How to put a message back in the queue using latest SpringBoot and ActiveMQ classic - spring-boot

Question

I am designing a simple system where the flow is going to be like this:
Message Producer Microservice --> Active MQ --> Message Consumer Microservice --> Mongo DB
I need to design a queuing strategy in a way so that if MongoDB is down, I should not lose the message (because Message consumer will dequeue the message).
My consumer is written like this:
#JmsListener(destination = "Consumer.myconsumer.VirtualTopic.Tracking")
public void onReceiveFromQueueConsumer2(TrackingRequest trackingRequest) {
log.debug("Received tracking request from the queue by consumer 2");
log.debug(trackingRequest.toString());
}
How do you provide client acknowledgement?

Answer 1

You can use client acknowledge mode from your "Message Consumer Microservice." Since you're using a Spring JmsListener you can define the listener container using the containerFactory and then you can set the mode you want on your listener container using sessionAcknowledgeMode. See the Spring documentation for more details on what ack mode you might want to use here.
From the perspective of the ActiveMQ client you can configure redelivery semantics however you like in case of a failure. See the ActiveMQ documentation for more about that.

Answer 2

Alright, so I was able to solve this dilemma, here is what your config should be like (thanks to Justin for his valuable inputs):
#Bean
public ActiveMQConnectionFactory connectionFactory() {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
connectionFactory.setBrokerURL(brokerUrl);
connectionFactory.setPassword(userName);
connectionFactory.setUserName(password);
connectionFactory.setTrustAllPackages(true);
connectionFactory.setRedeliveryPolicy(redeliveryPolicy());
return connectionFactory;
}
#Bean
public JmsTemplate jmsTemplate() {
JmsTemplate template = new JmsTemplate();
template.setConnectionFactory(connectionFactory());
return template;
}
#Bean
public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
DefaultJmsListenerContainerFactory listenerCF = new DefaultJmsListenerContainerFactory();
listenerCF.setConnectionFactory(connectionFactory());
listenerCF.setSessionAcknowledgeMode(Session.AUTO_ACKNOWLEDGE);
listenerCF.setSessionTransacted(true);
return listenerCF;
}
#Bean
public RedeliveryPolicy redeliveryPolicy() {
RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();
redeliveryPolicy.setRedeliveryDelay(600000L); //keep trying every 10 minutes
redeliveryPolicy.setMaximumRedeliveries(-1); //Keep trying till its successfully inserted
return redeliveryPolicy;
}
