disruptor入门例子:

import java.util.concurrent.ExecutorService;
import java.util.concurrent.SynchronousQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

import com.taobao.eagleeye.digest.handler.DigestJob;
import com.taobao.eagleeye.digest.handler.DigesterWorkerHanlder;
import com.taobao.eagleeye.disruptor.EventHandler;
import com.taobao.eagleeye.disruptor.RingBuffer;
import com.taobao.eagleeye.disruptor.dsl.Disruptor;
import com.taobao.tlog.util.NamedThreadFactory;

public class Test {

	private static final int RING_BUFFER_SIZE = 8;

	public static void main(String[] args) {
		ExecutorService es = new ThreadPoolExecutor(0, Integer.MAX_VALUE,
                60L, TimeUnit.SECONDS,
                new SynchronousQueue<Runnable>(),new NamedThreadFactory("disruptor-process"));
		Disruptor<DigestJob> disruptor = new Disruptor<DigestJob>(DigestJob.EVENT_FACTORY, RING_BUFFER_SIZE, es);
		DigesterWorkerHanlder[] workers = new DigesterWorkerHanlder[12];
		disruptor.handleEventsWith(new EventHandler<DigestJob>() {

			@Override
			public void onEvent(DigestJob event, long sequence, boolean endOfBatch) throws Exception {
				System.out.println("event=" + event);
				Thread.sleep(10000);
			}

		});
		RingBuffer<DigestJob> ringBuffer = disruptor.start();
		while (true) {
			long seq = ringBuffer.next();
			DigestJob job = ringBuffer.get(seq);
			job.context = null;
			ringBuffer.publish(seq);
			System.out.println("emit..."+seq);
			try {
				Thread.sleep(100);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
}

				return new String();
			}
		};

		ExecutorService es = Executors.newCachedThreadPool(namedThreadFactory);

		Disruptor<String> disruptor = new Disruptor<String>(EVENT_FACTORY, 8, es);
