JMS入门例子

JMS介绍，网上一大堆。然后要下载一个文件，链接https://activemq.apache.org/download-archives.html，选择一个版本下载。

直接贴代码：

package com.jms;

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

import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.activemq.command.ActiveMQQueue;

public class MessageSendAndReceive {

	/**
	 * @param args
	 * @throws JMSException
	 */
	public static void main(String[] args) throws JMSException {
		ConnectionFactory factory = new ActiveMQConnectionFactory("vm://localhost");

		Connection connection = factory.createConnection();
		connection.start();

		Queue queue = new ActiveMQQueue("testQueue");

		final Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		Message message = session.createTextMessage("Hello JMS!");

		MessageProducer producer = session.createProducer(queue);
		producer.send(message);

		System.out.println("Send Message Completed!");

		MessageConsumer comsumer = session.createConsumer(queue);
		Message recvMessage = comsumer.receive();
		System.out.println(((TextMessage) recvMessage).getText());
	}

}
