在Java中设置Amazon ElastiCache w/spymemcached

我一直无法在Amazon Cloud上找到关于Memcached的良好教程，我对这整个缓存事情很陌生。我试图通过亚马逊的ElastiCache服务和一个间谍缓存客户端使用memcached来实际进行memcached调用。在Java中设置Amazon ElastiCache w/spymemcached

下面是我在做什么用Java现在：

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(); 
    }

，我得到的错误，当我尝试是这样的：

任何人得到这个任何想法或经验？谢谢！

你在哪里执行此操作？在EC2实例中或从外部网络中。请记住，ElastiCache服务器受限于访问ElastiCAche实例的安全组。因此，请检出安全组和允许您连接到Memcached服务器的其他配置。据我所知，ElastiCache不能从外部AWS边界访问

其余代码看起来不错，并且cConsider使用像Spring这样的框架来处理memcache客户端对象实例化和相关配置。
