Configuration.buildSessionFactory()过时之后，获取SessionFactory的写法

<span style="font-size:14px;">import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public final class HibernateUtil {
private HibernateUtil(){}
private static SessionFactory sessionFactory;
static{
Configuration cfg = new Configuration();
cfg.configure();

ServiceRegistry  sr = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry();
sessionFactory = cfg.buildSessionFactory(sr);
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static Session getSession(){
return sessionFactory.openSession();
}
}</span>
