Spring Boot Kafka - Execute peice of code after reconnecting service to kafka broker - spring

Question

I'm testing kafka broker down scenarios in my service. Is there any way to execute piece of code once the service became connected again to the broker ?
For example:-
When the producer fails to send a message or throws an exception the service stores the message in a temp table to resend it once reconnecting to the broker.
#Transactional
#EventListener
public void detailsObjectEventListener(EntityObjectEvent<DetailsEntity> event) {
StreamPayload<Details> payload = new StreamPayload<>(event.getType(), new Details(event.getSource()));
MessageChannel channel = BootstrapApplication.getMessageChannel(DetailsChannel.class);
boolean sent;
try {
sent = channel.send(MessageBuilder.withPayload(payload).build());
} catch (Exception ex) {
sent = false;
}
if (!sent) {
entityManager.persist(new FailedStreamEventEntity(event));
}
}
To handle the problem i made a cron job method to republish failed events again when the broker is UP.
#Scheduled(initialDelay = 10000, cron = "0 * * * * ?")
public void reSendFailedEvents() {
if (kafkaIndicator.health().getStatus().equals(Status.UP)) {
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
Optional.of(FailedStreamEventEntity.class)
.map(builder::createQuery)
.map(query -> query.select(query.from(FailedStreamEventEntity.class)))
.map(entityManager::createQuery)
.map(TypedQuery::getResultList)
.map(List::stream)
.orElse(Stream.empty())
.peek(entityManager::remove)
.map(FailedStreamEventEntity::getEvent)
.forEach(BootstrapApplication.getEventPublisher()::publishEvent);
}
}
But, i believe its the worst solution to handle the problem. Also, i believe that there is a better way that can execute this code once the service reconnected to the broker. (Any help ?)
