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 实现代码片段：
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。请建议我进行更改。我收到以下错误。
我正在使用 Hibernate 3 Jboss- 5.1.0 GA Java - 1.6
