终于解决了,分享：JMS Replicator实现Ehcache集群========

webwhs 2011-01-14 01:19:32

应用场景：ABC三台服务器使用ehcache缓存数据，其中A缓存数据发生变化，BC需同步A服务器的数据变化。

1. 建立openMQ链接

Topic链接建立

imqobjmgr add -t tf -l 'MyConnectionFactory'
　　　　　-j java.naming.provider.url=file:///tmp
　　　　　-j java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
　　　　　-f
imqobjmgr add -t t -l 'ehcache' -o 'imqDestinationName=EhcacheTopicDest'
　　　　　-j java.naming.provider.url=file:///tmp
　　　　　-j java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
　　　　　-f
Queue 链接建立
imqobjmgr add -t qf -l 'MyQueueConnectionFactory'
　　　　　-j java.naming.provider.url=file:///tmp
　　　　　-j java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
　　　　　-f
imqobjmgr add -t q -l 'queueEhcache' -o 'imqDestinationName=EhcacheQueueDest'
　　　　　-j java.naming.provider.url=file:///tmp
　　　　　-j java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
　　　　　-f
参考资料：进入mq目录，imqobjmgr -H
提示成功后，在c盘tmp下拿到 .bings文件（所有链接以来此文件）
2.配置ehcache xml文件
监听工厂配置
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory"
properties="
initialContextFactoryName=com.sun.jndi.fscontext.RefFSContextFactory,
userName=admin,password=admin,
replicationTopicConnectionFactoryBindingName=MyConnectionFactory,
replicationTopicBindingName=ehcache,
getQueueConnectionFactoryBindingName=MyQueueConnectionFactory,
getQueueBindingName=QueueEhcache, providerURL=file:C:/tmp"
propertySeparator="," />
缓存节点配置
<cache name="sampleCacheAsync" maxElementsInMemory="1000" eternal="false" timeToIdleSeconds="1000" timeToLiveSeconds="1000" overflowToDisk="false">
<cacheEventListenerFactory class="net.sf.ehcache.distribution.jms.JMSCacheReplicatorFactory" properties="replicateAsynchronously=true, replicatePuts=true, replicateUpdates=true, replicateUpdatesViaCopy=true, replicateRemovals=true, asynchronousReplicationIntervalMillis=1000" />
<cacheLoaderFactory class="net.sf.ehcache.distribution.jms.JMSCacheLoaderFactory" properties="initialContextFactoryName=com.sun.jndi.fscontext.RefFSContextFactory, providerURL=file:C:/tmp, replicationTopicConnectionFactoryBindingName=MyConnectionFactory, replicationTopicBindingName=ehcache, getQueueConnectionFactoryBindingName=MyQueueConnectionFactory, getQueueBindingName=QueueEhcache, timeoutMillis=10000, userName=admin, password=admin" propertySeparator="," />
</cache>
服务端测试类
import java.util.Timer;
import java.util.TimerTask;
import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Element;

public class EhCacheManager {
private static CacheManager cacheManager;

public static void main(String args[]){
cacheManager = new CacheManager();
Cache cache = EhCacheManager.getCacheObject("sampleCacheAsync");
if(cache != null){
System.out.println("load cache success!");
}
new EhCacheManager().start();
}

public static Cache getCacheObject(String objName){
if(cacheManager == null){
System.out.println("no init....... ");
}
return cacheManager.getCache(objName);
}

public void start(){
Timer timer = new Timer(false);
timer.schedule(new MasterListener(), 0, 10000);
}

public class MasterListener extends TimerTask {
@Override
public void run() {
printCache();
}
}

public static void printCache(){
Cache cache = EhCacheManager.getCacheObject("sampleCacheAsync");
if(cache != null){
Element element = cache.get("1234");
if(element != null){
System.out.println(element.getValue());
}else{
System.out.println("no element object");
}
}else
{
System.out.println("no cache object!");
}
cache.put(new Element("1234", "============"));
}
}
通过发送topic message 改变缓存
