1.首先,在spring的hibernate配置里(我的是applicationContext-hibernate.xml) 加上如下屬性:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">         
  <property name="dataSource">
   <ref bean="dataSource"/>
  </property>
  <property name="mappingResources">
   <list>
    <value>org/appfteaching/model/TArticleclass.hbm.xml</value>
   </list>
  </property>
  <property name="hibernateProperties">
   <props>
    <prop key="hibernate.dialect">${hibernate.dialect}</prop>
          <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
          <prop key="hibernate.jdbc.fetch_size">${hibernate.jdbc.fetch_size}</prop>
          <prop key="hibernate.jdbc.batch_size">${hibernate.jdbc.batch_size}</prop>
          <prop key="hibernate.cache.use_query_cache">true</prop>
          <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
   </props>   
  </property>  
 </bean> 

2.其次,在src目錄下的ehcache.xml中配置如下信息(如果是默認ehcache.xml則會有<cache name="sampleCache1">和<cache name="sampleCache2>",去掉)

<cache name="org.hibernate.cache.StandardQueryCache"
        maxElementsInMemory="10000"
        eternal="false"
        timeToIdleSeconds="300"
        timeToLiveSeconds="4200"
        overflowToDisk="true"
        />

    <!-- Sample cache named sampleCache2
        This cache contains 1000 elements. Elements will always be held in memory.
        They are not expired. -->

    <cache name="org.hibernate.cache.UpdateTimestampsCache"
        maxElementsInMemory="5000"
        eternal="true"
        timeToIdleSeconds="0"
        timeToLiveSeconds="0"
        overflowToDisk="false"
        />

3.將你要緩存的model加進ehcache.xml里

<cache name="org.appfteaching.model.TArticleclass"
     maxElementsInMemory="1000"
        eternal="false"
        timeToIdleSeconds="100"
        timeToLiveSeconds="4200"
        overflowToDisk="true"
     />  

4.最后一步,在TArticleclass.hbm.xml里加上

<cache usage="read-write"/>

啟動Tomcat,如發現如下錯誤

Could not find configuration [org.hibernate.cache.UpdateTimestampsCache]; using defaults.
Could not find configuration [org.hibernate.cache.StandardQueryCache]; using defaults.

則是第二步沒有做,加上即可.配置完畢
