Hibernate - ServiceRegistryBuilder

Question

Sto solo cercando di imparare Hibernate (versione 4 final) ma ho un problema quando provo a creare la factory di sessione. Ecco il codice relativo al problema:

hibernate.cfg.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
<session-factory> 
    <property name="connection.url">jdbc:mysql://localhost/fitterblog</property> 
    <property name="connection.username">root</property> 
    <property name="connection.password"></property> 
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 

    <property name="connection.pool_size">1</property> 
    <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> 
    <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property> 
    <property name="current_session_context_class">thread</property> 
    <property name="show_sql">true</property> 

    <!--<mapping class="com.fitterblog.objects.Article"/> 
    <mapping class="com.fitterblog.objects.Nav"/> 
    <mapping class="com.fitterblog.objects.Tag"/> 
    <mapping class="com.fitterblog.objects.User"/>--> 

</session-factory> 
</hibernate-configuration> 

HibernateUtil.java:

public class HibernateUtil { 

    private static final SessionFactory sessionFactory = buildSessionFactory(); 

    private static SessionFactory buildSessionFactory() { 
     try { 
      // Create the SessionFactory from hibernate.cfg.xml 

      ServiceRegistryBuilder srb = new ServiceRegistryBuilder(); 

      //NOTE: THIS IS WHERE MY PROGRAM DIES!! 
      srb = srb.configure(); 

      ServiceRegistry sr = srb.buildServiceRegistry(); 
      MetadataSources mds = new MetadataSources(sr); 
      /*mds.addAnnotatedClass(com.fitterblog.objects.Article.class); 
      mds.addAnnotatedClass(com.fitterblog.objects.Nav.class); 
      mds.addAnnotatedClass(com.fitterblog.objects.Tag.class); 
      mds.addAnnotatedClass(com.fitterblog.objects.User.class);*/ 
      return mds.buildMetadata().buildSessionFactory(); 
     } catch (Throwable ex) { 
      System.err.println("Initial SessionFactory creation failed." + ex); 
      throw new ExceptionInInitializerError(ex); 
     } 
    } 

    public static SessionFactory getSessionFactory() { 
     return sessionFactory; 
    } 
} 

Ora, quello che sembra essere il problema sta creando ServiceRegistryBuilder. Quando il codice di esecuzione arriva a quel punto, mi dà il seguente errore:

org.hibernate.internal.util.config.ConfigurationException: 
Unable to perform unmarshalling at line number 14 and 
column 26 in RESOURCE hibernate.cfg.xml. Message: cvc-elt.1: 
Cannot find the declaration of element 'hibernate-configuration'.

Come posso risolvere questo problema? Non riesco a trovare una soluzione da solo.

Answer 1

Potrebbe essere solo fare i difficili, ma si prega di provare a sostituire la dichiarazione DOCTYPE in hibernate.cfg.xml con questo:

<!DOCTYPE hibernate-configuration PUBLIC 
"-//Hibernate/Hibernate Configuration DTD//EN" 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 

Inoltre, dichiarano un nome per la sessione in fabbrica:

<session-factory name="java:hibernate/SessionFactory"> 

Answer 2

Ecco il metodo deprecato da Configuration che funziona ancora. Sta facendo un sacco di impostazioni specifiche di ibernazione che gli utenti in letargo non vorrebbero davvero fare. Cose come proprietà di pulizia e copia da un oggetto a un altro. Ho anche cercato un esempio funzionante di configurazione di Hibernate per Hibernate 4 che non utilizza il metodo buildSessionFactory() deprecato e non è stato possibile trovarne uno finora. Credo che l'intento sia di deprecare completamente la configurazione.

public SessionFactory buildSessionFactory() throws HibernateException { 
    Environment.verifyProperties(properties); 
    ConfigurationHelper.resolvePlaceHolders(properties); 
    final ServiceRegistry serviceRegistry = new ServiceRegistryBuilder() 
      .applySettings(properties) 
      .buildServiceRegistry(); 
    setSessionFactoryObserver(
      new SessionFactoryObserver() { 
       @Override 
       public void sessionFactoryCreated(SessionFactory factory) { 
       } 

