hibernate4缓存org.hibernate.cache.NoCacheRegionFactoryAvailableException

在配置hibernate4的二级缓存时，启动报错
org.hibernate.cache.NoCacheRegionFactoryAvailableException

下面是我在hibernate.cfg.xml中的配置

  <!-- 开启二级缓存 -->    <property                                                                      name="hibernate.cache.use_second_level_cache">true  </property>    <!-- 设置二级缓存插件EHCache的Provider类-->   <property name="hibernate.cache.provider_class">       org.hibernate.cache.EhCacheProvider    </property>    <property  name="cache.use_query_cache">  true  </property>

已经导入了hibernate文件夹中ehcache需要的所有jar
后来百度后发现，在hibernate.cfg.xml配置有错误，在hibernate4中，设置二级缓存的配置已经不再是上面的配置，上面用到的还是hibernate3的，正确配置应该是

 <!-- 开启二级缓存 -->        <property                      name="hibernate.cache.use_second_level_cache">true</property>        <!-- 设置二级缓存插件EHCache的Provider类-->        <property              name="hibernate.cache.region.factory_class">      org.hibernate.cache.ehcache.EhCacheRegionFactory      </property>
