org.apache.kafka.common.errors.TimeoutException：60000 毫秒后元数据中不存在主题 mouTopic。 （与融合卡夫卡）

Question

我正在使用 Confluent Kafka，并且所需的主题已经存在。向 Kafka 发送数据时出现以下异常。

<块引用>

org.springframework.kafka.KafkaException：发送失败；嵌套异常是 org.apache.kafka.common.errors.TimeoutException：60000 毫秒后元数据中不存在主题 mouTopic。

Below  is my config class:

@SpringBootApplication
@EnableConfigurationProperties
@EnableKafka
public class Application {

    public static void main(final String[] args) {

        SpringApplication.run(Application.class, args);
    }

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

    @Bean
    public ProducerFactory<String, String> producerFactory() {
        Map<String, Object> configProps = new HashMap<>();
        configProps.put(
                ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,
                bootstrapServers);
        configProps.put(
                ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG,
                StringSerializer.class);
        configProps.put(
                ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,
                StringSerializer.class);
        return new DefaultKafkaProducerFactory<>(configProps);
    }

    @Bean
    public KafkaTemplate<String, String> kafkaTemplate() {
        return new KafkaTemplate<>(producerFactory());
    }

}

我的休息端点：

 @GetMapping("/sendOfferDataToKafka")
    public String allocateOffers() {
     Message<String> message = MessageBuilder
     .withPayload("data")
     .setHeader(KafkaHeaders.TOPIC, "mouTopic")
     .setHeader(KafkaHeaders.MESSAGE_KEY, "999")
     .setHeader(KafkaHeaders.PARTITION_ID, 0)
     .build();

      System.err.print("message" + message.toString());

      kafkaTemplate.send(message);

      return message.toString();
 }
