org.Apache.kafka.common.KafkaException：構築に失敗しましたkafka consumer

Question

Zookeeperを手動で起動してから、Kafka server、最後にそれぞれのプロパティファイルを使用してKafka-Restサーバーを起動します。次に、TomcatにSpring Bootアプリケーションをデプロイします

Tomcatログトレースで、エラーorg.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is org.Apache.kafka.common.KafkaException: Failed to construct kafka consumerが表示され、アプリケーションの起動に失敗します

############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.

ReceiverクラスとSenderクラスには、@Componentや@Serviceなどの注釈が付いていません。違いはありますか？

@Configuration 
public class InventorySenderConfig

@Configuration 
@EnableKafka 
public class InventoryReceiverConfig

@Component 
public class KafkaConfig

@Configuration 
public class ProducingChannelConfig

@Configuration 
public class ConsumingChannelConfig

@RestController 
public class KafkaWebhookController

@Service("webhookService") 
public class KafkaServiceImpl

@EnableIntegration 
@SpringBootApplication 
@ComponentScan("com.psl.kafka") 
public class SpringKafkaWebhookServiceApplication extends SpringBootServletInitializer

これらは私のクラス注釈です。彼らは大丈夫に見えるか、何かを変更する必要がありますか？

ProducingChannelConfig、ConsumingChannelConfig、InventoryReceiverConfigクラスで構成として追加したInterceptorクラスを定義する必要がありますか？

Answer 1

原因：Java.lang.ClassNotFoundException：org.Apache.kafka.common.ClusterResourceListener

クラスパスにkafka-clients jarがありません。依存関係管理に何を使用していますか？ Mavenとgradleは、このjarを自動的にクラスパスに配置する必要があります。

Answer 2

あなたのkafkaバージョンは本来より古く、問題のあるクラス ClusterResourceListener バージョンは0.10.1.0よりも高く、バージョンは0.10.1。

kafka= jarをアップグレードするだけで、この問題は修正されます。

各メタデータの応答後に、onUpdate（ClusterResource）が1回呼び出されます。 Kafkaブローカーのバージョンが0.10.1.0未満の場合、クラスターIDはnullになる場合があります。
