Kafka Consumer Interceptor не регистрируется в приложении весенней загрузки ⇐ JAVA

[Anonymous]

У меня есть следующий класс потребительского перехватчика Kafka (ApiGatewayKafkaConsumerInterceptor):
package com.aman.api.gateway.kafka.interceptor;

import java.util.Map;
import org.apache.kafka.clients.consumer.ConsumerInterceptor;
import org.apache.kafka.clients.consumer.ConsumerRecords;
import org.apache.kafka.clients.consumer.OffsetAndMetadata;
import org.apache.kafka.common.TopicPartition;

public class ApiGatewayKafkaConsumerInterceptor implements ConsumerInterceptor {

public ApiGatewayKafkaConsumerInterceptor(){
System.out.println("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
System.out.println("$$$ $$$");
System.out.println("$$$ GATEWAY INTERCEPTOR REGISTERED $$$");
System.out.println("$$$ $$$");
System.out.println("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
}

@Override
public ConsumerRecords onConsume(ConsumerRecords consumerRecords) {
return consumerRecords;
}

@Override
public void onCommit(Map offsets) {
}

@Override
public void close() {
}

@Override
public void configure(Map configs) {
}

}

и следующий класс KafkaConsumerConfig:
package com.aman.api.gateway.kafka.config;

import com.aman.api.gateway.controller.switcher.TransactionController;
import com.aman.api.gateway.kafka.interceptor.ApiGatewayKafkaConsumerInterceptor;

@ConditionalOnMissingBean(name = "requestKafkaListenerContainerFactory")

Map props = consumerConfigs(ConsumerConfigType.REQUEST);
System.out.println("Creating a consumer factory with props = " + props);
return new DefaultKafkaConsumerFactory(props, new StringDeserializer(),

Хотя свойство interceptor.classes успешно передается фабрике потребителей, оно по-прежнему отображается пустым, когда Kafka отображает значения ConsumerConfig, а перехватчик не зарегистрирован. Вот результат (соответствующая часть), когда я запускаю приложение весенней загрузки:
