windows 上memcached初步使用-java版

参考：http://q.sohu.com/forum/5/topic/640252
http://danga.com/memcached/
http://code.jellycan.com/memcached/
1.下载: memcached的Windows版本和java客户端 （从http://code.jellycan.com/memcached/下载Older Version)
memcached-1.2.1-win32.zip和java_memcached-release_1.6.zip
2. 解压:memcached-1.2.1-win32.zip 后 进入memcached.exe目录 ，运行下面命令安装启动memcached服务
eg:
c:>memcached.exe -d install
c:>memcached.exe -l 127.0.0.1 -m 32 -d start
执行完后，任务管理器会出现memcached进程
解压java_memcached-release_1.6.zip 将java_memcached-release_1.6.jar加入java项目的库中。

3. 一个简单的应用例子：

package test.cmei.memcached;
import java.util.Date;
import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;
public class MemCachedTest {// 创建全局的唯一实例
protected static MemCachedClient mcc = new MemCachedClient();protected static MemCachedTest MemCachedTest = new MemCachedTest();// 设置与缓存服务器的连接池
static {// 服务器列表和其权重
String[] servers = {"127.0.0.1:11211"};Integer[] weights = {3};// 获取socke连接池的实例对象
SockIOPool pool = SockIOPool.getInstance();// 设置服务器信息
pool.setServers( servers );pool.setWeights( weights );// 设置初始连接数、最小和最大连接数以及最大处理时间
pool.setInitConn( 5 );pool.setMinConn( 5 );pool.setMaxConn( 250 );pool.setMaxIdle( 1000 * 60 * 60 * 6 );// 设置主线程的睡眠时间
pool.setMaintSleep( 30 );// 设置TCP的参数，连接超时等
pool.setNagle( false );pool.setSocketTO( 3000 );pool.setSocketConnectTO( 0 );// 初始化连接池
pool.initialize();// 压缩设置，超过指定大小（单位为K）的数据都会被压缩
mcc.setCompressEnable( true );mcc.setCompressThreshold( 64 * 1024 );}/*** 保护型构造方法，不允许实例化！**/
protected MemCachedTest(){}/*** 获取唯一实例.* @return
*/
public static MemCachedTest getInstance(){return MemCachedTest;}/*** 添加一个指定的值到缓存中.* @param key* @param value* @return
*/
public boolean add(String key, Object value){return mcc.add(key, value);}public boolean add(String key, Object value, Date expiry){return mcc.add(key, value, expiry);}public boolean replace(String key, Object value){return mcc.replace(key, value);}public boolean replace(String key, Object value, Date expiry){return mcc.replace(key, value, expiry);}/*** 根据指定的关键字获取对象.* @param key* @return
*/
public Object get(String key){return mcc.get(key);}public static void main(String[] args){MemCachedTest cache = MemCachedTest.getInstance();cache.add("hello1", 234);System.out.print("hello : " + cache.get("hello1"));TBean tb = new TBean();tb.setName("name");cache.add("bean", tb);TBean tb1 = (TBean)cache.get("bean");System.out.print("name=" + tb1.getName());tb1.setName("name2");tb.setName("name3");// cache.replace("bean", tb);
System.out.println("tb1:name=" + tb1.getName());System.out.println("tb1:name=" + tb.getName());System.out.println("tb1:name=" +((TBean)cache.get("bean")).getName());}}
class TBean implements java.io.Serializable{private static final long serialVersionUID = 1945562032261336919L;private String name;public String getName(){return name;}public void setName(String name){this.name = name;}} 多运行几次，查看控制台输入信息，会有更多体会。
