hibernate4 -----AnnotationConfiguration类过期

Java code

package com.user.util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.[del]AnnotationConfiguration[/del];
public class HibernateUtil {
    public static SessionFactory sessionFactory;
    static {
        try{
        sessionFactory = new AnnotationConfiguration().configure().[del]buildSessionFactory();[/del]        }catch(Exception e){
            e.printStackTrace();
        }
    }
    public static SessionFactory getSessionFactory(){
        return sessionFactory;

    }
}

 
AnnotationConfiguration在hibernate 4版本中过期 请问是用那个代替了 而且在hibernate 4中找不到 AnnotationConfiguration这个类。代码中的[del][del]代表删除线——

------解决方案--------------------
Configuration configuration = new Configuration();
configuration.configure();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
SessionFactory sf = configuration.buildSessionFactory(serviceRegistry);
