当我将Hibernate版本从3.6.8更新到4.0.0时，我在这一行中得到了关于已弃用方法buildSessionFactory()的警告:
private static final SessionFactory sessionFactory =
new Configuration().configure().buildSessionFactory();
Javadoc建议使用另一种方法
buildSessionFactory (ServiceRegistry ServiceRegistry)
但在文档中我发现了弃用的变体
当前回答
如果有人更新到5.1，这是它是如何工作的
StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure().build();
MetadataSources sources = new MetadataSources(registry);
Metadata metadata = sources.getMetadataBuilder().build();
sessionFactory = metadata.getSessionFactoryBuilder().build();
而不是hibernate 4.3中的下面
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()). buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
其他回答
道理很简单:JBoss文档并不是100%维护得很好。按照JavaDoc的说法:buildSessionFactory(ServiceRegistry ServiceRegistry)。
Tested on 4.2.7 release
package com.national.software.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import com.national.software.dto.UserDetails;
public class HibernateTest {
static SessionFactory sessionFactory;
public static void main(String[] args) {
// TODO Auto-generated method stub
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("user1");
Configuration config = new Configuration();
config.configure();
ServiceRegistry serviceRegistry = (ServiceRegistry) new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
sessionFactory = config.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}
是的，它被弃用了。用下面的代码替换你的SessionFactory:
在Hibernate 4.0, 4.1, 4.2
private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;
public static SessionFactory createSessionFactory() {
Configuration configuration = new Configuration();
configuration.configure();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()). buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
return sessionFactory;
}
更新:
在Hibernate 4.3中，ServiceRegistryBuilder已弃用。请使用以下语句。
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
configuration.getProperties()).build();
如果有人更新到5.1，这是它是如何工作的
StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure().build();
MetadataSources sources = new MetadataSources(registry);
Metadata metadata = sources.getMetadataBuilder().build();
sessionFactory = metadata.getSessionFactoryBuilder().build();
而不是hibernate 4.3中的下面
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
configuration.getProperties()). buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
公共无效sampleConnection()抛出异常{
Configuration cfg = new Configuration().addResource("hibernate.cfg.xml").configure();
StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
Session session = sessionFactory.openSession();
logger.debug(" connection with the database created successfuly.");
}
