net spy memcached 使用demo

標籤：public   redist   another   expired   package   oid   dcl   unix時間   大於   

package memcached;import java.io.IOException;import java.net.InetSocketAddress;import net.spy.memcached.MemcachedClient;public class Client {private final int expiredSeconds = 100;private final InetSocketAddress server = new InetSocketAddress("127.0.0.1",10101);private MemcachedClient memcachedClient;public void init() {try {memcachedClient = new MemcachedClient(server);} catch (IOException e) {e.printStackTrace();}}public void put(String key, Object obj) {memcachedClient.set(key, expiredSeconds, obj);}public void delete(String key) {memcachedClient.delete(key);}public Object get(String key) {return memcachedClient.get(key);}public static void main(String args[]) {Client c = new Client();c.init();long begin = System.currentTimeMillis();for(int i=0;i<100;i++) {c.put(i+"", i);System.out.println(c.get(i+""));}System.out.println((System.currentTimeMillis()-begin)+"ms");}}

第一是設定到期時間。單位為秒，這裡注意在put的時候。該值作為set的一個參數，可是假設該值大於30天的秒數的話。就會當成是unix時間來設定到期時間而不是offset。

第二行是本地的一個memcached的server地址和port，調用MemcacedClient執行個體化一個MemcachedClient對象，以下就自己定義put。get，delete經常用法就能夠了

直接結果例如以下：
