hibernateutils.java

这适合利用java开发Hibernate程序的初学者借鉴的代码

package com.hibernate;

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

public class HibernateUtils {
	private static SessionFactory factory;
	
	static {
			try{
			Configuration cfg = new Configuration().configure() ;
			factory = cfg.buildSessionFactory() ;
		}catch(Exception e)
		{
			e.printStackTrace() ;
		}
	}
	
	public static SessionFactory getSessionFactory(){
		return factory ;
	}
	
	public static Session openSession(){
		return factory.openSession() ;
	}
	
	public static void closeSession(Session session) {
		if(session != null ){
			if(session.isOpen()){
				session.close() ;
			}
		}
		
	}
}
