[转载]Ehcache配置

环境搭建
将ehcache-2.1.0-distribution.tar.gz解压
需要将它们放置到WEB-INF/lib 下。
有一个重要的配置文件ehcache.xml，可以从ehcache 组件包中拷贝一个，也可以自
己建立一个。需要放到classpath 下。常放的路径为/WEB-INF/classes/ehcache.xml

ehcache.xml

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="ehcache.xsd">
    <cacheManagerPeerProviderFactory
        class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
        properties="peerDiscovery=manual,
        rmiUrls=//127.0.0.1:57651/paramCache" />

    <cacheManagerPeerListenerFactory
        class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
        properties="hostName=127.0.0.1,port=57651,socketTimeoutMillis=120000" />

    
    <defaultCache maxElementsInMemory="10000" eternal="true"
        timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true"
        diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000"
        diskPersistent="false" diskExpiryThreadIntervalSeconds="120"
        memoryStoreEvictionPolicy="LRU">
        <cacheEventListenerFactory
            class="net.sf.ehcache.distribution.RMICacheReplicatorFactory" />
    </defaultCache>

    <cache name="paramCache" maxElementsInMemory="10000" eternal="true"
        timeToIdleSeconds="100000" timeToLiveSeconds="100000"
        overflowToDisk="true">
        <cacheEventListenerFactory
            class="net.sf.ehcache.distribution.RMICacheReplicatorFactory" />
    </cache>
</ehcache>
