spring-cloud-stream-binder-rabbit | Spring Cloud Stream Binder implementation for Rabbit | Microservice library

I'm using
spring-cloud-stream : 3.1.4
spring-cloud-stream-binder-rabbit: 3.1.4

I have a consumer configured with the here under properties. My issue is when consumer starts before the rabbitmq server is available i can see that the consumer restarts until the connexion is available. Nevertheless the created binding between DLX and DLQ is not the same.

• If rabbitmq is available when consumer starts : DLQ is bind to DLX with both routing key 'worker.request.queue.name' and 'worker.request.dlq.name'
• If rabbitmq is not available when consumer starts after some retries : DLQ is only bind to DLX with the routingKey 'worker.request.dlq.name'.

The issue is that i need both binding. Anyone can help me understand what am i doing wrong ?

Thanks.

When I got message from queue and if exception was thrown, I want to get message again. So, I create my consumer with dql queue:

I am trying to achieve the above scenario using spring cloud stream supplier and consumer.

1. This app is a single spring boot app containing producer and consumer.
2. There is one producer and (can be) multiple consumers. All consumers should behave as a client to queue (i.e. single message should be received by a single consumer only) and other consumers receive different messages.

Below is the java class

I use the 3.1.3 version. After the following configuration,'output-out-0.producer.bindingRoutingKey' does not take effect. When I send a message, Routing keys = command_exchange_open instead of: ORDER_PUSH

I added every gradle dependency which required for my project but I am getting Unresolved reference: log issue when use log.info() Here below my codes

I've got a working application that listens to a single RabbitMQ queue.

However, when I add another bean that consumes messages and try to bind that to another queue, neither of the queues are created in RabbitMQ and when creating them manually no messages are consumed from these queues.

Small kotlin project I created to demonstrate the issue:

I have a Spring Cloud Stream application that receives messages from RabbitMQ using the Rabbit Binder, update my database and send one or many messages. My application can be summarized as this demo app:

The problem is that it doesn't seem that @Transactional works(or at least that's my impression) since if there's an exception the Database is rollbacked but messages are sent even the consumer/producer are configured by default as transacted.

Given that what I want to achieve is when an exception occurs I want the consumed messages go to DLQ after being retried the Database is rolled back and messages are not sent.

How can I achieve this?

This is the output of the demo application when I send a message my-input exchange

So, I've been trying to start a migration from Maven to Gradle at my work but I've now run into a serious problem which I can't seem to wrap my head around.

I basically just wanna run some simple liquibase migrations for my tests, for which I spin up two testcontainers. One for a rabbitmqexchange and one for a postgres DB.

I've set up the postgres container using a little workaround described here: Testing Spring Boot Applications with Kotlin and Testcontainers

I've tried it a thousand ways and scoured all related questions but I can't seem to figure out what the problem is...

Here is the setup using Gradle 6.7.1:

I want to send messages to a rabbitmq queue demo-queue using a very simple spring boot app:
