如何在Spring Cloud Stream Kafka Binder中设置死信队列的保留时间？

spring:
  cloud:
    stream:
      kafka:
        binder:
          configuration:
            # 设置死信队列的保留时间，单位为毫秒
            x-dead-letter-queue-ttl: 60000

@Configuration
@ConfigurationProperties(prefix = "spring.cloud.stream.kafka.binder")
public class KafkaBinderConfiguration {

    private Map<String, String> configuration;

    public Map<String, String> getConfiguration() {
        return configuration;
    }

    public void setConfiguration(Map<String, String> configuration) {
        this.configuration = configuration;
    }

    @Bean
    public KafkaBinderHealthIndicator kafkaBinderHealthIndicator(KafkaBinderConfiguration configuration) {
        KafkaBinderHealthIndicator healthIndicator = new KafkaBinderHealthIndicator();
        // 从配置中获取死信队列的保留时间，并设置到健康指示器中
        String deadLetterQueueTtl = configuration.get("configuration.x-dead-letter-queue-ttl");
        healthIndicator.setDeadLetterQueueTtl(deadLetterQueueTtl);
        return healthIndicator;
    }
}
