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。
