Kafka Spring and multiple kafkaListenerContainerFactory
I have the following Kafka Spring consumer configuration:
@Configuration
public class KafkaConsumerTestConfig {
@Value("${spring.kafka.bootstrap-servers}")
private String bootstrapServers;
@Value("${spring.kafka.consumer.group-id}")
private String consumerGroupId;
@Bean
public Map<String, Object> consumerConfigs() {
Map<String, Object> props = new HashMap<>();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
props.put(ConsumerConfig.GROUP_ID_CONFIG, consumerGroupId);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class);
return props;
}
@Bean
public ConsumerFactory<String, ImportDecisionMessage> consumerFactory() {
return new DefaultKafkaConsumerFactory<>(consumerConfigs(), new StringDeserializer(), new JsonDeserializer<>(ImportDecisionMessage.class));
}
@Bean
public ConcurrentKafkaListenerContainerFactory<String, ImportDecisionMessage> kafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, ImportDecisionMessage> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory());
return factory;
}
}
So far everything works well.
Now, I'd like another type of message, let's say Review. I change my configuration to the following one:
@Configuration
public class KafkaConsumerTestConfig {
@Value("${spring.kafka.bootstrap-servers}")
private String bootstrapServers;
@Value("${spring.kafka.consumer.group-id}")
private String consumerGroupId;
@Bean
public Map<String, Object> consumerConfigs() {
Map<String, Object> props = new HashMap<>();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
props.put(ConsumerConfig.GROUP_ID_CONFIG, consumerGroupId);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, JsonDeserializer.class);
return props;
}
@Bean
public ConsumerFactory<String, ImportDecisionMessage> importDecisionMessageConsumerFactory() {
return new DefaultKafkaConsumerFactory<>(consumerConfigs(), new StringDeserializer(), new JsonDeserializer<>(ImportDecisionMessage.class));
}
@Bean
public ConcurrentKafkaListenerContainerFactory<String, ImportDecisionMessage> importDecisionMessageKafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, ImportDecisionMessage> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(importDecisionMessageConsumerFactory());
return factory;
}
@Bean
public ConsumerFactory<String, Review> reviewConsumerFactory() {
return new DefaultKafkaConsumerFactory<>(consumerConfigs(), new StringDeserializer(), new JsonDeserializer<>(Review.class));
}
@Bean
public ConcurrentKafkaListenerContainerFactory<String, Review> reviewKafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, Review> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(reviewConsumerFactory());
return factory;
}
}
and my Spring Boot application fails with the following exception:
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 beans of type'org.springframework.kafka.core.ConsumerFactory'importDecisionMessageConsumerFactory
Action:
Consider revisiting the conditions above or defining a bean of type 'org.springframework.kafka.core.ConsumerFactory' in your configuration.

What am I doing wrong and how to fix it ? Why do I need to configure this default kafkaListenerContainerFactory ? Is it possible to avoid it?

You can exclude KafkaAutoConfiguration from you Spring Boot configuration. Or call one of the KafkaListenerContainerFactory with the proper bean name to satisfy the condition:
@ConditionalOnMissingBean(name = "kafkaListenerContainerFactory")
