Kaka Producer is not retrying in Spring Boot Application

I am trying to test re-try Exception property of Kafka Producer in case of transient error. But it is not retrying. I read somewhere that the ProducerConfig.RETRIES_CONFIG configuration in Kafka works regardless of whether you catch exceptions or not. So I am not sure why it is not retrying?

@Beanpublic Map<String, Object> producerConfigs() {    Map<String, Object> props = new HashMap<>();    props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootStrapServers);    props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);    props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);    //Records will be failed if they can’t be delivered in delivery.timeout.ms    props.put(ProducerConfig.DELIVERY_TIMEOUT_MS_CONFIG,"120000");    // Only retry after one second.    props.put(ProducerConfig.RETRY_BACKOFF_MS_CONFIG, "1000");    // Set the number of retries     props.put(ProducerConfig.RETRIES_CONFIG, "3");    return props;}public void pushMessageToKafka(Product product) {    try {        String payload= objectMapper.writeValueAsString(product);        if(!checkIfTopicExists("product-unknown-kafka-topic")) {            throw new TimeoutException("Failed to send message to Kafka topic" );        }        ProducerRecord<String, String> producerRecord = new ProducerRecord<String, String>(productTopic,                null, product.getProductName(), payload);        ListenableFuture<SendResult<String, String>> future = kafkaTemplate.send(producerRecord);                future.addCallback(new KafkaSendCallback<String, String>() {            @Override            public void onFailure(KafkaProducerException ex) {                log.error("Failed to send product to kafka for productName:{}", product.getProductName());            }            @Override            public void onSuccess(SendResult<String, String> result) {                String topic = result.getProducerRecord().topic();                log.info("Sucsessfully send product details to kafka for productName:{} topic:{}", product.getProductName(),topic);            }        });    } catch (Exception e) {        log.error("Exception occured while trying to send product to kafka for productName:{} error:{}",                product.getProductName(), e.getMessage());    }}
