Configure Kafka consumer acknowledgement mode for Spring Boot Kafka project

Question

I'm using Spring Boot version 1.5.2.RELEASE along with Spring Kafka version 1.1.2.RELEASE. Via the application.properties file I do see available options (spring.kafka.consumer.*) to configure Kafka Consumer.

What I'm not able to find though is a way to configure the acknowledgement mode.

Answer 1

spring.kafka.listener.ack-mode=

Answer 2

You can use Spring Cloud Stream Kafka Binder to streaming messages. In that case

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-stream-binder-kafka</artifactId>
</dependency>

and configure consumer like this.

spring.cloud.stream.kafka.bindings.<channelName>.consumer..

and producer like this

spring.cloud.stream.kafka.bindings.<channelName>.producer..
