【中文标题】Spring Boot Kafka:由于 NoSuchBeanDefinitionException 而无法启动消费者【英文标题】:Spring Boot Kafka: Unable to start consumer due to NoSuchBeanDefinitionException 【发布时间】:2017-08-16 13:12:12 【问题描述】:在我的 Spring Boot 服务中尝试启动 kafka 消费者看到 NoSuchBeanDefinitionException 并且无法启动服务本身。
下面是我的 bean 类,其中包含为 Kafka 配置创建的所有必需 bean
Spring Boot 版本: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;
这是异常跟踪:
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.
【问题讨论】:
【参考方案1】:将您的 kafkaListenerContainerFactory1
bean 名称更改为 kafkaListenerContainerFactory
。
自动配置工厂正在寻找与您的不匹配的ConsumerFactory<Object, Object>
,它是
@ConditionalOnMissingBean(name = "kafkaListenerContainerFactory")
而消费者工厂是......
@ConditionalOnMissingBean(ConsumerFactory.class)
public ConsumerFactory<?, ?> kafkaConsumerFactory()
或者,禁用 Kafka 自动配置。
【讨论】:
我有相同的 pb,我想禁用自动配置,但仍然使用 @EnableConfigurationProperties(KafkaProperties.class)。我在一个 jar 中使用 Kafka Spring,其他 Spring Boot 应用程序将使用它。那么如何在我的 jar 以及依赖它的任何 Spring Boot 应用程序中禁用自动配置? 您应该提出一个新问题,而不是评论这个问题 - 这是一个不同的问题。您可以在@SpringBootApplication
注解中排除特定的自动配置类。
感谢您的回答。我发布了一个新问题:***.com/questions/43633263/…
FWIIW,自从v2.3.0.RELEASE
以来,这应该不再需要了。由github.com/spring-projects/spring-boot/issues/19221 修复【参考方案2】:
1、KafkaListener配置
@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设置
@KafkaListener(topics = KafkaTopicChannel.INPUT_CHANNEL, containerFactory = "kafkaListenerContainerFactory")
public void listen(List<ConsumerRecord<String, String>> list)
logger.debug(String.valueOf(list.size()));
