为 KafkaListener 编写测试

Question

我在应用程序中配置了一个监听器

    @KafkaListener(topics = TOPIC)
    public void messageListener(ConsumerRecord<String, String> consumerRecord, Acknowledgment ack) {
        String payload = consumerRecord.value();
        Map<String, Object> headers = TopicUtil.getHeaderHashMap(consumerRecord);
        String mHeader = getFileNameWithoutTimeStampAndExtension(headers.get("mHeader").toString());
    }

import org.apache.kafka.clients.consumer.ConsumerRecord;

import java.util.HashMap;
import java.util.Map;

public class TopicUtil {
    public static Map<String, Object> getHeaderHashMap(ConsumerRecord<String, String> consumerRecord) {
       Map<String,Object> headers = new HashMap<>();
        consumerRecord.headers().iterator().forEachRemaining(header -> {
            headers.put(header.key(), new String(header.value()));
        });
        return headers;
    }
}

我正在尝试测试侦听器

this.kafkaTemplate.send(inputTopic,record);

因为参数不匹配所以抛出错误

org.springframework.kafka.listener.ListenerExecutionFailedException: Listener method 'public void com.saif.configurations.Myconfig.messageListener(org.apache.kafka.clients.consumer.ConsumerRecord<java.lang.String, java.lang.String>,org.springframework.kafka.support.Acknowledgment)' threw exception; nested exception is java.lang.ClassCastException: class org.springframework.kafka.listener.KafkaMessageListenerContainer$ListenerConsumer$ConsumerAcknowledgment cannot be cast to class java.util.Map (org.springframework.kafka.listener.KafkaMessageListenerContainer$ListenerConsumer$ConsumerAcknowledgment is in unnamed module of loader 'app'; java.util.Map is in module java.base of loader 'bootstrap'); nested exception is java.lang.ClassCastException: class org.springframework.kafka.listener.KafkaMessageListenerContainer$ListenerConsumer$ConsumerAcknowledgment cannot be cast to class java.util.Map (org.springframework.kafka.listener.KafkaMessageListenerContainer$ListenerConsumer$ConsumerAcknowledgment is in unnamed module of loader 'app'; java.util.Map is in module java.base of loader 'bootstrap')

任何方式来实现这一点，我需要我的记录有标题，还需要发送确认
