一、前言

关于hibernate-util源码包中net.sf.gilead.core.hibernate.jboss.HibernateJBossUtil、net.sf.gilead.core.hibernate.jpa.HibernateJpaUtil、net.sf.gilead.core.hibernate.spring.HibernateSpringUtil三个工具类，分别注入jboss、jpa、spring容器实现的org.hibernate.SessionFactory会话工厂对象，详情参见源码说明。

二、源码说明

三个HibernateJBossUtil、HibernateJpaUtil、HibernateSpringUtil工具类（继承net.sf.gilead.core.hibernate.HibernateUtil基类）
