如何在spring kafka中通过应用程序属性设置factory.setAckDiscarded(true)？

spring.kafka.producer.properties.acks=0

@Configuration
@EnableKafka
public class KafkaConfig {

    @Value("${spring.kafka.bootstrap-servers}")
    private String bootstrapServers;

    @Bean
    public KafkaTemplate<String, String> kafkaTemplate() {
        Map<String, Object> producerProps = new HashMap<>();
        producerProps.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
        producerProps.put(ProducerConfig.ACKS_CONFIG, "0");

        DefaultKafkaProducerFactory<String, String> producerFactory = new DefaultKafkaProducerFactory<>(producerProps);
        producerFactory.setAckDiscarded(true);

        return new KafkaTemplate<>(producerFactory);
    }
}
