我理解了它的文档），Envers不能正常工作。



我希望这可能会有帮助对于其他游客如果面临同样的困难。

I'm trying to integrate Envers in my project. I'm using Hibernet-envers 3.5.5-Final, Hibernet-core 3.5.5-Final, spring 3.0.7.RELEASE.

For DAO Layer, I'm using a GenericDaoHibernate class.

My applicationContext.xml contains:

<property name="eventListeners">
                   <map>
                   <entry key="post-insert" >
                         <bean class="org.hibernate.envers.event.AuditEventListener" />
                 </entry>
                    <entry key="post-update">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="post-delete">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="pre-collection-update">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="pre-collection-remove">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="post-collection-recreate">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>  
                   </map>
                </property>

The audit tables for the annotated classes are created, but by adding or updating a row in the entity table, no row is inserted in the _AUD tables or in the REVINFO.

So, I added a new listener org.hibernate.ejb.event.EJB3PostInsertEventListener as :

<property name="eventListeners">
               <map>
               <entry key="post-insert" >
           <list>
             <bean class="org.hibernate.envers.event.AuditEventListener" />
             <bean class="org.hibernate.ejb.event.EJB3PostInsertEventListener" />
           </list>
       </entry>
                <entry key="post-update">
                 <bean class="org.hibernate.envers.event.AuditEventListener" />
               </entry>
                <entry key="post-delete">
                 <bean class="org.hibernate.envers.event.AuditEventListener" />
               </entry>
                <entry key="pre-collection-update">
                 <bean class="org.hibernate.envers.event.AuditEventListener" />
               </entry>
                <entry key="pre-collection-remove">
                 <bean class="org.hibernate.envers.event.AuditEventListener" />
               </entry>
                <entry key="post-collection-recreate">
                 <bean class="org.hibernate.envers.event.AuditEventListener" />
               </entry>  
               </map>
            </property>

The problem persists, and now no record is inserted in the entity tables.

Any suggestion is welcome.

Thanks.

解决方案

OK.

I solved the problem.

Firstibale, it seems that with the Hibernate-core 3.5.5-Final, we don't need org.hibernate.ejb.event.EJB3PostInsertEventListener, so in our ApplicationContext-config.xml we should have just this config :

<property name="eventListeners">
                   <map>
                   <entry key="post-insert" >
                         <bean class="org.hibernate.envers.event.AuditEventListener" />
                 </entry>
                    <entry key="post-update">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="post-delete">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="pre-collection-update">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="pre-collection-remove">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>
                    <entry key="post-collection-recreate">
                     <bean class="org.hibernate.envers.event.AuditEventListener" />
                   </entry>  
                   </map>
                </property>

Secondly, in our case our project uses two transction managers, so for the services annotated @Transactionnal we have to mention the name of the proper transaction manager used, that means that all services should be annotated as @Transactionnal(value="NAME_TX_MANAGER"). The source of this problem is that Envers doesn't work properly if we have an auto-commit (If I understood well its documentation).

I hope that may be helpful for the other visitors if the face the same difficulties.
