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

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。
