本文通过一个Java示例展示了如何使用Spymemcached库进行Memcached客户端操作，包括设置、获取、添加、替换及删除键值等基本功能。

package cn.com.memcachedemo.memcachedemo.d002;

import java.io.IOException;
import java.io.Serializable;
import java.net.InetSocketAddress;
import java.util.Date;
import net.spy.memcached.MemcachedClient;

/**

<dependency>
        <groupId>net.spy</groupId>
        <artifactId>spymemcached</artifactId>
        <version>2.9.1</version>
</dependency>

public class MemcacheUse {
    private static class TestKey implements Serializable {
        private static final long serialVersionUID = 1L;
        private long d = new Date().getTime();
        public String toString() {
            return "TestKey ["+d+"]";
        }
    }

    public static void main(String[] args) throws IOException {

        MemcachedClient c=new MemcachedClient(new InetSocketAddress("192.168.1.109", 12000));

        // Store a value (async) for one hour
        TestKey myData = new TestKey();
        //兼有add 和set于一身，不存在则添加，存在则替换
        c.set("someKey", 3600, myData);

        //不存在则添加,否则不成功
        c.add("Hello2", 1000, "Memcache3");

        //存在则替换,否则不成功
        c.replace("Hello4", 1000, "软件开发4");
        c.set("Hello4", 3600, "软件开发4");

        c.delete("Hello4");



//      System.out.println(c.getAvailableServers());
        // Retrieve a value (synchronously).
        TestKey myObject=(TestKey)c.get("someKey");
        System.out.println(c.get("Hello2"));
        System.out.println(c.get("Hello"));
        System.out.println(c.get("Hello4"));
        System.out.println(c.getStats());
        System.out.println(myObject.toString());

        c.shutdown();
    }
}
