1、預設方式載入hibernate.cfg.xml檔案，編寫hibernate的操作類，通過Configuration cfg = new Configuration().configure("hibernate-c3p0.cfg.xml");載入指定配置檔案，並建立SessionFactory

package utils;

import org.hibernate.Session;  
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
  
public class HibernateUtils {  
/* 
  *讀取Hibernate.cfg.xml檔案 
*/  
    private static SessionFactory factory;  
      
    static {
        try { 
            //讀取hibernate.cfg.xml檔案  
            Configuration cfg = new Configuration().configure("hibernate-c3p0.cfg.xml"); 
            //建立SessionFactory 
            ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(cfg.getProperties()).build();  
            factory = cfg.buildSessionFactory(serviceRegistry);
        }catch(Exception e) {  
            e.printStackTrace();  
        }  
    }  
    /* 
      *開啟Session 
    */  
      
    public static Session getSession() {  
        return factory.openSession();  
    }   
    /* 
      *關閉Session 
    */  
      
    public static void closeSession(Session session) {  
        if (session != null) {  
            if (session.isOpen()) {  
                session.close();  
            }  
        }  
    }  
      
    public static SessionFactory getSessionFactory() {  
        return factory;  
    }  
}
