在eclipse中新建一個工程，將上面下載的java_memcached-release_2.0.1.jar引入工程。
      新建java類memcachedTest
    import com.danga.MemCached.MemCachedClient;
import com.danga.MemCached.SockIOPool;

public class memcachedTest {
 // create a static client as most installs only need
 // a single instance
 protected static MemCachedClient mcc = new MemCachedClient();
 
 //連接memcache
 static{
  
  // set up connection pool once at class load
  // server list and weights
  String[] servers =
   {
        "192.168.0.20:11211",
     "192.168.0.20:11212"
   };

  Integer[] weights = { 3,2 };

  // grab an instance of our connection pool
  SockIOPool pool = SockIOPool.getInstance();

  // set the servers and the weights
  pool.setServers( servers );
  pool.setWeights( weights );

  // set some basic pool settings
  // 5 initial, 5 min, and 250 max conns
  // and set the max idle time for a conn
  // to 6 hours
  pool.setInitConn( 5 );
  pool.setMinConn( 5 );
  pool.setMaxConn( 250 );
  pool.setMaxIdle( 1000 * 60 * 60 * 6 );

  // set the sleep for the maint thread
  // it will wake up every x seconds and
  // maintain the pool size
  pool.setMaintSleep( 30 );

  // 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();

  // lets set some compression on for the client
  // compress anything larger than 64k
  mcc.setCompressEnable( true );
  mcc.setCompressThreshold( 64 * 1024 );
  
  
 }
 public static void main(String[] a){
  for(int i=0;i<1000;i++){
      mcc.set( "Test_"+i, "hello world_"+i);
  }
  //第一次運行講一下三行注釋，用以上面三行進行數據插入，以后運行就將上面三行注釋，運行下面三行語句來看執行效果。

  System.out.println("dd1="+(String)mcc.get( "Test_967"));
  System.out.println("dd2="+(String)mcc.get( "Test_984"));
  System.out.println("dd3="+(String)mcc.get( "Test_981"));
  
  System.out.println("End"); 
 }

}
