, 나는 다음과 같은 오류를 얻고있다 봄 - 통합 - 카프카 라이브러리는 봄 부팅 응용 프로그램을 실행하는 동안 :봄 통합 카프카의 ClassNotFoundException : KafkaHeaderMapper
예외는 본문의 첫 번째 줄에서 발생합니다Caused by: java.lang.ClassNotFoundException: org.springframework.kafka.support.KafkaHeaderMapper
다음과 같은 방법

handler.setMessageKeyExpression(new LiteralExpression("kafka-integration"));
return handler;
}
