Actually in my RabbitMQ config I have declared 10 consumers for each queue. So all consumer threads are created before my Spring Boot application is fully up so it is taking time on application startup.
I want to lazy load all my Rabbitmq queue when my project is up. I tried using @Lazy on the configuration class but it does not seem working.
Is there any way to declare lazy load queue ?
Set autoStartup="false" on the @RabbitListener (or listener container).
Then start the listeners manually.
https://docs.spring.io/spring-amqp/docs/current/reference/html/#container-management
for @RabbitListener or just start() the containers if they are beans.
All you need to do is set "autoStartup=false" to @RabbitListener:
@RabbitListener(queues = "${yourqueue}",autoStartup = "false")
And then find all registered rabbit listeners and start it:
public static void main(String[] args) {
ConfigurableApplicationContext run = SpringApplication.run(SimPurchaseApplication.class, args);
RabbitListenerEndpointRegistry rabbitListeners = run.getBean(RabbitListenerEndpointRegistry.class);
for (MessageListenerContainer listenerContainer : rabbitListeners.getListenerContainers()){
listenerContainer.start();
}
}
