Add the overloaded methods to build producer / consumer properties from KafkaProperties

[kitkars]

This request is related to 39144.

We used to have below methods in the KafkaProperties class.

buildProducerProperties()
buildConsumerProperties()

Looks like they have been removed / modified to accept SslBundles from 3.4.

buildProducerProperties(SslBundles sslBundles)
buildConsumerProperties(SslBundles sslBundles)

The Reactive Kafka Producer / Consumer Template classes have an option to accept the SenderOptions / ReceiverOptions as shown below. As the buildConsumerProperties requires SslBundles , I can pass null to make the code work as suggested in other thread.

    @Bean
    public ReceiverOptions<String,MyEvent> receiverOptions(KafkaProperties kafkaProperties){
        return ReceiverOptions.<String, MyEvent>create(kafkaProperties.buildConsumerProperties(null))
                .consumerProperty(JsonDeserializer.REMOVE_TYPE_INFO_HEADERS, "false")
                .consumerProperty(JsonDeserializer.USE_TYPE_INFO_HEADERS, false)
                .consumerProperty(JsonDeserializer.VALUE_DEFAULT_TYPE, MyEvent.class)
                .subscription(List.of("my-events"));
    }

    @Bean
    public ReactiveKafkaConsumerTemplate<String, MyEvent> consumerTemplate(ReceiverOptions<String, MyEvent> options){
        return new ReactiveKafkaConsumerTemplate<>(options);
    }

However, It is really convenient to have simple below overloaded method as part of the KafkaProperties class itself which calls the appropriate methods with null.

buildProducerProperties()
buildConsumerProperties()

It would be great if you consider this request.
