  <bean id="hibernateMappingManager" init-method="init"     class="net.ondev.config.hibernate.HibernateMappingManager" />   <bean id="sessionFactory"     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">     <property name="mappingResources">            <bean           class="org.springframework.beans.factory.config.PropertyPathFactoryBean">           <property name="targetObject" ref="hibernateMappingManager" />           <property name="propertyPath" value="mappingFiles" />         </bean>     </property>   </bean>
在上面的例子中，sessionFactory的mappingResources属性是一个字符串数组类型的属性，熟悉Spring和hibernate的朋友知道这是所有映射文件的列表。而我们定义的hibernateMappingManager中，有一个名为mappingFiles的属性是所有这些文件的列表。通过使用PropertyPathFactoryBean我们成功地将mappingFiles注入到了sessionFactory的mappingResources属性
