hibernate4按照帮助文档配置了好久没有成功的问题

帮助文档源代码：

public class HibernateUtil {

private static final SessionFactory sessionFactory = buildSessionFactory();

private static SessionFactory buildSessionFactory() {
try {
// Create the SessionFactory from hibernate.cfg.xml
new Configuration().configure().buildSessionFactory(
new StandardServiceRegistryBuilder().build() );
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}

public static SessionFactory getSessionFactory() {
return sessionFactory;
}

}

将hibernate配置通的代码：

public class HibernateUtil {

public static SessionFactory getMySessionFactory(){

StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();

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

serviceRegistryBuilder.applySettings(configuration.getProperties());//添加了这样一个配置，按理说serviceRegistryBuilder默认就应该有的。但是没有

SessionFactory sessionFacotry = configuration.buildSessionFactory(

serviceRegistryBuilder.build() );

return sessionFacotry;

}

}

只有可以利用sessionFactory得到session然后使用hibernate；

希望大家多提意见
