Class ByteArrayJacksonJsonMessageConverter

java.lang.Object

org.springframework.kafka.support.converter.MessagingMessageConverter

org.springframework.kafka.support.converter.JacksonJsonMessageConverter

org.springframework.kafka.support.converter.ByteArrayJacksonJsonMessageConverter

All Implemented Interfaces:

MessageConverter, RecordMessageConverter

public class ByteArrayJacksonJsonMessageConverter
extends JacksonJsonMessageConverter

JSON Message converter that uses Jackson 3 - byte[] on output, String, Bytes, or byte[] on input. Used in conjunction with Kafka ByteArraySerializer/(ByteArrayDeserializer, BytesDeserializer, or StringDeserializer). More efficient than StringJacksonJsonMessageConverter because the String<->byte[] conversion is avoided.

4.0
