代码：

public class HibernateUtil {
 private static SessionFactory  sf;
 private static ApplicationContext ctx;
 
 public static SessionFactory getSessionFactory(){
  ctx = new FileSystemXmlApplicationContext("conf/appConfig.xml");  
  sf = (SessionFactory) ctx.getBean("sessionFactory");  
  return sf;
 }

}

public class UserDaoImpl  implements UserDao {

 public void save(HibernateUser user) {


  SessionFactory sf =  HibernateUtil.getSessionFactory();
  Session s =sf.getCurrentSession();
  s.beginTransaction();
  s.save(user);
  s.getTransaction().commit();
  s.close();
 }

红色部分，为报错部分，不知道如何解决！
