Java Spring集成Kafka ClassNotFoundException:KafkaHeaderMapper

使用Spring integration kafka库运行Spring引导应用程序时，我遇到以下错误：

原因：java.lang.ClassNotFoundException:org.springframework.kafka.support.KafkaHeaderMapper

在以下方法主体的第一行引发异常：

@ServiceActivator(inputChannel = "producerChannel")
public MessageHandler kafkaMessageHandler() {
    KafkaProducerMessageHandler<String, String> handler =
        new KafkaProducerMessageHandler<>(kafkaTemplate());
    handler.setMessageKeyExpression(new LiteralExpression("kafka-integration"));

    return handler;
}

@ServiceActivator（inputChannel=“producerChannel”）
public MessageHandler kafkaMessageHandler（）{
KafkaProducerMessageHandler处理器=
新的KafkaProducerMessageHandler（kafkaTemplate（））；
setMessageKeyExpression（新的LiteralExpression（“kafka集成”）；
返回处理程序；
}

我的pom.xml是：

我遗漏了什么？

请参阅

Spring集成Kafka 2.3.x需要Spring Kafka 1.3.x版

Boot 1.5.x默认拉入1.1.x

将

1.3.2.RELEASE

添加到spring kafka依赖项中
