hibernateutil.java

这是一个jbpm的高级应用,是一个oa工作流的系统,里面用到了spring,hibernate技术等.实为学习jbpm的好资料!

package com.xiangfeng.util.hibernateUtil;

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

public class HibernateUtil {
	
	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 getSession(){
		return factory.openSession();
	}
	
	public static void closeSession(Session session){
		if(session.isOpen()){
			session.close();
		}
	}
}
