Spring Boot Kafka: Unable to start consumer due to NoSuchBeanDefinitionException

Question

With in my spring boot service while trying to start a kafka consumer seeing NoSuchBeanDefinitionException and unable to start the service itself.

Below is my bean class which has all the required beans created for Kafka configuration

Spring Boot Version: 1.5.2.RELEASE

import java.util.HashMap;
import java.util.Map;

import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.common.serialization.Deserializer;
import org.apache.kafka.common.serialization.StringDeserializer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.kafka.annotation.EnableKafka;
import org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory;
import org.springframework.kafka.core.ConsumerFactory;
import org.springframework.kafka.core.DefaultKafkaConsumerFactory;
import org.springframework.kafka.support.serializer.JsonDeserializer;

import com.ns.kafka.gateway.dtos.GatewayCallBackMessage;

@Configuration
@EnableKafka
public class GatewayCallbackToPNConsumerConfig {
 @Bean
 public Map < String, Object > consumerProps() {
  Map < String, Object > props = new HashMap < > ();
  props.put(null, null);
  props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
  props.put(ConsumerConfig.GROUP_ID_CONFIG, "gatewaycallbacktopngroup");
  props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
  props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, "100");
  props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "15000");
  return props;
 }

 @Bean
 public Deserializer < String > stringKeyDeserializer() {
  return new StringDeserializer();
 }

 @Bean
 public Deserializer < GatewayCallBackMessage > gatewayCallBackMessageJsonValueDeserializer() {
  return new JsonDeserializer < GatewayCallBackMessage > (GatewayCallBackMessage.class);
 }

 @Bean
 public ConsumerFactory < String, GatewayCallBackMessage > consumerFactory() {
  return new DefaultKafkaConsumerFactory < > (consumerProps(),
   stringKeyDeserializer(), gatewayCallBackMessageJsonValueDeserializer());
 }


 @Bean
 public ConcurrentKafkaListenerContainerFactory < String, GatewayCallBackMessage > kafkaListenerContainerFactory1() {
  ConcurrentKafkaListenerContainerFactory < String, GatewayCallBackMessage > factory = new ConcurrentKafkaListenerContainerFactory < > ();


  factory.setConcurrency(1);
  factory.setConsumerFactory(consumerFactory());
  return factory;
 }


}

Here is the exception trace:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.kafka.core.ConsumerFactory<java.lang.Object, java.lang.Object>' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Description:

Parameter 1 of method kafkaListenerContainerFactory in org.springframework.boot.autoconfigure.kafka.KafkaAnnotationDrivenConfiguration required a bean of type 'org.springframework.kafka.core.ConsumerFactory' that could not be found.
    - Bean method 'kafkaConsumerFactory' in 'KafkaAutoConfiguration' not loaded because @ConditionalOnMissingBean (types: org.springframework.kafka.core.ConsumerFactory; SearchStrategy: all) found bean 'consumerFactory'


Action:

Consider revisiting the conditions above or defining a bean of type 'org.springframework.kafka.core.ConsumerFactory' in your configuration.

Answer 1

Change your kafkaListenerContainerFactory1 bean name to kafkaListenerContainerFactory.

The auto config factory is looking for a ConsumerFactory<Object, Object> which doesn't match yours and it is

@ConditionalOnMissingBean(name = "kafkaListenerContainerFactory")

Whereas the consumer factory is...

@ConditionalOnMissingBean(ConsumerFactory.class)
public ConsumerFactory<?, ?> kafkaConsumerFactory() {

Or, disable Kafka auto configuration.
