public class HibernateUtil { private static final SessionFactory sessionFactory = buildSessionFactory(); private static SessionFactory buildSessionFactory() { try { Configuration configuration = new Configuration().configure(); ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder() .applySettings(configuration.getProperties()).build(); SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry); return sessionFactory; } catch (Throwable ex) { throw new ExceptionInInitializerError(ex); } } public static SessionFactory getSessionFactory() { return sessionFactory; } }

测试类

public class UserTest01{ @Test public void save(){ Configuration configuration=new Configuration(); configuration.configure(); SessionFactory sessionFactory=configuration.buildSessionFactory(); Session session=sessionFactory.openSession(); Transaction transaction=session.beginTransaction(); User user=new User(); user.setName("1"); session.save(user); transaction.commit();  session.close(); } }
