此错是因为一时大意把hibernate.cfg.xml中关于二级缓存配置的属性名称写错了

<!-- 二级缓存配置 -->
  <!-- 1.导入commons-logging-1.1.3.jar架包 -->
  <!-- 2.将hibernate-distribution-3.3.2.GA\project\etc\ehcache.xml放置src下 -->
  <!-- 3.设置属性hibernate.cache.use_second_level_cache -->
  <property name="hibernate.cache.use_second_level_cache">true</property>
  <!-- 4.设置属性 hibernate.cache.provider_class -->
  <property name="hibernate.cache.provider_class">org.hibernate.catche.EhCacheProvider</property>
  <mapping class="com.nw.vo.Students" />
  <!-- 5.设置使用二级缓存的实体 -->
  <class-cache usage="read-only" class="com.nw.vo.Students" />

把第四步
  <property name="hibernate.cache.provider_class">写成了
  <property name="hibernate.catche.provider_class">

唉，掌握一门外语是多么滴可贵
