Spring and Hibernate adjust traps when auto-scan

Spring and hibernate integrate automatic scanning traps
The spring 2.5.6 automatic package scanning (Packagestoscan) feature is used when configuring Hibernate+spring.

This feature automatically scans the entity classes in the package to avoid the hassle of writing annotatedclasses. But when I use this feature, I've been encountering errors like this:

caused By:org.hibernate.MappingException:Unknown entity:com.mycompany.app.model.Users

The configuration in spring is:

Java code    <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" >                    ${hibernate.dialect}                </prop>                <prop key= "HibernaTe.show_sql ">                    ${hibernate.show_sql}                </prop>                <prop key= "Hibernate.jdbc.fetch_size" >                    ${hibernate.jdbc.fetch_size}                </prop>                <prop key= "Hibernate.jdbc.batch_size" >                   ${ hibernate.jdbc.batch_size}                </prop>                <prop key= "Hibernate.c3p0.timeout" >                    ${hibernate.c3p0.timeout}                </prop>           </props>       </property>       <span style= " background-color:  #ff0000; " ><property name= "Packagestoscan"  value= "com.mycompany.app.model.*"  /></span>    </bean>  

But my entity class is clearly under Com.mycompany.app.model, why can't I scan it?

After a closer look at the document discovery, Packagestoscan's value should be configured as com.mycompany.app.*, which is the upper layer of the entity's package. This is really an incredible trap.
