使用TCP的Ehcache Jgroups复制

Question

我正在尝试使用ehcache.xml设置复制缓存。我在集群缓存时遇到了问题。我在eclipse中创建了两个项目，每个项目都引用了不同的ehcache.xml配置文件。

这两个配置文件都是相同的，并且都提供了beolw。

<?xml version="1.0"?>

​

<cacheManagerPeerProviderFactory
    class="net.sf.ehcache.distribution.jgroups.JGroupsCacheManagerPeerProviderFactory"
    properties="connect=TCP(bind_port=7800):
    TCPPING(initial_hosts=localhost[7800],localhost[7801];port_range=10;timeout=3000;
    num_initial_members=3):
    VERIFY_SUSPECT(timeout=1500):
    pbcast.NAKACK(retransmit_timeout=3000):
    pbcast.GMS(join_timeout=50000;print_local_addr=true)"
propertySeparator="::" />

 <cache name="sampleCache"
        maxElementsInMemory="1000000"
        eternal="true"
        overflowToDisk="false">
        <cacheEventListenerFactory
        class="net.sf.ehcache.distribution.jgroups.JGroupsCacheReplicatorFactory"
        properties="replicateAsynchronously=true"/>
</cache>

​

我在类路径中使用以下jar文件。

-ehcache-2.9.0.jar -ehcache-jgroupsreplication-1.7.jar -jgroups-3.6.0.Final.jar -log4j-1.2.16

当我运行程序时，project1显示

但是复制根本不会发生，我已经使用Ehcache做了RMIreplication，并遵循了同样的方法。因此，我假设我的java代码中没有任何错误。

我找不到配置错误的问题？？请帮助我解决此问题。I‘me find here.Is my configuration wrong？？请帮助我解决此问题。

您使用的配置很奇怪:它与某些协议不匹配。ehcache不能引用JGroups配置文件吗，例如udp.xml？您还可以在TCP中设置bind_addr或使用-Djgroups.bind_addr=1.2.3.4，其中1.2.3.4是网络接口。然后，在TCPPING.initial_hosts中，您需要列出具有上面使用的绑定地址的所有成员，例如1.2.3.47800、5.6.7.87800等。
