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