       @Override 
       public void sessionFactoryClosed(SessionFactory factory) { 
        ((StandardServiceRegistryImpl) serviceRegistry).destroy(); 
       } 
      } 
    ); 
    return buildSessionFactory(serviceRegistry); 
} 

Answer 3

Come rispose hibernate 4.0.0. CR4: org.hibernate.internal.util.config.ConfigurationException with hibernate.cfg.xml, il nuovo modo di creare SessionFactories non funziona ancora. Sarà pronto in Hibernate 4.1.

Answer 4

Ecco come funziona con Hibernate 4.x

<?xml version='1.0' encoding='utf-8'?> 
<hibernate-configuration xmlns="http://www.hibernate.org/xsd/hibernate-configuration"> 
    <session-factory name="java:hibernate/SessionFactory"><!-- Name is Optional --> 
...... 
</session-factory> 
</hibernate-configuration> 

resto della configurazione rimane stesso

Answer 5

ho incontrato problemi simili che cercano di usare Hibernate 4.1.6.

costruzione su un esempio da RoseIndia.net, ho ottenuto ServiceRegistryBuilder a lavorare in questo modo:

Configuration config = new Configuration(); 
config.configure(); 
ServiceRegistryBuilder srBuilder = new ServiceRegistryBuilder(); 
srBuilder.applySettings(config.getProperties()); 
ServiceRegistry serviceRegistry = srBuilder.buildServiceRegistry(); 
SessionFactory factory = config.buildSessionFactory(serviceRegistry); 

Il mio file hibernate.cfg.xml utilizza il vecchio file DTD; Non sono stato in grado di ottenere il nuovo file XSD di essere riconosciuto da Hibernate 4.1.6:

<?xml version="1.0" encoding="utf-8"?> 
<!DOCTYPE hibernate-configuration PUBLIC 
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 
     ... 
    </session-factory> 
</hibernate-configuration> 

Forse si può adattare questo a lavorare per voi?

Answer 6

// ibernazione 4 构建 sessionFactory 方式 email 563143188@qq.com

Configuration cfg = new Configuration() 
      .configure("hibernate.cfg.xml"); 

    SessionFactory sf = cfg.buildSessionFactory(new ServiceRegistryBuilder() 
      .applySettings(cfg.getProperties()).build()); 
    //build() return buildServiceRegistry 
    Session s = sf.openSession(); 

// test è ok

Answer 7

A partire dal 4.3.0, anche ServiceRegistryBuilder è stato sconsigliato. Questo è come si vorrebbe andare a questo proposito

Configuration cfg=new Configuration().configure(); 
StandardServiceRegistryBuilder builder= new StandardServiceRegistryBuilder().applySettings(
      cfg.getProperties()); 
SessionFactory factory= cfg.buildSessionFactory(builder.build()); 

E anche che avrebbe dovuto importare org.hibernate.boot.registry.StandardServiceRegistryBuilder invece di org.hibernate.service.ServiceRegistryBuilder

Answer 8

I metodi buildSessionFactory e ServiceRegistryBuilder in Hibernate 4.3.4 sono deprecati.

Il codice giusto è qui.

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.service.ServiceRegistry; 
import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 


..... 

    Configuration conf = new Configuration() 
       .configure(); 


    ServiceRegistry sr = new StandardServiceRegistryBuilder().applySettings(conf.getProperties()).build(); 


    SessionFactory sf = conf.buildSessionFactory(sr); 

    Session session = sf.openSession(); 

    session.beginTransaction(); 


    YourDominClass ydc = new YourDominClass(); 

    ydc.setSomething("abcdefg"); 

    session.save(ydc); 

    session.getTransaction().commit(); 

    session.close(); 

    sf.close(); 
      ........

per l'errore di seguito:

dovremmo collocare la hibernate.cfg.xml nella cartella src ..
