Ehcache分布式缓存的最小化配置
注意:分布式配置依赖于ehcache-1.3.0.jar、backport-util-concurrent.jar包,ehcache必须是1.3以上。
配置ehcache作为分布式缓存,需要修改ehcache.xml,增加下面的内容:
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=automatic,
multicastGroupAddress=230.0.0.1,
multicastGroupPort=4446"/>
<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>
and then at least one cache declaration with
<cacheEventListenerFactory
class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>
in it. An example cache is:
<cache name="sampleDistributedCache1"
maxElementsInMemory="10"
eternal="false"
timeToIdleSeconds="100"
timeToLiveSeconds="100"
overflowToDisk="false">
<cacheEventListenerFactory
class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"/>
</cache>
Each server in the cluster can have the same config.
Ehcache API的用法:
Set set=new HashSet();
set.add("广州");
set.add("香港");net.sf.ehcache.CacheManager manager = new net.sf.ehcache.CacheManager();
Cache cache = manager.getCache("a");
Element element = new Element("key1", set);
cache.put(element);
Element element2 = cache.get("key1");
Serializable value = element2.getValue();
System.out.println("value:"+value);
