ByteArrayJsonMessageConverter (Spring Kafka 2.6.8 API)

java.lang.Object
- org.springframework.kafka.support.converter.MessagingMessageConverter
- - org.springframework.kafka.support.converter.JsonMessageConverter
  - - org.springframework.kafka.support.converter.ByteArrayJsonMessageConverter

All Implemented Interfaces:

MessageConverter, RecordMessageConverter
```
public class ByteArrayJsonMessageConverter
extends JsonMessageConverter
```
JSON Message converter - byte[] on output, String, Bytes, or byte[] on input. Used in conjunction with Kafka ByteArraySerializer/(ByteArrayDeserializer, BytesDeserializer, or StringDeserializer). More efficient than StringJsonMessageConverter because the String<->byte[] conversion is avoided.

Since:

2.3
