配置

Ehcache Maven

            <artifactId>cas-server-integration-ehcache</artifactId>

            <version>${project.version}</version>

            <scope>compile</scope>

        </dependency>

        <dependency>

            <artifactId>ehcache</artifactId>

            <version>2.10.1</version>

        </dependency>

Ehcache配置文件ehcache-replicated.xml

节点a（以端口8433为例）

  <ehcache name="ehCacheTicketRegistryCache"

   updateCheck="false"

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">

  <diskStore path="java.io.tmpdir/cas"/>

          properties="port=41001,remoteObjectPort=41002" />

  -->

  <cacheManagerPeerProviderFactory

          class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"

          properties="peerDiscovery=manual,rmiUrls=//127.0.0.1:41041/cas_st|//127.0.0.1:41041/cas_tgt" />

  <cacheManagerPeerListenerFactory

          class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"

          properties="port=41031, remoteObjectPort=41032" />

  </ehcache>

节点b（以端口8443为例）

   <cacheManagerPeerProviderFactory

          class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"

          properties="peerDiscovery=manual,rmiUrls=//127.0.0.1:41031/cas_st|//127.0.0.1:41031/cas_tgt" />

  <cacheManagerPeerListenerFactory

          class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"

          properties="port=41041,remoteObjectPort=41042" />

注意以上ProviderFactory和ListenerFactory中的给出的端口：

ListenerFactory是指定本地Cache节点的端口
ProviderFactory是配置远程Cache节点的端口
如果二个以上节点，则所有节点都要列出并用 | 符号分隔

Ehcache在CAS TicketRegistry.xml 中的配置
