SSH集成项目，使用注解方式，竟然还有这样的问题！！

在applicationContext.xml文件中，配置了hibernate的相关信息，其中SessionFactory是这样的

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.Oracle9Dialect
                </prop>
            </props>
        </property>
        <property name="packagesToScan">
            <list>
                <value>cn.jbit.pb.tcjc034.shop.entity</value>
            </list>
        </property>
    </bean>

但是如果是这样

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.Oracle9Dialect
                </prop>
            </props>
        </property>
        <property name="packagesToScan">
            <list>
                <value>
                    cn.jbit.pb.tcjc034.shop.entity
                </value>
            </list>
        </property>
    </bean>

就会找不到实体，异常信息如下：
