RabbitMQ 简单测试

RabbitMQ 测试

RabbitMQ 基于Erlang 实现， 客户端可以用Python | Java | Ruby | PHP | C# | Javascript | Go等语言来实现。这里做个java语言的测试。

首先安装好RabbitMQ 服务端。

maven依赖

<dependency>
        <groupId>com.rabbitmq</groupId>
        <artifactId>amqp-client</artifactId>
        <version>3.0.4</version>
</dependency>
<dependency>
	<groupId>commons-lang</groupId>
	<artifactId>commons-lang</artifactId>
	<version>2.6</version>
</dependency>

java测试代码如下：

//定义队列
EndPoint.java
public abstract class EndPoint{

    protected Channel channel;
    protected Connection connection;
    protected String endPointName;

    public EndPoint(String endpointName) throws IOException{
         this.endPointName = endpointName;

         //Create a connection factory
         ConnectionFactory factory = new ConnectionFactory();

         //hostname of your rabbitmq server
         factory.setHost("192.168.163.33");
         factory.setPort(5672);
         factory.setUsername("test");
         factory.setPassword("test");

         //creating a channel
         channel = connection.createChannel();

         //declaring a queue for this channel. If queue does not exist,
         //it will be created on the server.
         channel.queueDeclare(endpointName, false, false, false, null);
    }

    /**
     * Close channel and connection. Not necessary as it happens implicitly any way.
     * @throws IOException
     */
     public void close() throws IOException{
         this.channel.close();
         this.connection.close();
     }
}

//生产者
Producer.java
public class Producer extends EndPoint{

	public Producer(String endPointName) throws IOException{
		super(endPointName);
	}

	public void sendMessage(Serializable object) throws IOException {
	    channel.basicPublish("",endPointName, null, SerializationUtils.serialize(object));
	}
}

//消费队列
QueueConsumer.java
public class QueueConsumer extends EndPoint implements Runnable, Consumer{

	public QueueConsumer(String endPointName) throws IOException{
		super(endPointName);
	}

	public void run() {
		try {
			//start consuming messages. Auto acknowledge messages.
			channel.basicConsume(endPointName, true,this);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	/**
	 * Called when consumer is registered.
	 */
	public void handleConsumeOk(String consumerTag) {
		System.out.println("Consumer "+consumerTag +" registered");
	}

	/**
	 * Called when new message is available.
	 */
	public void handleDelivery(String consumerTag, Envelope env,
			BasicProperties props, byte[] body) throws IOException {
		Map map = (HashMap)SerializationUtils.deserialize(body);
	    System.out.println("Message Number "+ map.get("message number") + " received.");

	}

	public void handleCancel(String consumerTag) {}
	public void handleCancelOk(String consumerTag) {}
	public void handleRecoverOk(String consumerTag) {}
	public void handleShutdownSignal(String consumerTag, ShutdownSignalException arg1) {}
}

//测试用例
Main.java
public class Main {
	public Main() throws Exception{

		QueueConsumer consumer = new QueueConsumer("queue");
		Thread consumerThread = new Thread(consumer);
		consumerThread.start();

		Producer producer = new Producer("queue");

		for (int i = 0; i < 100000; i++) {
			HashMap message = new HashMap();
			message.put("message number", i);
			producer.sendMessage(message);
			System.out.println("Message Number "+ i +" sent.");
		}
	}

	/**
	 * @param args
	 * @throws SQLException
	 * @throws IOException
	 */
	public static void main(String[] args) throws Exception{
	  new Main();
	}
}

运行报以下错误

解决方法这个 或者这个

网上Rabbit性能测试

性能测试



上图可以看到每秒百万级别的消息进出数量，以及2343条的消息在队列中等待。
