如何使用Spymemcached认证到Redis Cloud Memcached？

import net.spy.memcached.AddrUtil;
import net.spy.memcached.MemcachedClient;
import net.spy.memcached.auth.AuthDescriptor;
import net.spy.memcached.auth.PlainCallbackHandler;

public class SpymemcachedExample {
    public static void main(String[] args) {
        try {
            // 创建MemcachedClient对象
            MemcachedClient client = new MemcachedClient(AddrUtil.getAddresses("rediscloud-memcached-host:port"));

            // 设置认证信息
            AuthDescriptor authDescriptor = new AuthDescriptor(new String[]{"PLAIN"},
                    new PlainCallbackHandler("username", "password"));
            client.setAuthDescriptor(authDescriptor);

            // 连接到Redis Cloud Memcached
            client.addServer("rediscloud-memcached-host", port);

            // 进行操作
            client.set("key", 0, "value");
            Object result = client.get("key");
            System.out.println(result);

            // 关闭连接
            client.shutdown();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
