Apache ActiveMQ传输持续时间

Question

我试图估计发送者和接收者之间的ActiveMQ通信的转移持续时间。我不知道我怎么能同时得到我的变量sending_time和reception_time，所以我可以估计transfert_duration = reception_time - 发送时间。

            connection = factory.createConnection();
            connection.start();
            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            destination = session.createQueue("QUEUE");
            producer = session.createProducer(destination);
            TextMessage message = session.createTextMessage();

            message.setText("Hello");

            sending_time = System.currentTimeMillis();

            producer.send(message);
            
            
            System.out.println("Sent : " + message.getText());

        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
    	
        Sender sender = new Sender();
        sender.sendMessage();
    }

}
