IOException이 자바에서 memcached와의 설정 작업에

Question

내 자바 코드는 IOException가 및 memcache 서버를주고있다

가 다시 연결 ..

코드 :

public class Memcache implements Serializable { 

    MemcachedClient client; 

    public static final int EXP_TIME = 10; 
    public static final String KEY = "spoon"; 

    public static void main(String[] args)throws IOException{ 
     Memcache temp=new Memcache(); 
     Dummy dummy= new Dummy("Hello World"); 

     try { 
      temp.client = new MemcachedClient(new InetSocketAddress("localhost", 11211)); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      System.err.println("connection problem"); 
     } 
     temp.obj=temp.client.getAvailableServers(); 
     System.out.println(temp.obj); 
     temp.obj1=temp.client.getUnavailableServers(); 
     System.out.println(temp.obj1); 
     temp.client.add(KEY, EXP_TIME, dummy); 
     Object myObject=temp.client.get(KEY); 
     System.out.println(myObject); 
     temp.client.delete(KEY); 
    } 
} 

코드를 디버깅했지만 설정 작업에 도달했을 때 IOException n disconnected가 발생했습니다. 더미에 대한

코드는 다음과 같습니다

import java.io.Serializable; 

public class Dummy implements Serializable { 
    String one; 

    public Dummy(String one){ 
     this.one=one; 
    } 
}

문제를 디버깅하려면, 요청이 시작된 서버에서 memcached를 텔넷을 시도하시기 바랍니다. memcached가 명시 적으로 IP 주소를 언급하기 시작하면 다른 호스트에 대한 연결을 거부 할 수 있습니다.
