我正在使用:

ehcache-1.6.0-beta3
ehcache-jm应用-0.3

我的Spring配置如下:

<bean id="cacheManager"
      class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
</bean>  
<bean id="cacheProvider"
      class="org.springmodules.cache.provider.ehcache.EhCacheFacade">
  <property name="cacheManager" ref="cacheManager" />
</bean>    
<ehcache:proxy id="pocDaoCache" refId="pocDao">
    <ehcache:caching methodName="fetch" cacheName="pocCache" />
</ehcache:proxy>

 <diskStore path="c:/projects/cache/demo" />

  <defaultCache maxElementsInMemory="50" eternal="false"
  timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" />


 <cache name="pocCache"
        maxElementsInMemory="10000"
        maxElementsOnDisk="1000"
        eternal="false"
        overflowToDisk="true"
        diskSpoolBufferSizeMB="20"
        timeToIdleSeconds="300"
        timeToLiveSeconds="600"
        memoryStoreEvictionPolicy="LFU"
        / >

 <cacheManagerPeerProviderFactory
             class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
             properties="initialContextFactoryName=JmsInitialContextFactory,
      userName=myuser,password=mypass,
                 providerURL=tcp://jmsdev1-jndi,tcp://jmsdev2-jndi
                 topicConnectionFactoryBindingName=TCF-00,
                 topicBindingName=MyTopiceName"
             propertySeparator=","
             />

   org.springframework.beans.factory.BeanCreationException:

 <cacheManagerPeerProviderFactory
        class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
        properties="initialContextFactoryName=com.InitialContextFactory;

    userName=uname;password=passwd;
            replicationTopicConnectionFactoryBindingName=TCF;
            replicationTopicBindingName=CACHE;
    providerURL=tcp://server1:7222,tcp://server2:7222;
    getQueueConnectionFactoryBindingName=QCF;
    getQueueBindingName=CACHE_LOAD
    "
    propertySeparator=";"
    />

另一件让我困惑的事情很简单,一旦我意识到这一点——你必须实现自己的密钥生成器,以确保Ehcache在每个JVM上保存具有相同密钥的对象。当你仔细想想,这是完全有道理的。

   <cacheLoaderFactory
        class="net.sf.ehcache.distribution.jms.JMSCacheLoaderFactory"
   properties="initialContextFactoryName=com.InitialContextFactory;

    userName=uname;password=passwd;
            replicationTopicConnectionFactoryBindingName=TCF;
            replicationTopicBindingName=CACHE;
    providerURL=tcp://server1:7222,tcp://server2:7222;
    getQueueConnectionFactoryBindingName=QCF;
    getQueueBindingName=CACHE_LOAD
    "
    propertySeparator=";"
    />

关于密钥生成问题,这实际上是一个已知的问题- MOD-255 。我们将把它修补到 Spring Modules Fork 很快。
