Spring Kafka Producer not sending to Kafka 1.0.0 (Magic v1 does not support record headers)

Question

I am using this docker-compose setup for setting up Kafka locally: https://github.com/wurstmeister/kafka-docker/

docker-compose up works fine, creating topi

Answer 1

you are using kafka version <=0.10.x.x once you using using this, you must set JsonSerializer.ADD_TYPE_INFO_HEADERS to false as below.

Map props = new HashMap<>(defaultSettings);
props.put(JsonSerializer.ADD_TYPE_INFO_HEADERS, false);
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, JsonSerializer.class);
ProducerFactory producerFactory = new DefaultKafkaProducerFactory<>(props);

for your producer factory properties.

In case you are using kafka version > 0.10.x.x, it should just work fine
