I am struggling hard to find out the way for scheduled/Delaying messages in Spring AMQP/Rabbit MQ.
After hell lot of searching still I am not able to do that in Spring AMQP. Can someone please tell me how to do x-delay in Spring AMQP.
I want to Delay a message if some exception occurs in the consumer side. RabbitMQ says to add x-delay and install the plugin which I have already done, but still messages is comming immediately without any delay
I am getting this in message
Received <(Body:'[B@60a4ae5f(byte[26])'MessageProperties [headers={x-delay=15000}
@Bean
ConnectionFactory connectionFactory(){
CachingConnectionFactory connectionFactory=new CachingConnectionFactory("127.0.0.1");
connectionFactory.setUsername("guest");
connectionFactory.setPassword("guest");
connectionFactory.setPort(1500);
connectionFactory.setPublisherReturns(true);
return connectionFactory;
}
@Bean
Binding binding(@Qualifier("queue")Queue queue, DirectExchange exchange) {
return new Binding(queue.getName(), Binding.DestinationType.QUEUE, exchange.getName(), queue.getName(), null);
//return BindingBuilder.bind(queue).to(exchange).with(queueName);
}
@Bean
DirectExchange exchange() {
DirectExchange exchange=new DirectExchange("delay-exchange");
return exchange;
}
Consumer---
@Override
public void onMessage(Message message, Channel channel) throws Exception {
System.out.println("Received <" + message+ ">" +rabbitTemplate);
if(i==1){
AMQP.BasicProperties.Builder props = new AMQP.BasicProperties.Builder();
Map<String,Object> headers = message.getMessageProperties().getHeaders();
headers.put("x-delay", 15000);
props.headers(headers);
i++;
channel.basicPublish(message.getMessageProperties().getReceivedExchange(), message.getMessageProperties().getReceivedRoutingKey(),
props.build(), message.getBody());
}
}

tag, but that isn't correct. That is only about RabbitMQ. And yes,spring-amqp
