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）
<强> OLD
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
