WebLogic群集中的EhCache rmi复制问题

Question

在将应用程序部署到WebLogic 10.3.6时，我正面临ehcache复制问题。 应用程序没有启动，并抛出以下异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ehCacheManager' defined in class path resource [xxxxx.xml]: Invocation of init method failed; nested exception is net.sf.ehcache.CacheException: Problem starting listener for RMICachePeer //xxxx:xxxx/myCache. Initial cause was RemoteException occurred in server thread; nested exception is: 
    java.rmi.AccessException: Registry.Registry.rebind disallowed; origin /x.x.x.x is non-local host 
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1455) 
    ... 

Caused by: net.sf.ehcache.CacheException: Problem starting listener for RMICachePeer //xxxx:xxxx/myCache. Initial cause was RemoteException occurred in server thread; nested exception is:

    at org.springframework.cache.ehcache.EhCacheManagerFactoryBean.afterPropertiesSet(EhCacheManagerFactoryBean.java:104) 
    ... 

的Ehcache配置如下：

<diskStore path="java.io.tmpdir/myCache" /> 

<cacheManagerPeerProviderFactory 
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" 
    properties="peerDiscovery=manual,rmiUrls=//x.x.x.x:xxxx/myCache" />        

<cacheManagerPeerListenerFactory 
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" 
    properties="hostName=x.x.x.x,port=xxxx,socketTimeoutMillis=300000" /> 

<cache 
    name="myCache" 
    maxElementsInMemory="1000" 
    eternal="false" 
    overflowToDisk="false" 
    diskPersistent="false" 
    timeToIdleSeconds="0" 
    timeToLiveSeconds="1000" 
    memoryStoreEvictionPolicy="LRU"> 
    <cacheEventListenerFactory 
     class="net.sf.ehcache.distribution.RMICacheReplicatorFactory" 
     properties="replicatePuts=true,replicateUpdates=true,replicateRemovals=true,replicateUpdatesViaCopy=true,replicateAsynchronously=true" /> 
    <bootstrapCacheLoaderFactory 
     class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory" /> 
</cache> 

得到任何帮助。

我可以通过将缓存发现策略更改为自动和多播来使其工作。

见工作结构如下：

<cacheManagerPeerProviderFactory 
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" 
    properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1,  
    multicastGroupPort=4447, timeToLive=32" /> 

<cacheManagerPeerListenerFactory 
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" 
    properties="port=xxxx,socketTimeoutMillis=300000" /> 

<cache 
    name="myCache" 
    maxElementsInMemory="1000" 
    eternal="false" 
    overflowToDisk="false" 
    diskPersistent="false" 
    timeToIdleSeconds="0" 
    timeToLiveSeconds="1000" 
    memoryStoreEvictionPolicy="LRU"> 
    <cacheEventListenerFactory 
     class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/> 
    <bootstrapCacheLoaderFactory 
     class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"/> 
</cache>
