Issue with RabbitMQ Delay message in spring boot - spring-boot

Question

I am facing an issue in Rabbit MQ regarding x-delay while connecting to spring boot. I need to schedule the messages for a variable delay according to the message type. It can be one of the units MINUTE, DAY, WEEK, MONTH, and so on…
Below is my configuration class :
private final RabbitProperties rabbitProperties;
private final Environment environment;
#Bean
public Queue rabbitMQueue() {
return new Queue(environment.getProperty(RABBITMQ_QUEUE_NAME), false);
}
#Bean
public Exchange rabbitExchange() {
String exchangeName = "test_exchange";
Map<String, Object> exchangeArgs = new HashMap<>();
exchangeArgs.put("x-delayed-type", exchangeType.toLowerCase());
exchangeArgs.put("x-delayed-message",true);
exchangeArgs.put("x-message-ttl",9922);
log.info("Loading {} exchange with name {}.", exchangeType, exchangeName);
switch (exchangeType){
default: return new CustomExchange(exchangeName, exchangeType, true, false, exchangeArgs);
case "DIRECT" : return directExchange(exchangeName, exchangeArgs);
}
}
private Exchange directExchange(String exchangeName, Map<String, Object> exchangeArgs) {
// log.info("Generating directExchange");
// DirectExchange directExchange = new DirectExchange(exchangeName,true, false, exchangeArgs);
// directExchange.setDelayed(true);
// return directExchange;
return ExchangeBuilder.directExchange(exchangeName).withArguments(exchangeArgs)
.delayed()
.build();
}
#Bean
public Binding rabbitBinding(final Queue rabbitMQueue, final Exchange rabbitExchange){
log.info("Exchange to bind : {}", rabbitExchange.getName());
return BindingBuilder
.bind(rabbitMQueue)
.to(rabbitExchange)
.with(environment.getProperty(RABBITMQ_ROUTING_KEY)).noargs();
}
#Bean
public AmqpTemplate amqpTemplate(final ConnectionFactory rabbitMQConnectionFactory,
final MessageConverter rabbitMessageConvertor,
final Exchange rabbitExchange){
RabbitTemplate rabbitTemplate = new RabbitTemplate(rabbitMQConnectionFactory);
rabbitTemplate.setMessageConverter(rabbitMessageConvertor);
rabbitTemplate.setExchange(rabbitExchange.getName());
return rabbitTemplate;
}
#Bean
public ConnectionFactory rabbitMQConnectionFactory(){
Boolean isUriBased = environment.getProperty(URI_BASED_CONNECTION_ENABLED, Boolean.class);
CachingConnectionFactory connectionFactory;
if(!Objects.isNull(isUriBased) && isUriBased){
connectionFactory = new CachingConnectionFactory();
connectionFactory.setUri(environment.getProperty(RABBITMQ_URI));
}
else{
connectionFactory = new CachingConnectionFactory(rabbitProperties.getHost(), rabbitProperties.getPort());
connectionFactory.setUsername(rabbitProperties.getUsername());
connectionFactory.setPassword(rabbitProperties.getPassword());
}
return connectionFactory;
}
#Bean
public MessageConverter rabbitMessageConvertor(){
return new Jackson2JsonMessageConverter();
}
And publisher code :
public boolean sendMessage(String tenant, T message, int delay){
MyQueueMessage<T> myQueueMessage = getQueueMessage(tenant, message);
try{
amqpTemplate.convertAndSend(exchangeName, routingKey, myQueueMessage, messagePostProcessor -> {
// MessageProperties messageProperties = messagePostProcessor.getMessageProperties();
messagePostProcessor.getMessageProperties().setHeader("x-message-ttl", 5011);
messagePostProcessor.getMessageProperties().setHeader(MessageProperties.X_DELAY, 5012);
messagePostProcessor.getMessageProperties().setDelay(5013);
messagePostProcessor.getMessageProperties().setReceivedDelay(5014);
log.info("Setting delay in properties : {}", messagePostProcessor.getMessageProperties().getHeader(MessageProperties.X_DELAY).toString());
return messagePostProcessor;
});
} catch (Exception e){
return false;
}
return true;
}
And receiver :
#RabbitListener(queues = "INVOICE")
public void receiveMessage(Message message){
log.info("Message Received : " + message.toString() + " with delay " + message.getMessageProperties().getDelay());
}
}
Issue :
The value
message.getMessageProperties().getDelay()
comes as NULL in the receiver and the message is also not delayed. It’s getting received instantly.
Did I miss anything?
Please note that I am using docker, rabbitmq-management-3, and have already installed the rabbitmq_delayed_message_exchange plugin.
