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。
