Answer 1

运行
SessionFactory sf=config.buildSessionFactory(sr); 
出的错

Answer 2

 Configuration config=new Configuration().configure();      \
这句话好像错了
 Configuration config=new Configuration();
 config.configure();//默认加载hibernate.cfg.xml的配置文件 
你仔细想想这两者的区别 。

Answer 3

public class FirstHibernate {     public static void main(String[] args) {                   //1.使用configuration初始化hibernate读取配置文件         Configuration config=new Configuration();         config.configure();//默认加载hibernate.cfg.xml的配置文件         //config.configure("hibernate.cfg.xml");//配置文件自定义配置         //2构建sessionfactory         SessionFactory fac=config.buildSessionFactory();                   //3生成session         Session session=fac.openSession();//使用默认session         //4.开始事务         Student s=new Student();         s.setId(1);         s.setName("briup");         s.setAddress("briup");         s.setAge(12);          Transaction tr=session.beginTransaction();         session.save(s);//提交操作s         //save delete update                   tr.commit();         session.close();               } }

Answer 4

//1.使用configuration初始化hibernate读取配置文件 
 Configuration config=new Configuration(); 
config.configure();//默认加载hibernate.cfg.xml的配置文件 
 //config.configure("hibernate.cfg.xml");//配置文件自定义配置 
//2构建sessionfactory 
SessionFactory fac=config.buildSessionFactory(); 
 //3生成session 
 Session session=fac.openSession();//使用默认session 
  //4.开始事务 
Student s=new Student(); 
s.setId(1);         
s.setName("briup");         
s.setAddress("briup");         
s.setAge(12);          
Transaction tr=session.beginTransaction(); 
session.save(s);//提交操作s         
//save delete update                   
tr.commit();         
session.close(); 
如果还有问题的话，就是你hibernate.cfg.xml有问题了

Answer 5

4.1.8 不让用buildSessionFactory() 方法了

Answer 7

File file = new File("F:\\workspace\\hibernate\\src\\hibernate.cfg.xml");    2 Configuration config = new Configuration().configure(file);           3 ServiceRegistry sr = new ServiceRegistryBuilder().applySettings(    4                         config.getProperties()).buildServiceRegistry();    5 sessionFactory = config.buildSessionFactory(sr); 路径改成绝对的，再试试，如果还不行，那我就真没办法了。

Answer 8

  Could not load requested class  ： oracle.jdbc.driver.OracleDriver 
  
你确定你引入了oracle驱动 的jar包？  貌似是classes14.jar吧  我也忘了、oracle 10的jar包还真不知道、如果你确定你引入了oracle驱动的jar、那么就是他运行的时候找不到该jar的路径

Answer 9

没引oracle jar包。
我都快哭了 谢谢各位

Answer 10

以后出错了要记得 看错误信息、别怕英文不英文、
Caused by 引起错误原因、
实在不行就翻译、最后就知道大概是什么错了、
