如何在不了解Avro模式的情况下在scala中读取avro编码的kafka消息？

<dependency>

import org.apache.kafka.clients.consumer.{ConsumerConfig, KafkaConsumer}

props.put("schema.registry.url", "http://schema-registry:8081")

val consumer = new KafkaConsumer[String, GenericRecord](props)

import org.apache.avro.generic.GenericRecord

consumer.subscribe(Collections.singletonList("topic-name"))

while (true) {
    val records = consumer.poll(Duration.ofMillis(100))
    for (record <- records.asScala) {
        val avroRecord = record.value() // 获取Avro编码的消息
        // 在这里可以对Avro消息进行处理
    }
}
