Spring Boot Kafka: Unable to start consumer due to NoSuchBeanDefinitionException
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.
1、KafkaListener Configuration
@Configuration
@EnableKafka
public class KafkaListenerConfiguration {
@Autowired
private Environment environment;
@Bean
public KafkaListenerContainerFactory<?> kafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory());
factory.setBatchListener(true);
return factory;
}
@Bean
public ConsumerFactory<String, String> consumerFactory() {
return new DefaultKafkaConsumerFactory<>(consumerConfigs());
}
@Bean
public Map<String, Object> consumerConfigs() {
Map<String, Object> props = new HashMap<>();
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, environment.getProperty("spring.kafka.bootstrap-servers"));
props.put(ConsumerConfig.GROUP_ID_CONFIG, "1111");
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, "org.apache.kafka.common.serialization.StringDeserializer");
return props;
}
}
2、KafkaListener Setting
@KafkaListener(topics = {KafkaTopicChannel.INPUT_CHANNEL}, containerFactory = "kafkaListenerContainerFactory")
public void listen(List<ConsumerRecord<String, String>> list) {
logger.debug(String.valueOf(list.size()));
}
