最初重新连接到JMS服务器并在获得先前的连接之后

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
        "tcp://localhost:61616");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("myQueue");
MessageProducer producer = session.createProducer(queue);
Message message = session.createTextMessage("Hello, JMS!");
producer.send(message);
connection.close();
