We're trying to set a delay on some JMS messages, so that a message will only be added to the queue/ received by the listener after x time. So far we've tried 2 approaches that didn't work.
1) According to the spring documentation, we can set the delivery delay on the JMSTemplate. This is the sample code we tried:
@Autowired
private JmsTemplate jmsTemplate;
...
long deliveryDelay = ...;
this.jmsTemplate.setDeliveryDelay(deliveryDelay);
this.jmsTemplate.convertAndSend(
queue.getName(),
event);
...
However, we get the following exception, even though our spring jms version is 4.0.5:
java.lang.IllegalStateException: setDeliveryDelay requires JMS 2.0
2) We also tried setting the delay on the message itself, but it looks like the delay was ignored, and the message was delivered immediately anyway.
@Component
public class MyMessageConverter implements MessageConverter {
...
@Override
public Message toMessage(Object eventObject, Session session) throws JMSException, MessageConversionException {
...
long deliveryDelay = ...;
objectMessage.setLongProperty(
ScheduledMessage.AMQ_SCHEDULED_DELAY,
deliveryDelay);
return objectMessage;
}
}
The jmsTemplate definition in the spring xml:
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory" ref="cachingConnectionFactory" />
<property name="messageConverter" ref="myMessageConverter" />
<property name="sessionTransacted" value="true" />
</bean>
Does anyone has any suggestions on what the problems are / other ideas on how to achieve delayed messaging? Thanks!

You can also define a new, delaying JmsTemplate which you can autowire where needed:
@Bean
public JmsTemplate jmsTemplate(){
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setConnectionFactory(connectionFactory());
return jmsTemplate;
}
@Bean
public JmsTemplate delayingJmsTemplate(){
JmsTemplate jmsTemplate = new JmsTemplate();
jmsTemplate.setDeliveryDelay(1000);
jmsTemplate.setConnectionFactory(connectionFactory());
return jmsTemplate;
}
...
@Autowired
private JmsTemplate jmsTemplate;
@Autowired
private JmsTemplate delayingJmsTemplate;

The JMS 2.0 is not supported in the activemq package. Try using artemis instead. Try replacing the package name from
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-activemq</artifactId>
<version>1.5.6.RELEASE</version>
</dependency>
into
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-artemis</artifactId>
<version>1.5.6.RELEASE</version>
</dependency>
and also add in the application.properties
spring.artemis.mode=native
spring.artemis.host=localhost
spring.artemis.port=61616
spring.artemis.user=admin
spring.artemis.password=admin

The comments give the answer. By default scheduled message support is disabled. You must enabled it in the broker XML configuration file as mentioned on the documentation page.
An example Broker tag with scheduler support enabled:
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true">
You must of course restart the broker in order for configuration changes to take affect. Then when you send a message you need to add the JMS headers that tell the broker what type of delay you want.
message.setIntProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, scheduledDelay);

I have added schedulerSupport=true
in active mq configuration xml. Please dont forget to restart the active mq server after configuration changes. Once you restart and login to "Scheduled" tab on admin console of activemq, you would see scheduled message details.
jmsTemplate.setDeliveryDelay
did not work for me so I added the below piece of code :
used
jmsTemplate.convertAndSend(queueName, object, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws JMSException {
message.setIntProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, scheduledDelay);
return message;
}
});
Please note : It was not working for me in the beginning. But what was needed was an restart on activeMQ server to reflect the changes in config

Two things needs to be done to resolve this.
broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true">
Set the delay before sending the message.
public void send(Object object) {
log.info("put <" + object + ">");
jmsTemplate.convertAndSend(QUEUE_NAME, object, m -> {
m.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, 10000);
return m;
});
}

Documentation http://activemq.apache.org/delay-and-schedule-message-delivery.html
Example: after 10 sec received message by consumer
public void send(Object object) {
log.info("put <" + object + ">");
jmsTemplate.convertAndSend(QUEUE_NAME, object, m -> {
m.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, 10000);
return m;
});
}

jmsTemplate.convertAndSend(destination, message, new MessagePostProcessor() {
@Override
public Message postProcessMessage(Message message) throws JMSException {
message.setIntProperty("JMS_OracleDelay", 200);
return message;
}
});

Also according to method from ActiveMQ BrokerService class you should configure persistence to have ability to use scheduler functionality.
public boolean isSchedulerSupport() {
return this.schedulerSupport && (isPersistent() || jobSchedulerStore != null);
}
