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>
