Hibernate的Load问题
首先，数据库里有记录，但用Junit测试Load方法时报org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.hibernate.Teacher#2]

具体代码是：
@Test
public void Load(){
Session session=sf.getCurrentSession();
session.beginTransaction();
Teacher t=(Teacher)session.load(Teacher.class, 2);
System.out.println(t.getName());
session.getTransaction().commit();
}
@Test
public void Get(){
Session session=sf.getCurrentSession();
session.beginTransaction();
Teacher t=(Teacher)session.get(Teacher.class, 2);
System.out.println(t.getName());
session.getTransaction().commit();
}
Get同样是，测试完后数据库的数据就丢失了！！各位大虾帮帮忙吧！！
