在配置hibernate缓存的时候出的错，我就把我这个缓存代码注释掉了。代码如下

[html] view plaincopy

1. <prop key="hibernate.cache.use_second_level_cache">false</prop><!-- 二级缓存 -->  
2. <prop key="hibernate.cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</prop>  
3.   
4. <!--   
5. <prop key="hibernate.cache.provider_class">com.opensymphony.oscache.hibernate.OSCacheProvider  
6.                 </prop>   
7. -->
