解决方案：

将spring 的配置文件 装配 sessionFactory的地方的class

org.springframework.orm.hibernate3.LocalSessionFactoryBean

改成

org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean

检查Spring中sessionFactory中是否引进了hibernate文件

	<bean id="sessionFactory"

		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

		<property name="configLocation" value="classpath:hibernate.cfg.xml">

		</property>

	</bean>
