spring-retry | Example use spring-retry project

I am new to springboot and trying to upgrade from 2.3.8.RELEASE to 2.4.0 and my test cases are failing. I am getting these error:

In my application config i have defined the following properties:

Here is the Spring repo that was used as a reference (same happenned to my project): https://github.com/spring-guides/gs-centralized-configuration.git

I am new to spring-retry. Basically, for retrying calls to REST APIs, I have integrated spring-retry into my spring-boot application. To do this, I have made following changes:

1. Added spring-retry to pom.xml.

2. Added following configuration:

   ...

I am using spring-retry with configurations loaded from https://launchdarkly.com/. We have this feature flag service where I can change configurations like maxAttempts and interval from the feature flag. However, spring-retry doesn't react to it. Is there any way to detect these new configurations?

Following is the example:

This is retry method:

How to pack the executable jar in zip using maven-assembly-plugin and not the Original file i.e. .jar.original

Currently, on providing maven-assembly-plugin as dependency, it packs the jar.original in the zip.

I am using spring-amqp consumerBatchEnabled to process messages in batch. and for error handling and retry, using Dead letter exchange with spring-retry backoff with recoverer functionality.

If there is any exeception during processing of batch in the main queue I am rejecting the entire batch and then messages are processed individually by Dead letter queue listener. I have configured Advice chain for DLQ listener for retries. Idea is to have fixed number of retries in DLQ listener before discarding the message.

Retry functionality works fine and recoverer is also invoked but message remains in unack state in dead letter queue. As per my understanding message should either be dropped from the queue in case of AmqpRejectAndDontRequeueException, but it does not seem to be happening, Am I missing something here. (This also does not work if I attached DLX)

(With default listener container factory and retry properties in application.yml this works as expected but not with custom listenercontainerfactory)

Below is the test code:

I am trying to set up a RetryTemplate in Spring Batch, I just cannot find an example on how to add the RetryTemplate into the StepBuilderFactory. I've found this example to set it up in a SpringBoot Application, https://dzone.com/articles/how-to-use-spring-retry-template but no luck on Spring Batch.

The reason I am trying to use RetryTemplate is to set-up a Exponential BackOffPolicy (Spring Batch how to configure retry period for failed jobs).

I imagine to wire the RetryTemplate would be as simple as setting the RetryTemplate Bean, something like it (modified code from @Mahmoud Ben Hassine answer Spring Batch how to configure retry period for failed jobs):

I'm currently working on a microservices application for my internship using Consul for service discovery and feign clients for communicating between the services. When we started working on the existing project which already was built using microservices, we upgraded Spring boot to 2.4.3 & cloud to 2020.0.1, so that we could make use of Java 15 to use records instead of normal classes for dtos. The problem we have now is that, whenever we make a call to a composite service, that will try to retrieve data from multiple services (for example users and teams service), that we get the following stacktrace:
