Hibernate - ServiceRegistryBuilder

java hibernate hibernate.cfg.xml

2022-09-02 11:43:36

我只是试图学习Hibernate（版本4最终版本），但在尝试创建会话工厂时遇到了问题。以下是一些与该问题相关的代码：

休眠.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;
    }
}

现在，问题似乎在于创建ServiceRegistryBuilder。当代码执行达到该点时，它会给我以下错误：

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:

如何解决此问题？我自己似乎找不到解决方案。

答案 1

Hibernate 4.3.4 中的 buildSessionFactory 和 ServiceRegistryBuilder 方法已弃用。

正确的代码在这里。

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();
            ........

答案 2

从4.3.0开始，甚至ServiceRegistryBuilder也被弃用了。这就是你想要的方式

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

而且，您还必须导入而不是org.hibernate.boot.registry.StandardServiceRegistryBuilderorg.hibernate.service.ServiceRegistryBuilder
