Spring3 + Hibernate4 报错?报错

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/applicationContext-hibernate.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

方言是有配置的：

<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>
<prop key="hiberante.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>
<prop key="hibernate.cache.use_second_level_cache">false</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.jdbc.fetch_size">50</prop>
<prop key="hibernate.jdbc.batch_size">50</prop>
           <prop key="hibernate.connection.autocommit">true</prop>
           <prop key="hibernate.connection.release_mode">auto</prop>
           <prop key="javax.persistence.validation.mode">none</prop>
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
</props>
</property>
<property name="packagesToScan">
<!-- 多个包用逗号分割 -->
<value>com.zz.wechat.persistence</value>
</property>
</bean>

说是sessionFactory的获取方式发生变化了，具体该怎么做呢？官方文档里也是狗屁的都没有说明
