1、错误描述

Exception in thread "main" org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [com.you.hibernate.model.TStudentInfo#1]

2、错误原因

public static void deleteStuInfo(int id)
    {
        Session session = HibernateSessionFactory.getSession();
        session.beginTransaction();
        TStudentInfo student = (TStudentInfo)session.load(TStudentInfo.class, id);
        session.delete(student);
        session.getTransaction().commit();
        System.out.println("删除成功！");
    }
/**    
     * 方法描述：

     * 方法名称：main
     * 方法类型：StudentDao

     */
    public static void main(String[] args) 
    {
        int id = 1;
        deleteStuInfo(id);
    }
    由于id=1的记录已经删除，再次调用删除方法，会报错
