 生产任务

　　　　public static void main(String[] args) throws JMSException {
		
		//连接工厂
		ConnectionFactory factory = new ActiveMQConnectionFactory();
		//获取一个连接
		Connection connection = factory.createConnection();
		//建立会话
		Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
		//创建队列化话题对象
		Queue queue = session.createQueue("hello");
		MessageProducer producer = session.createProducer(queue);
		for (int i = 0; i < 10; i++) {
			producer.send(session.createTextMessage("ActiveMQ"+i));
		}
		session.commit();
	}

　　产生了十条任务

消费（处理业务）

public static void main(String[] args) throws Exception {
		//连接工厂
		ConnectionFactory factory = new ActiveMQConnectionFactory();
		//获取一个连接
		Connection connection = factory.createConnection();
		connection.start();
		//建立会话
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		//创建队列化话题对象
		Queue queue = session.createQueue("hello");
		MessageConsumer producer = session.createConsumer(queue);
		while(true){
			//接收消息
			TextMessage receive = (TextMessage) producer.receive();
			if(receive!=null){
				System.out.println(receive.getText());
			}
