java.lang.NoClassDefFoundError: org/hibernate/cfg/AnnotationConfiguration
提问by Renaud is Not Bill Gates
I've created a web dynamic project, and want to use Hibernatewith it.
我创建了一个 Web 动态项目，并想使用Hibernate它。
Then, I used the Hibernate Code Generationto generate classes code, and I created a class HibernateUtilwhere I initialize SessionFactory.
然后，我使用Hibernate Code Generation生成类代码，并创建了一个类HibernateUtil，在其中初始化SessionFactory.
public class HibernateUtil {
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory(){
try{
SessionFactory sessionFactory =
new AnnotationConfiguration().configure().buildSessionFactory();
return sessionFactory;
}catch(Exception ex){
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static void shutdown() {
getSessionFactory().close();
}
}
And another class HibernateSessionFactoryListener:
另一个类HibernateSessionFactoryListener：
public class HibernateSessionFactoryListener implements ServletContextListener{
@Override
public void contextInitialized(ServletContextEvent arg0) {
Session session = HibernateUtil.getSessionFactory().openSession();
System.out.println("\n Context Initilaise \n");
}
@Override
public void contextDestroyed(ServletContextEvent arg0) {
HibernateUtil.shutdown();
System.out.println("\n Context Detruit \n");
}
}
When I run my project I get this error message :

In Hibernate 3.6, “org.hibernate.cfg.AnnotationConfiguration” is deprecated, and all its functionality has been moved to “org.hibernate.cfg.Configuration“. So , you can safely replace your “AnnotationConfiguration” with “Configuration” class
在 Hibernate 3.6 中，“org.hibernate.cfg.AnnotationConfiguration”已被弃用，其所有功能已移至“org.hibernate.cfg.Configuration”。因此，您可以安全地将“AnnotationConfiguration”替换为“Configuration”类
