Hibernate - ServiceRegistryBuilder

javahibernatehibernate.cfg.xml
19

我只是想学习Hibernate（4.0最终版本），但在创建会话工厂时遇到了问题。以下是与该问题相关的一些代码：

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">

    <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.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，问题似乎出在创建ServiceRegistryBuilder上。当代码执行到该点时，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:

我该如何修复这个问题？我自己似乎找不到解决方案。

目前，我只是使用以下代码来生成SessionFactory：“new AnnotationConfiguration().configure().buildSessionFactory();”。它可以工作，但已被弃用，因此如果可能的话，我想避免使用它。 - Fittersman

Hibernate 4.3.4中的buildSessionFactory和ServiceRegistryBuilder方法已被弃用。

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();
            ........

截至4.3.0版本，连ServiceRegistryBuilder都已被弃用。以下是您应该采取的方法

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

还有你需要导入org.hibernate.boot.registry.StandardServiceRegistryBuilder而不是org.hibernate.service.ServiceRegistryBuilder

上述配置未能读取我的映射，但下面的变体却可以。 ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder(). configure().loadProperties("hibernate.cfg.xml").build(); sessionFactory = new Configuration().buildSessionFactory(serviceRegistry); - veritas

我在尝试使用Hibernate 4.1.6时遇到了类似的问题。

借鉴自RoseIndia.net的示例，我按照如下方式使ServiceRegistryBuilder工作：

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

我的hibernate.cfg.xml文件使用了旧的DTD文件，我一直无法让Hibernate 4.1.6识别新的XSD文件:

<?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>

也许您可以将此适应到适合您的工作中？

以下是Hibernate 4.x的工作方式：

<?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>

其余的配置保持不变。

我们应该将 hibernate.cfg.xml 放置在 src 文件夹中。

这里有一个从Configuration过期的方法，但仍然有效。它正在进行许多针对Hibernate具体设置的操作，而Hibernate用户实际上并不需要执行这些操作。例如验证属性并将其从一个对象复制到另一个对象。我也一直在寻找一个使用不过期的buildSessionFactory（）方法的Hibernate 4配置的工作示例，但迄今为止还没有找到。我相信意图是完全弃用Configuration。
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 );
}

可能只是吹毛求疵，但请尝试将 hibernate.cfg.xml 中的 DOCTYPE 声明替换为以下内容：

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

此外，为会话工厂声明一个名称：

<session-factory name="java:hibernate/SessionFactory">
谢谢回复，但是那似乎对我没有任何帮助。还有其他的想法吗？ - Fittersman
好的，日志显示hibernate.cfg.xml有错误，但是从这里看起来一切都正常。也许是文件的编码有问题？请确保它真的是UTF-8。 - Óscar López
我不是很确定，我开始怀疑是否存在某个错误，因为在网上阅读了一段时间后，这是我的印象。目前，我将继续使用旧的获取会话工厂的方式。很遗憾，因为似乎没有人能提供答案，所以稍后我会再次尝试使用新的方法 :) - Fittersman
