Errors in implementing Memcache in java
提问by Anil Kumar
I'm trying to write a simple code in Java to connect to a memcache server . I using the spymemcached 2.8 jar but I am getting a "server reconnecting" error which I'm unable to understand.
我正在尝试用 Java 编写一个简单的代码来连接到 memcache 服务器。我使用的是 spymemcached 2.8 jar，但出现“服务器重新连接”错误，我无法理解。
Code is:
代码是：
**client = new MemcachedClient(new BinaryConnectionFactory(),AddrUtil.getAddresses("127.0.0.1:11211"));
} catch (IOException e) {
e.printStackTrace();
System.err.println("connection problem");
}
client.set("someKey", 3600, new Integer(10));
Object myObject=temp.client.get("someKey");
System.out.println(myObject);
client.delete("someKey");**
But I'm getting errors which are:
但我收到以下错误：

Timed out waiting for operation - failing node: /127.0.0.1:11211this means your memcached binded on other adress or it's not started.
Timed out waiting for operation - failing node: /127.0.0.1:11211这意味着您的 memcached 已绑定到其他地址或尚未启动。

Sorry guys, there was some problem with my machine, that's why I was having so many troubles running a simple code. But when I tried on a different box and used it's IP den it worked fine... :)
