在Tomcat群集中使用ehcache进行缓存复制

我为3个不同的tomcat实例提供以下ehcache配置。

我的假设是，在每个ehcache中，我们都应将所有其他节点定义为提供者，并将当前节点定义为侦听器。

是否应该在每个ehcache.xml中定义所有缓存？如果是，是否还要将这些名称添加到RMI地址中？我这样定义了ehcache。其中两个缓存的复制工作正常，但其他两个缓存的复制则不起作用（activityCache和classificationCache）。当然，它应该取决于它们的实现，但是在此时，我想确保ehcache配置正确。

这也是缓存和cahchSevices的定义：

        <property name="maxElementsInMemory" value="${cache.feature.maxMemoryElements}"/>
        <property name="maxElementsOnDisk" value="${cache.feature.maxDiskElements}"/> 
        <property name="overflowToDisk" value="${cache.feature.useDisk}"/>
      </bean>

      <bean id="featureCacheService" parent="abstractService" class="com.service.business.cache.impl.ehcache.EHcacheFeatureCacheService">

      </bean>

我将根据您的要求提供更多信息。

先感谢您。
