基于ActiveMQ开发示例代码

Producer

package activemq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class SendMessage {
	private static final String url = "tcp://localhost:61616";
	private static final String QUEUE_NAME = "choice.queue";
	protected String expectedBody = "<hello>world!</hello>";

	public void sendMessage() throws JMSException {
		Connection connection = null;
		try {
			ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
					url);
			connection = (Connection) connectionFactory.createConnection();
			connection.start();
			Session session = (Session) connection.createSession(false,
					Session.AUTO_ACKNOWLEDGE);
			Destination destination = session.createQueue(QUEUE_NAME);
			MessageProducer producer = session.createProducer(destination);
			TextMessage message = session.createTextMessage(expectedBody);
			message.setStringProperty("headname", "remoteB");
			producer.send(message);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void main(String[] args) {
		SendMessage sndMsg = new SendMessage();
		try {
			sndMsg.sendMessage();
		} catch (Exception ex) {
			System.out.println(ex.toString());
		}
	}
}

 Consumer

package activemq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnectionFactory;

public class ReceiveMessage {
	private static final String url = "tcp://localhost:61616";
	private static final String QUEUE_NAME = "choice.queue";

	public void receiveMessage() {
		Connection connection = null;
		try {
			try {
				ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
						url);
				connection = connectionFactory.createConnection();
			} catch (Exception e) {
				System.out.println(e.toString());
			}
			connection.start();
			Session session = connection.createSession(false,
					Session.AUTO_ACKNOWLEDGE);
			Destination destination = session.createQueue(QUEUE_NAME);
			MessageConsumer consumer = session.createConsumer(destination);
			consumeMessagesAndClose(connection, session, consumer);
		} catch (Exception e) {
			System.out.println(e.toString());
		}
	}

	protected void consumeMessagesAndClose(Connection connection,
			Session session, MessageConsumer consumer) throws JMSException {
		for (int i = 0; i < 1;) {
			Message message = consumer.receive(1000);
			if (message != null) {
				i++;
				onMessage(message);
			}
		}
		System.out.println("Closing connection");
		consumer.close();
		session.close();
		connection.close();
	}

	public void onMessage(Message message) {
		try {
			if (message instanceof TextMessage) {
				TextMessage txtMsg = (TextMessage) message;
				String msg = txtMsg.getText();
				System.out.println("Received: " + msg);
			}
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	public static void main(String args[]) {
		ReceiveMessage rm = new ReceiveMessage();
		rm.receiveMessage();
	}

}
