To configure the retry topic and dlt for a @KafkaListener annotated method, you just have to add the @RetryableTopic annotation to it and Spring for Apache Kafka will bootstrap all the necessary topics and consumers with the default configurations. This is the sample code snippet I have tried. Since 3. Whether the retry topics will be suffixed with the delay value for that topic or a simple index. Periodically, massage can't process and consumer throw exception.

In the latter the consumer ends the execution without forwarding the Then, if you are using the DeadLetterPublishingRecoverer to publish a failed record, the processor will send the recovered record’s offset in the original topic/partition to the If Kafka consumer throws an exception while processing the message, spring-retry template will be invoked. Use accessor. The global minimum number of partitions that the binder configures To enable DLQ, a Kafka binder based applications must provide a consumer group via the property spring. excludeTopics When integrating Apache Kafka with a Spring Boot application, configuring the essential Kafka properties is pivotal for seamless 在 Spring Boot 中整合 Kafka 并实现消息重试，可以使用以下几种方法：使用 Kafka 消费者配置属性实现重试：在 application. annotation, annotation type: EnableKafkaRetryTopic Figure 3: Non-blocking retry with Spring Kafka The diagram illustrates multiple retry topics in use.

Rather than retry an event from the original topic in a blocking manner, spring. annotation, annotation type: EnableKafkaRetryTopic spring. annotation, annotation type: EnableKafkaRetryTopic In the former the record is forwarded back to the DLT topic so it doesn’t block other DLT records' processing. class would retry only via blocking and, if all retries fail, would go straight to the DLT. enabled") @ConditionalOnSingleCandidate (org. 2, Spring for Apache Kafka supports non-blocking retries with @KafkaListener on a Class. enabledの解説 spring. Using more retry topics and a dead letter queue topic enabled us to retry the request without blocking the main consumer. Blocking and nonblocking retry logic.
