  导入的jar包和程序不匹配，你把本节课的老师上传的资料下载下来，里面有hibernate3的jar包，导入到自己的项目就可以了！希望采纳！！

  太老了，可以自己写工具类代码：

  package com.imooc.util;

  
  

  
  

  
  

  
  

  import org.hibernate.Transaction;

  import org.hibernate.Session;

  import org.hibernate.SessionFactory;

  import org.hibernate.cfg.Configuration;

  
  

  public class HibernateSessionFactory {

  private static SessionFactory sessionFactory;

  private static Session session;

  private static Transaction transaction;

  static{

  Configuration config = new Configuration().configure();// 鍒涘缓閰嶇疆瀵硅薄

  sessionFactory = config.buildSessionFactory();// 鍒涘缓浼氳瘽宸ュ巶瀵硅薄

  // session = sessionFactory.openSession();// 鎵撳紑浼氳瘽

  // transaction = session.beginTransaction();// 寮�惎浜嬪姟

  }

  //鑾峰彇session

  public static Session getSession(){

  session=sessionFactory.openSession();

  return session;

  }

  
  

  public static void closeSession(Session session){

  if(session!=null){

  session.close();

  }

  }

  }

  方法已经过时了，你试试session.isConnected()
