1、先熟悉下什么是阻塞队列！

2、代码压测

2.1、公共部分

package com.bfxy.disruptor.ability;

public interface Constants {

    int EVENT_NUM_OHM = 100000000;
    
    int EVENT_NUM_FM = 50000000;
    
    int EVENT_NUM_OM = 10000000;
    
}

package com.bfxy.disruptor.ability;

import java.io.Serializable;

public class Data implements Serializable {

    private static final long serialVersionUID = 2035546038986494352L;
    private Long id ;
    private String name;
    
    public Data() {
    }
    public Data(Long id, String name) {
        super();
        this.id = id;
        this.name = name;
    }
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

2.2、ArrayBlockingQueue压测

package com.bfxy.disruptor.ablility;

import com.bfxy.disruptor.ability.Data;

import java.util.concurrent.ArrayBlockingQueue;

public class ArrayBlockingQueue4Test {

    public static void main(String[] args) {
        final ArrayBlockingQueue queue = new ArrayBlockingQueue<>(100000000);
        final long startTime = System.currentTimeMillis();
        // 向容器中添加元素
        new Thread(new Runnable() {
            @Override
            public void run() {
                long i = 0;
                while(i < Constants.EVENT_NUM_FM) {
                    try {
                        queue.put(new Data(i, "c"+i));
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    i++;
                }
            }
        }).start();
        // 从容器中取出元素
        new Thread(new Runnable() {
            @Override
            public void run() {
                long k = 0;
                while (k < Constants.EVENT_NUM_FM) {
                    try {
                        queue.take();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    k++;
                }
                long endTime = System.currentTimeMillis();
                System.out.println("ArrayBlockingQueue costTime = " + (endTime - startTime) + "ms");
            }
        }).start();
    }
}

2.3、DisruptorSingle压测

package com.bfxy.disruptor.ability;

import com.lmax.disruptor.EventHandler;

public class DataConsumer implements EventHandler {

    private long startTime;
    private int i;

    public DataConsumer() {
        this.startTime = System.currentTimeMillis();
    }

    @Override
    public void onEvent(Data data, long seq, boolean bool)
            throws Exception {
        i++;
        if (i == Constants.EVENT_NUM_OHM) {
            long endTime = System.currentTimeMillis();
            System.out.println("Disruptor costTime = " + (endTime - startTime) + "ms");
        }
    }

}

package com.bfxy.disruptor.ability;

import java.util.concurrent.Executors;

import com.lmax.disruptor.BlockingWaitStrategy;
import com.lmax.disruptor.BusySpinWaitStrategy;
import com.lmax.disruptor.EventFactory;
import com.lmax.disruptor.RingBuffer;
import com.lmax.disruptor.YieldingWaitStrategy;
import com.lmax.disruptor.dsl.Disruptor;
import com.lmax.disruptor.dsl.ProducerType;

public class DisruptorSingle4Test {

    public static void main(String[] args) {
        int ringBufferSize = 65536;
        final Disruptor disruptor = new Disruptor(
                 new EventFactory() {
                     @Override
                    public Data newInstance() {
                        return new Data();
                    }
                },
                ringBufferSize,
                Executors.newSingleThreadExecutor(),
                ProducerType.SINGLE, 
                //new BlockingWaitStrategy()
                new YieldingWaitStrategy()
                );

        DataConsumer consumer = new DataConsumer();
        //消费数据
        disruptor.handleEventsWith(consumer);
        disruptor.start();
        new Thread(new Runnable() {
            @Override
            public void run() {
                RingBuffer ringBuffer = disruptor.getRingBuffer();
                for (long i = 0; i < Constants.EVENT_NUM_OHM; i++) {
                    long seq = ringBuffer.next();
                    Data data = ringBuffer.get(seq);
                    data.setId(i);
                    data.setName("c" + i);
                    ringBuffer.publish(seq);
                }
            }
        }).start();
    }
}
