memcached循序渐进(二) Java下访问memcached简单代码

1. 下载客户端jar

  https://github.com/gwhalin/Memcached-Java-Client

2. 在Eclipse下新建一个小项目

   代码如下:

package memcached.java.client;

import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;

public class MemCacheInvoke {
    protected static MemCachedClient mcc = new MemCachedClient();

  static{

     /* 
      * 设置缓存服务器列表，当使用分布式缓存的时
      * 可以指定多个缓存服务器，这里将两个服务设置为一样
      */
       
      String[] servers =
      {
              "127.0.0.1:11211",
              "127.0.0.1:11211"
              //"server3.mydomain.com:1624"
      };

      //设置服务器权重
      Integer[] weights = {3, 2};

      // 创建一个Socked连接池实例
      SockIOPool pool = SockIOPool.getInstance();

      // 向连接池设置服务器和权重
      pool.setServers(servers);
      pool.setWeights(weights);

      // set some TCP settings
      // disable nagle
      // set the read timeout to 3 secs
      // and don't set a connect timeout
      pool.setNagle(false);
      pool.setSocketTO(3000);
      pool.setSocketConnectTO(0);

      // initialize the connection pool
      pool.initialize();
  }

  public static void main(String[] args) {
      mcc.set("foo", "This is in memcached");
      String bar = mcc.get("foo").toString();
      System.out.println(">>> " + bar);
  }

}

3. 运行结果
