Question

我正在尝试使用JMS复制实现带有ehcache的hibernate集群二级缓存。 Hibernate版本是3.6.10.final，spring版本是3.2.2。

当servlet启动时，我收到以下错误：

我的ehcache.xml是：

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="true" monitoring="autodetect" dynamicConfig="true">

   <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
properties="initialContextFactoryName=com.targa.fleetGateway.ExampleActiveMQInitialContextFactory, 
providerURL=tcp://127.0.0.1:61616,   replicationTopicConnectionFactoryBindingName=topicConnectionFactory, 
replicationTopicBindingName=ehcache, getQueueConnectionFactoryBindingName=queueConnectionFactory, getQueueBindingName=ehcacheGetQueue,  topicConnectionFactoryBindingName=topicConnectionFactory,  topicBindingName=ehcache" 
propertySeparator="," />

   <defaultCache 
maxElementsInMemory="100" 
eternal="false" 
timeToIdleSeconds="300" 
timeToLiveSeconds="600" 
overflowToDisk="false">

      <cacheEventListenerFactory class="net.sf.ehcache.distribution.jms.JMSCacheReplicatorFactory" 
properties="replicateAsynchronously=true, replicatePuts=true, replicateUpdates=true, 
replicateUpdatesViaCopy=true, replicateRemovals=true, asynchronousReplicationIntervalMillis=1000" 
propertySeparator="," />

      <cacheLoaderFactory class="net.sf.ehcache.distribution.jms.JMSCacheLoaderFactory"
properties="initialContextFactoryName=com.targa.fleetGateway.ExampleActiveMQInitialContextFactory, 
providerURL=tcp://127.0.0.1:61616,   replicationTopicConnectionFactoryBindingName=topicConnectionFactory,
getQueueConnectionFactoryBindingName=queueConnectionFactory,   replicationTopicBindingName=ehcache,   
getQueueBindingName=ehcacheGetQueue,  timeoutMillis=10000" />

   </defaultCache>

</ehcache>

如果我注释掉cacheLoaderFactory部分，事情就会重新开始。相同的配置适用于我使用hibernate 4.2的另一个应用程序，但我无法升级到4.2。

有人对此有任何疑问吗？

以下是我配置的其他相关部分。如果有任何遗漏，请告诉我。

我今天遇到了这个问题：原因是defaultCache不应该有：cacheLoaderFactory。奇怪的是它没有在文档中提到（所以我从defaultCache中删除了cacheLoaderFactory - 一切正常;

Ehcache，具有JMS复制和activemq的CacheException
