ehcache不在同一台機器上的兩個tomcat之間復制

Question

我正在嘗試在同一台計算機上的兩個tomcat之間設置緩存復制。 緩存工作正常，但復制無效。

為了進行測試，我在服務器1上調用了count方法。然后在服務器2上添加了一個實體，並在服務器2上調用了count方法。最后，我在服務器1上再次調用了count方法：緩存被命中，我添加的實體找不到。

Tomcat版本：6，Java版本：1.6，Ehcache版本：1.3，OS：Linux

啟動時登錄（兩台服務器相同）：

DEBUG net.sf.ehcache.store.MemoryStore - Initialized net.sf.ehcache.store.LruMemoryStore for myCacheSample
DEBUG net.sf.ehcache.store.LruMemoryStore - myCacheSample Cache: Using SpoolingLinkedHashMap implementation
DEBUG net.sf.ehcache.Cache - Initialised cache: myCacheSample
DEBUG net.sf.ehcache.distribution.RMICacheManagerPeerListener - Adding myCacheSample to RMI listener
DEBUG net.sf.ehcache.distribution.RMICacheManagerPeerListener - 0 RMICachePeers bound in registry for RMI listener

代碼添加：

public void persist(MyEntity myEntity) {
    getEntityManager().persist(myEntity);
}

具有緩存設置的代碼數：

public int count(String criteriaStr) {
    Criteria criteria = ((HibernateEntityManager) getEntityManager()).getSession().createCriteria(MyEntity.class);
    criteria.setCacheable(true).setCacheRegion("myCacheSample");
    criteria.add(Restrictions.eq("criteriaStr", criteriaStr));
    return (Integer) criteria.setProjection(Projections.rowCount()).uniqueResult();
}

刪除代碼：

public void remove(MyEntity myEntity) {
    getEntityManager().remove(myEntity);
    getEntityManager().flush();
}

服務器1 ehcache.xml（對於服務器2：端口40001和40002已切換）：

<cacheManagerPeerProviderFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
    properties="peerDiscovery=manual,
    rmiUrls=//localhost:40002/myCacheSample"/>

<cacheManagerPeerListenerFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
    properties="
    hostName=localhost,
    port=40001,
    socketTimeoutMillis=2000
"/>

<defaultCache
    diskExpiryThreadIntervalSeconds="120"
    diskPersistent="false"
    eternal="false"
    maxElementsInMemory="1000"
    memoryStoreEvictionPolicy="LRU"
    overflowToDisk="true"
    timeToIdleSeconds="120"
    timeToLiveSeconds="120">

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

<cache
    eternal="false"
    maxElementsInMemory="1000"
    timeToLiveSeconds="300"
    timeToIdleSeconds="300"
    name="myCacheSample"
    overflowToDisk="false"/>

謝謝您的解答！

3個tomcat實例的RMI復制的有效配置希望它對您有用。

    Server 1

<cacheManagerPeerProviderFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
    properties="peerDiscovery=manual, rmiUrls=//localhost:40002/apicache|//localhost:40003/apicache" />

<cacheManagerPeerListenerFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
    properties="hostName=192.168.1.152, port=40001, socketTimeoutMillis=2000" />

Server 2        

<cacheManagerPeerProviderFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
    properties="peerDiscovery=manual, rmiUrls=//localhost:40001/apicache|//localhost:40003/apicache" />

<cacheManagerPeerListenerFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
    properties="hostName=192.168.1.152, port=40002, socketTimeoutMillis=2000" />

Server 3

<cacheManagerPeerProviderFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
    properties="peerDiscovery=manual, rmiUrls=//localhost:40001/apicache|//localhost:40002/apicache" />

<cacheManagerPeerListenerFactory
    class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
    properties="hostName=192.168.1.152, port=40003, socketTimeoutMillis=2000" />
