java memcache
引用：http://blog.iyunv.com/einarzhang/article/details/6064092Memcache的介绍有很多，这里给出如何在Java中应用Memcache的基本方法
1 安装Memcache服务器(windows)
下载windows版Memcache安装包，如memcached-1.2.6-win32-bin.zip，解压到指定位置，比如(D://memcache)，打开dos命令行，输入以下两个命令即可启动Memcache服务。
D:/memcache/memcached.exe -dinstall
D:/memcache/memcached.exe -dstart
2 下载Java版本的memcache客户端(以下列出常用的几种)。
spymemcached ：
http://code.google.com/p/spymemcached/
gwhalin / Memcached-Java-Client
https://github.com/gwhalin/Memcached-Java-Client/downloads
Jcache
http://code.google.com/intl/zh-CN/appengine/docs/java/memcache/usingjcache.html
3 下面给出两种方式调用Memcache
gwhalin / Memcached-Java-Client调用方式如下：

[*]public class MemcacheManagerForGwhalin {
[*]
[*] // 构建缓存客户端
[*] private static MemCachedClient cachedClient;
[*] // 单例模式实现客户端管理类
[*] private static MemcacheManagerForGwhalin INSTANCE = new MemcacheManagerForGwhalin();
[*]
[*] private MemcacheManagerForGwhalin() {
[*] cachedClient = new MemCachedClient();
[*] //获取连接池实例
[*] SockIOPool pool = SockIOPool.getInstance();
[*]
[*] //设置缓存服务器地址，可以设置多个实现分布式缓存
[*] pool.setServers(new String[]{"127.0.0.1:11211"});
[*]
[*] //设置初始连接5
[*] pool.setInitConn(5);
[*] //设置最小连接5
[*] pool.setMinConn(5);
[*] //设置最大连接250
[*] pool.setMaxConn(250);
[*] //设置每个连接最大空闲时间3个小时
[*] pool.setMaxIdle(1000 * 60 * 60 * 3);
[*]
[*] pool.setMaintSleep(30);
[*]
[*] pool.setNagle(false);
[*] pool.setSocketTO(3000);
[*] pool.setSocketConnectTO(0);
[*] pool.initialize();
[*] }
[*]
[*] /**
[*] * 获取缓存管理器唯一实例
[*] * @return
[*] */
[*] public static MemcacheManagerForGwhalin getInstance() {
[*] return INSTANCE;
[*] }
[*]
[*] @Override
[*] public void add(String key, Object value) {
[*] cachedClient.set(key, value);
[*] }
[*]
[*] @Override
[*] public void add(String key, Object value, int milliseconds) {
[*] cachedClient.set(key, value, milliseconds);
[*] }
[*]
[*] @Override
[*] public void remove(String key) {
[*] cachedClient.delete(key);
[*] }
[*]
[*] @Override
[*] public void remove(String key, int milliseconds) {
[*] cachedClient.delete(key, milliseconds, new Date());
[*] }
[*]
[*] @Override
[*] public void update(String key, Object value, int milliseconds) {
[*] cachedClient.replace(key, value, milliseconds);
[*] }
[*]
[*] @Override
[*] public void update(String key, Object value) {
[*] cachedClient.replace(key, value);
[*] }
[*]
[*]
[*] @Override
[*] public Object get(String key) {
[*] return cachedClient.get(key);
[*] }
[*]
[*]}
Spy方式调用如下:
[*]public class MemcacheManagerForSpy implements IMemcacheManager {
[*]
[*]
[*] //缓存客户端
[*] private MemcachedClient memcacheCient;
[*] //Manager管理对象，单例模式
[*] private static MemcacheManagerForSpy INSTANCE = new MemcacheManagerForSpy();
[*]
[*] private MemcacheManagerForSpy() {
[*] try {
[*] memcacheCient = new MemcachedClient(new InetSocketAddress("127.0.0.1",11211));
[*] } catch (IOException e) {
[*] e.printStackTrace();
[*] }
[*] }
[*]
[*] public static MemcacheManagerForSpy getInstance() {
[*] return INSTANCE;
[*] }
[*]
[*] @Override
[*] public void add(String key, Object value, int milliseconds) {
[*] memcacheCient.add(key, milliseconds, value);
[*] }
[*]
[*] @Override
[*] public void add(String key, Object value) {
[*] memcacheCient.add(key, 3600, value);
[*]
[*] }
[*]
[*] @Override
[*] public void remove(String key, int milliseconds) {
[*] memcacheCient.delete(key);
[*] }
[*]
[*] @Override
[*] public void remove(String key) {
[*] memcacheCient.delete(key);
[*] }
[*]
[*] @Override
[*] public void update(String key, Object value, int milliseconds) {
[*] memcacheCient.replace(key, milliseconds, value);
[*] }
[*]
[*] @Override
[*] public void update(String key, Object value) {
[*] memcacheCient.replace(key, 3600, value);
[*] }
[*]
[*] @Override
[*] public Object get(String key) {
[*] returnmemcacheCient.get(key);
[*] }
[*]}
