ehcache缓存

ehcache缓存

spring配置文件中关键（非关联hibernate集成）

<!-- 设置ehcache缓存开始 -->
 <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
  <property name="configLocation">
   <value>classpath:ehcache.xml</value>
  </property>
 </bean>
 <!-- 设置ehcacheFactory -->
 <bean id="levelOneCache" class="org.springframework.cache.ehcache.EhCacheFactoryBean">
         <property name="cacheManager">
             <ref local="cacheManager" />
         </property>
        <property name="cacheName">
            <value>configCache</value>
        </property>
 </bean>
