我试图在我的项目中实现Hibernate的PreUpdateEventListener,但没有任何反应。
我的configuration.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<event type="pre-update">

</event>
</session-factory>

My MyHibernateEventListener类:
import javax.swing.JOptionPane;
import org.hibernate.event.spi.PreUpdateEvent;
import org.hibernate.event.spi.PreUpdateEventListener;
/**
*
* @author Maycon
*/
public class MyHibernateEventListener implements PreUpdateEventListener {
public MyHibernateEventListener() {
this.atencao();
}
public void atencao() {
System.out.println("EEEEUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU\n\n");
JOptionPane.showMessageDialog(null, "MyLoadListener");
}
@Override
public boolean onPreUpdate(PreUpdateEvent pue) {
this.atencao();
return true;
}
}
结果:控制台没有显示任何内容。
答案 0 :(得分:0)
也许这不再相关,但是您必须添加以下代码:
@PostConstruct
protected void init(){
SessionFactoryImpl sF = emf.unwrap(SessionFactoryImpl.class);
EventListenerRegistry registry = sF.getServiceRegistry().getService(EventListenerRegistry.class);
registry.getEventListenerGroup(EventType.PRE_UPDATE).appendListener(this);
}
