에 카프카 버전 업데이트 후

새로운 빌드 오류 내가 ProducingChannelConfig, ConsumingChannelConfig의 설정뿐만 아니라 InventoryReceiverConfig 클래스로 추가 한 인터셉터 클래스를 정의해야합니까?

Answer 1

귀하의 카프카 버전이 이전 버전보다 오래되었습니다. 문제가되는 클래스 ClusterResourceListener은 버전이 0.10.1.0 이상이고 버전이 0.10.0.1보다 낮을 것으로 예상합니다.

카프카 항아리를 업그레이드하면 문제가 해결됩니다.

각 메타 데이터 응답 후에 onUpdate (ClusterResource)가 한 번 호출됩니다. Kafka 브로커 버전이 0.10.1.0 이하인 경우 클러스터 ID가 null 일 수 있습니다.

Answer 2

발생 원인 : java.lang.ClassNotFoundException : org.apache.kafka.common.ClusterResourceListener

클래스 경로에서 kafka-clients 병이 없습니다. 의존성 관리를 위해 당신은 무엇을 사용하고 있습니까? 메이븐 (Maven)과 그레블 (gradle)은 자동으로이 항아리를 클래스 경로에 놓아야합니다.
