Spring整合Hibernate

        Spring整合Hibernate，便是將Hibernate的SessionFactory交由Spring的IOC容器管理，同時也讓Hibernate使用上Spring的聲明式事務。

        須要如下配置：

　　 一、在Spring配置文件applicationContext.xml中添加sessionFactory的配置。

        二、配置聲明式事務管理

        Spring整合Hibernate能夠分別使用各自的配置文件也能夠直接在Spring配置文件中配置Hibernate,棄用Hibernate配置文件(hibernate.cfg.xml)
