Myeclipse下使用Hibernate的小程序

package com.pyf.test2;

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

import com.pyf.test.*;

public class Test1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        // 必须加入事务
        User user = new User(5,"aa",5);
        
        UserDAO userdao = new UserDAO();
        /*
        Session session = HibernateSessionFactory.getSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
        session.close();
        */
        //必须加入事务
        Transaction ts = userdao.getSession().beginTransaction();
        userdao.save(user);
        ts.commit();
        userdao.getSession().close();
        
    }

}
