delay delivery of message in activeMQ in spring boot - spring-boot

Question

I want to send a message at any time 't' that will be received by the receiver after 'x' sec.
for doing so, I have written sender code
#Autowired
private JmsTemplate jmsTemplate;
private Queue queue = new ActiveMQQueue("topicName");
public void show(String message) {
try {
System.out.println("Sending message " + message);
jmsTemplate.convertAndSend(queue, message, new MessagePostProcessor() {
#Override
public Message postProcessMessage(Message message) throws JMSException {
System.out.println("postProcessMessage executed ");
message.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, 3 * 60 * 1000);
System.out.println("long time " + message
.getLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY));
return message;
}
});
System.out.println("Sending done " + message + " at " + System.currentTimeMillis());
} catch (Exception er) {
er.printStackTrace();
}
}
and Reciever code
#JmsListener(destination = "topicName")
public void reciever(String message) {
System.out.println("receiving message " + message + " at " + System.currentTimeMillis());
}
But message received by receiver instant .without any delay.
output is
Sending message this is a message postProcessMessage executed long
time 180000 receiving message this is a message at 1514391984964
Sending done this is a message at 1514391984970
configuration file is
#Bean
JmsTemplate createJMSTemplate(ConnectionFactory connectionFactory) {
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(connectionFactory);
return jmsTemplate;
}
#Bean
ConnectionFactory myActiveMQConnectionFactory() {
RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();
redeliveryPolicy.setBackOffMultiplier(1);
redeliveryPolicy.setUseExponentialBackOff(false);
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
connectionFactory.setRedeliveryPolicy(redeliveryPolicy);
NetworkConnector networkConnector = new DiscoveryNetworkConnector();
networkConnector.setConsumerTTL(2);
return connectionFactory;
}

Delayed message is not supported by activemq with default config, you should turn it on at first.
adding schedulerSupport in activemq.conf
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true">
