在Java中設置Amazon ElastiCache w/spymemcached

我一直無法在Amazon Cloud上找到關於Memcached的良好教程，我對這整個緩存事情很陌生。我試圖通過亞馬遜的ElastiCache服務和一個間諜緩存客戶端使用memcached來實際進行memcached調用。在Java中設置Amazon ElastiCache w/spymemcached

下面是我在做什麼用Java現在：

try { 
     ConnectionFactoryBuilder connectionFactoryBuilder = new ConnectionFactoryBuilder(); 
     MemcachedClient memcachedClient = new MemcachedClient(
       connectionFactoryBuilder.build(), 
       AddrUtil.getAddresses("<beginning of cache node end point grabbed from AWS Console>.cache.amazonaws.com:11211")); 
     memcachedClient.set("test", 12, new Integer(12)); 
     System.out.println(memcachedClient.get("test")); 
    } catch (IOException ioException) { 
     ioException.printStackTrace(); 
    }

，我得到的錯誤，當我嘗試是這樣的：

任何人得到這個任何想法或經驗？謝謝！

你在哪裏執行此操作？在EC2實例中或從外部網絡中。請記住，ElastiCache服務器受限於訪問ElastiCAche實例的安全組。因此，請檢出安全組和允許您連接到Memcached服務器的其他配置。據我所知，ElastiCache不能從外部AWS邊界訪問

其餘代碼看起來不錯，並且cConsider使用像Spring這樣的框架來處理memcache客戶端對象實例化和相關配置。
