我正在尝试使用Ehcache中的Jgroups设置复制缓存。我在缓存集群时遇到问题。我在eclipse中创建了2个项目,每个项目都引用了不同的ehcache.xml配置文件。
两个配置文件都是相同的,并且给出了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

但是复制根本就没有发生。我已经使用Ehcache完成了RMIreplication,并且也遵循相同的方法。所以我假设我的java代码没有任何问题。
我无法在这里找到问题。我的配置错了吗?请帮我解决这个问题..
答案 0 :(得分:2)
您使用的配置很奇怪:它正在修改某些协议。 Can&#thhcache可以引用JGroups配置文件,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,您需要列出具有您在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。
