springReact式kafka接收器总是覆盖引导服务器到localhost

我正在尝试使用@enablekafka和@kafkalistener注解为React式kafka消费者编写spring引导应用程序。我已经在不同的机器上配置了我的Kafka代理。当我将引导服务器提供给kafka代理的播发主机时,它总是将播发主机的ip地址覆盖到localhost。下面是我的代码。
pom.xml文件file:-

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
</dependency>
<dependency>
    <groupId>io.projectreactor.kafka</groupId>
    <artifactId>reactor-kafka</artifactId>
    <version>1.0.0.RELEASE</version>
</dependency>

config:-

@Configuration
@EnableKafka
public class AppConfig {

    @Bean
    Map consumerProps() {
        Map<String, Object> props = new HashMap<>();
        props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "192.12.12.24:9092,192.14.14.28:9092");
        props.put(ConsumerConfig.GROUP_ID_CONFIG, "example-group");
        props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
        props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, "100");
        props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "15000");
        props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG,StringDeserializer.class);
        props.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
        return props;
    }

    @Bean
    ReceiverOptions receiverOptions() {

        ReceiverOptions receiverOptions = ReceiverOptions.create(consumerProps()).subscription(Arrays.asList("hellochange"));

        return receiverOptions;
    }

    @Bean
    public KafkaReceiver kafkaReceiver() {
        return KafkaReceiver.create(receiverOptions());
    }

}

consumer:-

@Service
public class ChangeListener {

    @Autowired
    KafkaReceiver kafkaReceiver;

    @KafkaListener(topics="hellochange",groupId="example-group")
    public void receiver() {
        kafkaReceiver.receive().subscribe(System.out::println);
    }

}

console:-

auto.commit.interval.ms = 5000
    auto.offset.reset = latest
    bootstrap.servers = [localhost:9092]
    check.crcs = true
    client.id = 
    connections.max.idle.ms = 540000
    enable.auto.commit = true
2018-06-07 19:59:17.640  WARN 23536 --- [ntainer#0-0-C-1] org.apache.kafka.clients.NetworkClient   : [Consumer clientId=consumer-1, groupId=example-group] Connection to node -1 could not be established. Broker may not be available.

我已经在一个简单的消费者和非React性SpringKafka中验证了没有Spring配置的情况,对于这两种情况,它都工作得很好。只有React堆Kafka与启用Kafka和Kafka利塞纳注解我得到这个问题。
我是不是错过了什么/做错了什么?我们可以在springboot中对reactor kafka使用enablekafka和kafkalistener注解吗?
p、 我明白了, @EnableKafka 以及 @KafkaListener 如果我移除 spring-kafka 在pom.xml中,两个注解都不可用。
就像 @EnableKafka 以及 @KafkaListener 对于非React性kafka,是否有任何注解可用于配置spring引导应用程序的React性kafka消费者?

不能将kafkalistener注解用于reactor kafka; @KafkaListener 不是被动的。
