Ehcache集群

Ehcache集群的两种方式：组播方式和点对点方式

一、   组播方式

1)    配置cacheManagerPeerProviderFactory<cacheManagerPeerProviderFactoryclass="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"properties="peerDiscovery=automatic,multicastGroupAddress=230.0.0.2,multicast      groupPort=4447,timeToLive=1”propertySeparator=","                                        />            作用：当缓存发生变化，进行广播            属性： peerDiscovery：atutomatic为自动；multicastGroupAddress：广播组地址，指定D类IP地址空间，范围从 224.0.1.0 到 238.255.255.255 中的任何一个地址                     mulicastGroupPort广播组端口                     timeToLive：搜索范围0是同一台服务器1是同一个子网32是指同一站点64是指同一块地域128是同一块大陆256是任何  2)    配置cacheManagerPeerListenerFactory<cacheManagerPeerListenerFactory       class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"              />            作用：监听本服务器所有端口二、   点对点方式1)    配置cacheManagerPeerProviderFactory<cacheManagerPeerProviderFactory       class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"properties="peerDiscovery=manual,rmiUrls=//192.168.4.50:40002/com.pccw.kernel.dic.vo.ArchDicKindVOImpl|//192.168.4.50:40002/com.pccw.kernel.dic.vo.ArchDicItemVOImpl"/>作用：当缓存发生变化，通知集群中其他节点。属性： peerDiscovery：manual为手动      rmiUrls：通知需要同步的缓存3)    配置cacheManagerPeerListenerFactory<cacheManagerPeerListenerFactory       class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"properties="hostName=192.168.4.24,port=40001,socketTimeoutMillis=2000"              />              作用：监听本服务器指定端口  缓存的配置（共同部分） 

cacheEventListenerFactory：注册相应的的缓存监听类，用于处理缓存事件，如put,remove,update,和expire
bootstrapCacheLoaderFactory:指定相应的BootstrapCacheLoader，用于  在初始化缓存（从硬盘读取，overflowToDisk为false时，此配置失效），以及自动设置。

p2p方式
