producer端

代码语言:javascript复制
 public static void main(String[] args) {
        ConnectionFactory connect = new ActiveMQConnectionFactory("tcp://192.168.0.100:61616");
        try {
            //创建连接对象
            Connection connection = connect.createConnection();
            connection.start();
            //第一个值表示是否使用事务,如果选择true,第二个值相当于选择0
            Session session = connection.createSession(true, Session.SESSION_TRANSACTED);
            //使用队列queue
            Queue testqueue = session.createQueue("boss drink");
            //创建提供者
            MessageProducer producer = session.createProducer(testqueue);
            TextMessage textMessage=new ActiveMQTextMessage();
            textMessage.setText("我渴了,我要喝水!");
            producer.setDeliveryMode(DeliveryMode.PERSISTENT);
            producer.send(textMessage);
            session.commit();// 事务型消息,必须提交后才生效
            connection.close();
 
        } catch (JMSException e) {
            e.printStackTrace();
        }
 
    }
