Description
In what version(s) of Spring for Apache Kafka are you seeing this issue?
3.2.0
Describe the bug
When using the @RetryableTopic annotation on a Listener that returns a CompletableFuture, no retry or dlt events are sent when the CompletableFuture completes with an exception.
To Reproduce
@RetryableTopic(
attempts = "5",
kafkaTemplate = "retryTemplate",
autoCreateTopics = "false",
backoff = @Backoff(delay = 6000)
)
@KafkaListener(
topics = "my-test-topic",
properties = {
"key.deserializer=io.confluent.kafka.serializers.KafkaAvroDeserializer",
"value.deserializer=io.confluent.kafka.serializers.KafkaAvroDeserializer",
"specific.avro.reader=true"
},
id = "myId"
)
public CompletableFuture<Void> receive(ConsumerRecord<Key, Value> record) {
log.info("Received request (id {}) on topic {}", record.key().getId(), record.topic());
CompletableFuture<Void> result = processor.process(record.key(), record.value());
result.whenComplete((v, ex) -> {
if (ex != null) {
log.error("Error processing request: {}", ex.getMessage());
}
});
return result;
}
Expected behavior
A CompletableFuture, which results in an exception, should be retried with the given properties and marked for ack on my-topic.
