spring 配置文件 ，配置了一个  映射映射文件，有点不是很明白。这不是hibernate配置文件吗？spring中怎么又也要用到hibernate？

 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
  <property name="dataSource"  ref="dataSource"/>
  <property name="hibernateProperties">
  <props>
  <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
  <prop key="hibernate.show_sql" >true</prop>
  <prop key="hibernate.format_sql" >true</prop>
  <prop key="hibernate.hbm2ddl.auto">update</prop>
   </props>
   </property>
    <property name="mappingResources">
   <list>
    <value>user.xml</value>
   </list>
   </property> 
  </bean>
