添加自定义事件监听器（Hibernate）会抛出org.hibernate.MappingException：无法实例化指定的事件（保存更新）监听器类

标签： java hibernate jboss5.x

我正在尝试在我的项目中为（UPDATE，INSERT）添加自定义事件侦听器。以下是我的代码片段。

hibernate.cfg.xml文件条目：

<event type="post-insert">
    <listener class="sample.org.app.MyProjectAdaptorHibEventListener"/>
</event>
<event type="save-update">
    <listener class="sample.org.app.MyProjectAdaptorHibEventListener"/>
</event>

和MyProjectAdaptorHibEventListener实现代码段：

public class MyProjectAdaptorHibEventListener implements PostInsertEventListener,
    PostUpdateEventListener, PostDeleteEventListener,
    SaveOrUpdateEventListener {

private static final long serialVersionUID = 400000L;
private MyProjectAdaptorHibEventListenerUtil util;

public MyProjectAdaptorHibEventListener() {
    util = new MyProjectAdaptorHibEventListenerUtil();
    System.out.println("*************   MyProjectAdaptorHibEventListener loaded **************");
}

@Override
public void onPostDelete(PostDeleteEvent event) {
    util.objectChanged("DELETE", event.getEntity());

}

@Override
public void onPostUpdate(PostUpdateEvent event) {

    util.objectChanged("UPDATE", event.getEntity());

}

@Override
public void onPostInsert(PostInsertEvent event) {
    util.objectChanged("INSERT", event.getEntity());

}

@Override
public void onSaveOrUpdate(SaveOrUpdateEvent event)
        throws HibernateException {
    util.objectChanged("SAVEORUPDATE", event.getObject());

  }
}

和我的MyProjectAdaptorHibEventListenerUtil代码：

public class MyProjectAdaptorHibEventListenerUtil {

MyProjectAdaptorHibEventListenerUtil(){        
}

public void objectChanged(String event, Object object) {

    if (object instanceof AbstractDomainObject && ! object.getClass().getName().startsWith("edu.wustl.common.domain.Audit")) {
        long objId = ((AbstractDomainObject) object).getId();
        System.out.println("*********** " + event + " : " + object.getClass().getName()+ ":" + objId + " , value= " + object.toString());
        insertIntoDB(event,object.getClass().getName(),objId);
    }else{
       // System.out.println("*********** " + event + " : " + object.getClass().getName());
    }
  }
}

我不确定我的代码有什么问题。请告诉我这些变化。我收到了以下错误。

我正在使用 Hibernate 3 Jboss- 5.1.0 GA Java - 1.6

我认为你的xml存在问题。据我所知，没有事件类型： insert（至少不在hibernate v3.3中）但是有以下类型（以及需要实现的接口）：

"auto-flush"- AutoFlushEventListener
"merge", MergeEventListener
"create", PersistEventListener
"create-onflush", PersistEventListener
"delete", DeleteEventListener
"dirty-check", DirtyCheckEventListener
"evict", EvictEventListener
"flush", FlushEventListener
"flush-entity", FlushEntityEventListener
"load", LoadEventListener
"load-collection", InitializeCollectionEventListener
"lock", LockEventListener
"refresh", RefreshEventListener
"replicate", ReplicateEventListener
"save-update", SaveOrUpdateEventListener
"save", SaveOrUpdateEventListener
"update", SaveOrUpdateEventListener
"pre-load", PreLoadEventListener
"pre-update", PreUpdateEventListener
"pre-delete", PreDeleteEventListener
"pre-insert", PreInsertEventListener
"pre-collection-recreate", PreCollectionRecreateEventListener
"pre-collection-remove", PreCollectionRemoveEventListener
"pre-collection-update", PreCollectionUpdateEventListener
"post-load", PostLoadEventListener
"post-update", PostUpdateEventListener
"post-delete", PostDeleteEventListener
"post-insert", PostInsertEventListener
"post-commit-update", PostUpdateEventListener
"post-commit-delete", PostDeleteEventListener
"post-commit-insert", PostInsertEventListener
"post-collection-recreate", PostCollectionRecreateEventListener
"post-collection-remove", PostCollectionRemoveEventListener
"post-collection-update", PostCollectionUpdateEventListener

所以我认为你应该使用＆＃34; post-insert＆＃34;因为这种类型会使你的监听器重新实现PostInsertEventListener（你实现的那个）

我看到你收到的这个异常的根本原因是java.lang.ArrayStoreException，而作为javadoc状态，它是

  

抛出表示已尝试存储错误   对象类型为对象数组。例如，以下内容   代码生成一个ArrayStoreException：

    Object x[] = new String[3];
    x[0] = new Integer(0);

请提供MyProjectAdaptorHibEventListener
