java 通过hibernate 访问数据库例子

package com.tc.test;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.Transaction;

import com.tc.db.HibernateSessionFactory;
import com.tc.model.TUser;

public class HibernateTest {

	public static void main(String[] args) {
		Session session= HibernateSessionFactory.currentSession();
		Transaction tran= session.beginTransaction();
		TUser user=(TUser)session.get(TUser.class,new Integer(2));
		session.delete(user);
		tran.commit();
		//----------edit------------
//		Transaction tran= session.beginTransaction();
//		TUser user=(TUser)session.get(TUser.class,new Integer(2));
//		user.setName("mike");
//		session.save(user);
//		tran.commit();
		//-----------add--------------
//		Transaction tran= session.beginTransaction();
//		TUser user=new TUser();
//		user.setName("tom");
//		user.setAge(new Integer(23));
//		user.setSex("man");
//		session.save(user);
//		tran.commit();
		//---------select---------------
//		String hql="from com.tc.model.TUser where name='tom'";
//		List l=session.createQuery(hql).list();
//		for (int i = 0; i < l.size(); i++) {
//			TUser user=(TUser)l.get(i);
//			System.out.println(user.getId().toString()+" "+user.getName()+" "+user.getSex());
//		}
	}
