Hibernate - ServiceRegistryBuilder

Question

Po prostu próbuję uczyć się Hibernate (wersja 4 final), ale mam problem podczas próby utworzenia fabryki sesji. Oto kod związany z problemem:

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; 
    } 
} 

Teraz, co wydaje się być problemem jest utworzenie ServiceRegistryBuilder. Gdy wykonanie kodu dostaje się do tego punktu, to daje mi następujący błąd:

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'.

Jak mogę rozwiązać ten problem? Nie mogę znaleźć rozwiązania samodzielnie.

Answer 1

To może być tylko nitpicking, ale proszę spróbować wymienić deklarację DOCTYPE w hibernate.cfg.xml z tym:

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

także zadeklarować nazwę sesji fabryce:

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

Answer 2

Oto nieaktualna metoda z konfiguracji, która wciąż działa. Wykonuje wiele ustawień hibernacji, których użytkownicy hibernacji nie chcą robić naprawdę. Rzeczy takie jak właściwości upraszczające i kopiowanie ich z jednego obiektu do drugiego. Szukałem również działającego przykładu konfiguracji Hibernate dla Hibernate 4, która nie używa przestarzałej metody buildSessionFactory() i nie udało się jej znaleźć. Uważam, że celem jest całkowita rezygnacja z konfiguracji.

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

W odpowiedzi hibernate 4.0.0. CR4: org.hibernate.internal.util.config.ConfigurationException with hibernate.cfg.xml, nowy sposób tworzenia SessionFactories jeszcze nie działa. Będzie gotowy w Hibernate 4.1.

Answer 4

Oto jak to działa z hibernacji 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> 

resztę konfiguracji pozostaje sam

Answer 5

natknąłem się na podobne problemy próbuje użyć Hibernacja 4.1.6.

Opierając się na przykład z RoseIndia.net, mam ServiceRegistryBuilder działa tak:

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

Mój plik hibernate.cfg.xml wykorzystuje stary plik DTD; Nie udało się uzyskać nowy plik XSD być uznawane przez 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> 

Być może można dostosować to do pracy dla Ciebie?

Answer 6

// hibernacji 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 jest ok

Answer 7

Od 4.3.0, nawet ServiceRegistryBuilder została zaniechana. To w jaki sposób chcesz zabrać

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

A także trzeba by importować org.hibernate.boot.registry.StandardServiceRegistryBuilder zamiast org.hibernate.service.ServiceRegistryBuilder

Answer 8

Metody buildSessionFactory i ServiceRegistryBuilder w Hibernate 4.3.4 są przestarzałe.

Właściwy kod jest tutaj.

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(); 
      ........

powinniśmy umieścić w folderze src hibernate.cfg.xml ..
