用spymemcached将对象存入缓存

1. import java.net.InetSocketAddress;  
2. import java.util.concurrent.Future;  
3.   
4. import net.spy.memcached.MemcachedClient;  
5.   
6. public class MClient {  
7.   
8.     public static void main(String[] args){  
9.         try{  
10.             /*建立MemcachedClient 实例，并指定memcached服务的IP地址和端口号*/  
11.             MemcachedClient mc = new MemcachedClient(new InetSocketAddress("192.168.1.20", 12111));  
12.             Future<Boolean> b = null;  
13.             /*将key值，过期时间(秒)和要缓存的对象set到memcached中*/  
14.             b = mc.set("neea:testDaF:ksIdno", 900, "someObject");  
15.             if(b.get().booleanValue()==true){  
16.                 mc.shutdown();  
17.             }  
18.         }  
19.         catch(Exception ex){  
20.             ex.printStackTrace();  
21.         }  
22.     }  
23. }
