org.hibernate.HibernateException: Не удалось создать экземпляр default tuplizer

Question

У меня возникла проблема при настройке моей первой программы спящего режима, но я застрял на последнем этапе процесса. Вот StackTrace:

мой конфигурационный файл спящего режима (hibernate.cfg.xml):

    </session-factory> 


</hibernate-configuration> 

и мой класс InsertStudent:

package edu.aspire.daos; 

import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.Transaction; 
import org.hibernate.cfg.Configuration; 

import edu.aspire.li.Student; 
//Insert Student object as student record into DataBase 
class InsertStudent { 
    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     Configuration cfg = new Configuration(); 
     cfg.configure("hibernate.cfg.xml"); 
     SessionFactory sf = cfg.buildSessionFactory(); 
     //Open Session 
     Session s = sf.openSession(); 
     //Begin transaction 
     Transaction tx=s.beginTransaction(); 

     //Create Student object 
     Student s1 = new Student(); 
     s1.setSno(1); 
     s1.setName("abc"); 
     s1.setEmail("abc@aspire.com"); 
     s1.setMobile(7788198899L); 

     s.save(s1); 
     s.flush(); 
     tx.commit(); 
     s.close();  
    } 
} 

Я поместил свой класс student, student.hbm.xml в edu.aspire.li, мой класс вставки ученика в edu.aspire.daos и мой hibernate.cfg.xml в пакет по умолчанию.

Заранее спасибо.

Answer 1

Спасибо за @ cpierceworld, я заявляю о своем студента, как

package edu.aspire.li; 

import java.io.Serializable; 

public class Student implements Serializable{ 
    private int sno; 
    private String name; 
    private String email; 
    private long mobile;  

    public Student(){ 
     System.out.println("This is to construct student"); 
    } 
    public int getSno() { 
     return sno; 
    } 
    public void setSno(int sno) { 
     this.sno = sno; 
    } 
    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public String getEmail() { 
     return email; 
    } 
    public void setEmail(String email) { 
     this.email = email; 
    } 
    public long getMobile() { 
     return mobile; 
    } 
    public void setMobile(long mobile) { 
     this.mobile = mobile; 
    } 


} 

Существует конфликт имен с student.hbm.xml

<property name ="sname" column="SNAME" type="string" length="100"/>
