为了集成spring和hibernate，我将sessionFactory bean添加到applicationContext.xml中 .

在Intitally我使用 org.springframework.orm.hibernate3.LocalSessionFactoryBean 并将映射资源作为test.hbm.xml文件 .

现在我想使用带注释的实体类作为映射资源 . 为此，我已将sessionFactory类更改为 org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean .

applicationContext.xml

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

<property name="dataSource" ref="dataSource"/>

<property name="annotatedClasses">
   <list>
       <value>org.droidaceapps.contractortimeflow.User</value>           
   </list>
</property>


<property name="hibernateProperties">
  <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
    <prop key="hibernate.hbm2ddl.auto">update</prop>        
  </props>
</property>

但Tomcat抛出以下异常，

我错过了什么？

谢谢
