tips:
transporttransport
这里是将transportclass指定为JGroupsTransport，这里的transport必须是org.infinispan.remoting.transport.Transport的子类，infinispan自己仅仅实现了jgroups的transport,如果不想用jgroups的话，那么自己基于socket实现一个transport也是可以的。
clusterName="infinispan-cluster"
这里指定cluster name,只有在同一个cluster内部的节点才能互相复制数据。
nodeName="ClusterTest"
nodeName在默认情况下可以不写
<property name="configurationFile"value="stacks/tcp.xml"/>
这个属性很重要，表示stacks的配置信息是从statcks/tcp.xml里读取，注意，对应的name一定要设置成configurationFile。当然也可以使用编程的方式来指定，这里总共可以有四种方式，具体配置和代码可以参考infinispan的官方文档。


default的这一段是对cache做一些通用的配置，其中需要注意的是clusteringmode="r"，mode有三种模式，local,replication anddistribution,如果不写模式的话，默认就是local,r和d分别是replication以及distribution的简写。
在infinispan里我们可以使用jpa或者jta的transactionmanager来管理事务，如果是测试环境下，则可以使用dummy transactionmanager(infinispan自己提供的，只是如果需要跟spring一起用的话，需要将这个transactionmanager作为spring中jta transaction manager的构造函数参数注入)

expirationlifespan="5000"也很重要，它规定了多长时间缓存的对象过期。当然这也可以在cache层面用编码的方式来指定。

jgroups的基本配置
使用tcp

tips:
大部分情况下tcp/udp的配置没有这么复杂，这两个是最复杂的例子，如果自己配置的话
