hibernate+spring中怎么得到connection

1，只要先得到sessionFactory对象
2，然后通过sessionFactory的子类SessionFactoryImplementor 的 getConnectionProvider() 来 得到ConnectionProvider
3，connectionProvider。getConnection();

ConnectionProvider cp = ((SessionFactoryImplementor)factory).getConnectionProvider();
Connection connection = cp.getConnection();
得到了connection对象，下面就是jdbc代码了

记得关闭资源

Configuration configuration = new Configuration();configuration.configure("hibernate.cfg.xml");ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder().applySettings(configuration                        .getProperties());SessionFactory sessionFactory = configuration                        .buildSessionFactory(serviceRegistryBuilder.buildServiceRegistry());session = sessionFactory.getCurrentSession();ConnectionProvider cp = ((SessionFactoryImplementor)sessionFactory).getConnectionProvider();Connection c = cp.getConnection();
