会话工厂创建使用注册表和元数据的Hibernate 5.0.7

Question

我已经附加了我的代码，它根本没有创建sessionfactory，请看看它，让我知道我错了什么地方。

HibernateUtilities.java

package com.yashwanth.HIbernate; 

import org.hibernate.HibernateException; 
import org.hibernate.SessionFactory; 
import org.hibernate.boot.Metadata; 
import org.hibernate.boot.MetadataSources; 
import org.hibernate.boot.model.naming.ImplicitNamingStrategyJpaCompliantImpl; 
import org.hibernate.boot.registry.StandardServiceRegistry; 
import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.service.ServiceRegistry; 

public class HIbernateUtilities { 
private static SessionFactory sessionFactory; 
private static ServiceRegistry serviceRegistry; 

public SessionFactory setUp() throws Exception 
{ 

     final StandardServiceRegistry registry = new StandardServiceRegistryBuilder() 
       .configure() // configures settings from hibernate.cfg.xml 
       .build(); 

      sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory(); 

     /*catch (Exception e) { 
      // The registry would be destroyed by the SessionFactory, but we had trouble building the SessionFactory 
      // so destroy it manually. 
      StandardServiceRegistryBuilder.destroy(registry); 
     }*/ 
return sessionFactory; 
} 
} 

这里是另外一个Java类：提前

package com.yashwanth.HIbernate; 
import org.hibernate.HibernateException; 
import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
public class Program { 
public static void main(String[] args) throws HibernateException, Exception 
    { 
     System.out.println("yashpotu"); 
     HIbernateUtilities Utility =new HIbernateUtilities(); 
     SessionFactory sessionFactory=Utility.setUp(); 

     Session session = sessionFactory.openSession(); 
     session.beginTransaction(); 
     User user=new User(); 
     user.setName("YASH"); 
     user.setGoal(250); 
     session.save(user); 
     session.getTransaction().commit(); 
     session.close(); 
     sessionFactory.close(); 
     } 

     }

For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

谢谢，请让我知道我在哪里出了错

try { 
     Configuration configuration = new Configuration().configure(); 

     ServiceRegistry registry = new StandardServiceRegistryBuilder() 
       .applySettings(configuration.getProperties()).build(); 
     return new MetadataSources(registry).buildMetadata().buildSessionFactory(); 
    } catch (Throwable cause) { 
     System.err.println("Initial SessionFactory creation failed: " + cause); 
     throw new ExceptionInInitializerError(cause); 
    }
