spring和hibernate的另外一种整合方式：通过hibernate的配置文件来整合，这样要好的多：个人感觉

< bean  id ="sessionFactory"  class ="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" >   
    < property  name ="configLocation"  value ="classpath:hibernate.cfg.xml"   />
   
     </ bean >   

配置文件和以前一样在，src目录下，其实最后也到web-inf／class下面去了。这样hibernate的配置文件就不用写到spring的配置文件里了。挺好。
