Hibernate – ServiceRegistryBuilder
我只是想学习Hibernate（最终版本4）但是在尝试创建会话工厂时我遇到了问题。 以下是与此问题相关的一些代码：
hibernate.cfg.xml中：
jdbc:mysql://localhost/fitterblog root com.mysql.jdbc.Driver 1 org.hibernate.dialect.MySQL5InnoDBDialect org.hibernate.transaction.JDBCTransactionFactory thread true <!-- --> 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，似乎问题是创建ServiceRegistryBuilder。 当代码执行到达那一点时，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: Cannot find the declaration of element 'hibernate-configuration'.

我该如何解决？ 我自己似乎无法找到解决方案。
不推荐使用Hibernate 4.3.4中的方法buildSessionFactory和ServiceRegistryBuilder 。
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(); ........
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());
而且你必须导入org.hibernate.boot.registry.StandardServiceRegistryBuilder而不是org.hibernate.service.ServiceRegistryBuilder
以下是hibernate 4.x的工作原理
......
其余配置保持不变
我在尝试使用Hibernate 4.1.6时遇到了类似的问题。
基于RoseIndia.net的一个例子，我让ServiceRegistryBuilder像这样工作：
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文件使用旧的DTD文件; 我无法让Hibernate 4.1.6识别新的XSD文件：
...
也许你可以适应这个为你工作？
对于以下错误：
Oct 09, 2015 12:29:53 AM org.hibernate.Version logVersion INFO: HHH000412: Hibernate Core {5.0.2.Final} Oct 09, 2015 12:29:53 AM org.hibernate.cfg.Environment INFO: HHH000206: hibernate.properties not found Oct 09, 2015 12:29:53 AM org.hibernate.cfg.Environment buildBytecodeProvider INFO: HHH000021: Bytecode provider name : javassist Exception in thread "main" org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml] at org.hibernate.boot.cfgxml.internal.ConfigLoader.loadConfigXmlResource(ConfigLoader.java:53) at org.hibernate.boot.registry.StandardServiceRegistryBuilder.configure(StandardServiceRegistryBuilder.java:163) at org.hibernate.cfg.Configuration.configure(Configuration.java:259) at org.hibernate.cfg.Configuration.configure(Configuration.java:245) at org.hibernate.ClientResource.ClientTest.main(ClientTest.java:17)
我们应该将hibernate.cfg.xml放在src文件夹中。
它可能只是挑剔，但请尝试用以下方法替换hibernate.cfg.xml中的DOCTYPE声明：
另外，声明会话工厂的名称：
以下是Configuration中不推荐使用的方法。 它正在做很多hibernate特定的设置，hibernate用户不会真的想做。 像通知属性和将它们从一个对象复制到另一个对象的事情。 我一直在寻找Hibernate 4的Hibernate配置的一个工作示例，该配置不使用已弃用的buildSessionFactory（）方法，到目前为止无法找到它。 我认为其目的是完全弃用配置。
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 ); }
正如hibernate 4.0.0中所回答的那样。 使用hibernate.cfg.xml的CR4：org.hibernate.internal.util.config.ConfigurationException ，创建SessionFactories的新方法还不行。 它将在Hibernate 4.1中准备就绪。

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();
//测试没问题
