Spring Boot Kafka：NoSuchBeanDefinitionExceptionのためにコンシューマーを開始できません

Question

私の春のブートサービスで、NoSuchBeanDefinitionExceptionを見て、サービス自体を開始できないkafkaコンシューマーを開始しようとしています。以下は

カフカ構成

春ブートバージョン用に作成されたすべての必要な豆持っている私のBeanクラスである：ここで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; 
} 


}

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. 

を

Answer 1

kafkaListenerContainerFactory1のBean名をkafkaListenerContainerFactoryに変更してください。

自動設定工場があなたのものと一致しないConsumerFactory<Object, Object>を探していると消費者の工場が...

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

あるいは、カフカの自動設定を無効にしているのに対し、それは

@ConditionalOnMissingBean(name = "kafkaListenerContainerFactory") 

です。

Answer 2

1、KafkaListener設定

@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は、KafkaListenerは

@KafkaListener(topics = {KafkaTopicChannel.INPUT_CHANNEL}, containerFactory = "kafkaListenerContainerFactory") 
public void listen(List<ConsumerRecord<String, String>> list) { 
    logger.debug(String.valueOf(list.size())); 
}
