Java Ehcache配置问题（密钥****的元素为空）

我对Ehcache配置有一个大问题

我使用：

• ehcache 2.6.2
• hibernate 3.3.1 GA

我当前的配置是：

1） 冬眠

<bean id="hibernateProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> 
  <property name="properties">
    <props> 
       <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> 
       <prop key="hibernate.default_schema">@db.schema@</prop> 
       <prop key="hibernate.show_sql">false</prop> 
       <prop key="connection.pool_size">10</prop> 
       <prop key="hibernate.jdbc.batch_size">30</prop> 
       <prop key="hibernate.default_batch_fetch_size">30</prop> 
       <prop key="hibernate.max_fetch_depth">30</prop> 
       <prop key="hibernate.cache.use_second_level_cache">true</prop> 
       <prop key="hibernate.cache.use_query_cache">true</prop> 
       <prop key="hibernate.cache.region.factory_class"> 
          net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory 
       </prop> 
       <prop key="net.sf.ehcache.configurationResourceName"> 
         /ehcache-config.xml 
       </prop> 
       <prop key="hibernate.generate_statistics">true</prop> 
     </props> 
  </property> 
</bean> 

我注意到的最重要的一点是：所有使用缓存的尝试都以以下方式结束：

 1) 19:30:47,396 DEBUG [EhcacheGeneralDataRegion] Element for key sql: **** is null

 2) 20:26:31,939 DEBUG [EhcacheGeneralDataRegion] key: ****
    20:26:31,939 DEBUG [EhcacheGeneralDataRegion] Element for key **** is null 

谢谢你的帮助

向您致意。

您能在每次命中对象时观察到

ehcache.getLiveCacheStatistics（）.getInMemoryHitCount（）

吗？它变了吗？
