Memcached配置文档

1、一 Memcached服务端的安装：1. 将memcached-1.2.1-win32.zip(也可以下载），解压放某个盘下面，比如在c:memcached2. 在终端（也即cmd命令界面）下输入 c:memcachedmemcached.exe -d install 安装memcached成为服务，这样才能正常运行，否则运行失败！3. 再输入： c:memcachedmemcached.exe -d start 启动memcached的。二 Memcached客户端的安装1.解压java_memcached-release_2.0.1.zip，将里面的java_memcached-relea

2、se_2.0.1.jar拷贝到WEB_INF/lib中2.在src目录下新建一个dhcache.xml文件，内容如下： <ehcache><diskStore path="java.io.tmpdir" /><defaultCache name="default" maxElementsInMemory="300" eternal="false" timeToIdleSeconds="500" timeToLiveSeconds="500" ov

3、erflowToDisk="true" diskPersistent="false" diskExpiryThreadIntervalSeconds="110" /><cache name="org.taha.cache.LOCAL_CACHE" maxElementsInMemory="300" eternal="false" timeToIdleSeconds="500" timeToLiveSeconds="500"

4、overflowToDisk="true" /> </ehcache>3.创建一个类，用来封装memcache的各种操作(连接，添加，删除，关闭等)public class CacheServiceprivate Cache localCache;String cacheServerList;String cacheServerWeights;boolean cacheCluster = false;int initialConnections = 10;int minSpareConnections = 5;int maxSpareConnections

5、 = 50;long maxIdleTime = 1000 * 60 * 30; / 30 minutes long maxBusyTime = 1000 * 60 * 5; / 5 minutes long maintThreadSleep = 1000 * 5; / 5 seconds int socketTimeOut = 1000 * 3; / 3 seconds to block on reads int socketConnectTO = 1000 * 3; / 3 seconds to block on initial boolean failover = false; / tu

6、rn off auto-failover in event of server / down boolean nagleAlg = false; / turn off Nagle's algorithm on all sockets in / pool MemCachedClient mc;public CacheService()mc = new MemCachedClient();mc.setCompressEnable(false);public void setLocalCache(Cache localCache)this.localCache = localCache;pu

7、blic void setCacheServerList(String cacheServerList)this.cacheServerList = cacheServerList;public void setCacheServerWeights(String cacheServerWeights)this.cacheServerWeights = cacheServerWeights;public void setCacheCluster(boolean cacheCluster)this.cacheCluster = cacheCluster;/* * 放入 * */public voi

8、d put(String key, Object obj)if (this.cacheCluster)mc.set(key, obj); elseElement element = new Element(key, (Serializable) obj);localCache.put(element);/* * 删除 */public void remove(String key)if (this.cacheCluster)mc.delete(key); elselocalCache.remove(key);/* * 得到 */public Object get(String key)Obje

9、ct rt = null;if (this.cacheCluster)rt = mc.get(key); elseElement element = null;tryelement = localCache.get(key); catch (CacheException cacheException)throw new DataRetrievalFailureException("Cache failure: "+ cacheException.getMessage();if (element != null)rt = element.getValue();return r

10、t;/* * 判断是否存在 * */public boolean exist(String key)if (this.cacheCluster)return mc.keyExists(key); elsereturn this.localCache.isKeyInCache(key);private void init()if (this.cacheCluster)String serverlist = cacheServerList.split(",");/Integer weights = this.split(cacheServerWeights); String t

11、emps = cacheServerWeights.split(",");Integer weights = new Integertemps.length;for (int t = 0; t < temps.length; t+)weightst = new Integer(tempst);/ initialize the pool for memcache servers SockIOPool pool = SockIOPool.getInstance();pool.setServers(serverlist);pool.setWeights(weights);p

12、ool.setInitConn(initialConnections);pool.setMinConn(minSpareConnections);pool.setMaxConn(maxSpareConnections);pool.setMaxIdle(maxIdleTime);pool.setMaxBusyTime(maxBusyTime);pool.setMaintSleep(maintThreadSleep);pool.setSocketTO(socketTimeOut);pool.setSocketConnectTO(socketConnectTO);pool.setNagle(nagl

13、eAlg);pool.setHashingAlg(SockIOPool.NEW_COMPAT_HASH);pool.initialize();private void destory()if (this.cacheCluster)SockIOPool.getInstance().shutDown();4.Spring配置文件中配置memcache<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"><prop
