在Spring+Hibernate的環境中如何通過編程模式來實現數據庫連接？

在Spring+Hibernate的環境中如何通過編程模式來實現數據庫連接？

[code]public class LocalSessionFactoryBeanTest {


public static DataSource getDataSource(){

BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
ds.setUrl("jdbc:microsoft:sqlserver://192.168.0.100:1433;DatabaseName=CMCS3");
ds.setUsername("sa");
ds.setPassword("developer");

return (DataSource)ds;

}

public static SessionFactory getSessionFactory(DataSource ds) {

LocalSessionFactoryBean factory = new LocalSessionFactoryBean();


Properties p = new Properties();
p.put("hibernate.dialect", "org.hibernate.dialect.SQLServerDialect");
p.put("hibernate.show_sql", "true");


Properties p1 = new Properties();
ArrayList<String> list = new ArrayList<String>();
list.add("classpath*:com/sky/frame/domain/*.hbm.xml");
p1.put("mappingLocations", list);

factory.setDataSource(ds);
factory.setHibernateProperties(p);

return (SessionFactory)factory.getObject();
}

public static void main(String[] args){
DataSource ds = getDataSource();
SessionFactory sf = getSessionFactory(ds);
Session session = sf.openSession();
System.out.println(session.toString());
session.close();
}[/code]

似乎這樣可以，但是最是不能通過factory.getObject()獲得SessionFactory,而是得到Null。哪裏有問題？大家給看看。
