下载

进入下载页面：http://activemq.apache.org/activemq-541-release.html，下载zip包

然后启动起来，windows下可以直接运行bin下的activemq.bat

创建发送端

ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
QueueConnection connection = factory.createQueueConnection();
QueueSession session = connection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("queue");
QueueSender sender = session.createSender(queue);
TextMessage message = session.createTextMessage();
message.setText("Hello ActiveMQ");
sender.send(message);
connection.close();

创建接收端

ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
QueueConnection queueConnection = factory.createQueueConnection();
QueueSession session = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue(txtKeyWord.getText());
QueueReceiver receiver = session.createReceiver(queue);
receiver.setMessageListener(new MessageListener() {
	public void onMessage(Message message) {
		if(message instanceof TextMessage){
			TextMessage textMessage = (TextMessage)message;
			try {
				textArea.append(">>" + textMessage.getText() + "\n");
				textArea.setCaretPosition(textArea.getDocument().getLength());
				textMessage.acknowledge();
			} catch (JMSException e) {
				e.printStackTrace();
			}
		}
	}
});
queueConnection.start();
