Class RetryTopicConfigurationProvider

java.lang.Object

org.springframework.kafka.annotation.RetryTopicConfigurationProvider

public class RetryTopicConfigurationProvider
extends Object

Attempts to provide an instance of RetryTopicConfiguration by either creating one from a RetryableTopic annotation, or from the bean container if no annotation is available.

If beans are found in the container there's a check to determine whether or not the provided topics should be handled by any of such instances.

If the annotation is provided, a DltHandler annotated method is looked up.
