memcache java客户端代码示例

Memcache是danga.com的一个开源项目，它是一个高性能的分布式的内存对象缓存系统，通过在内存里维护一个统一的巨大的Hash表，能够用来存储各种格式的数据。 总结下memcache java客户端代码示例，不是很全。

        pool.setInitConn(10);//设置初始连接数
        pool.setMinConn(5); //设置最小连接数
        pool.setMaintSleep(30);//设置连接池维护线程的睡眠时间
        pool.setNagle(false); //是否使用nagle算法
        pool.setSocketConnectTO(3000);// 设置socket的读取等待超时时间
        pool.setAliveCheck(true);//设置连接心跳检测开关
        pool.setHashingAlg(SockIOPool.CONSISTENT_HASH);// 设置hash算法
