使用TCP的Ehcache Jgroups复制

Question

我试图在Ehcache中使用Jgroups设置一个复制的缓存。我在集群缓存时遇到了问题。我在eclipse中创建了两个项目，每个项目引用不同的ehcache.xml配置文件。

这两个配置文件都是相同的，并且都给出了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>

我无法在这里找到问题。是我的配置错误吗？？请帮助我解决这个问题…

您使用的配置很奇怪：它遗漏了一些协议。ehcache不能引用JGroups配置文件，例如udp.xml吗？另外，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，需要列出具有上面使用的绑定地址的所有成员，例如1.2.3.4[7800]、5.6.7.8[7800]等。
