無法創建卡夫卡消費者

我正在使用spring-kafka，並且正在嘗試創建卡夫卡消費者。我已參考http://howtoprogram.xyz/2016/09/23/spring-kafka-tutorial/ 和https://www.codenotfound.com/2016/09/spring-kafka-consumer-producer-example.html。我目前使用的是完全相同的代碼。無法創建卡夫卡消費者

這裏是Receiver類

public class Receiver { 

private static final Logger LOGGER = LoggerFactory.getLogger(Receiver.class); 
public final CountDownLatch countDownLatch1 = new CountDownLatch(1); 

@KafkaListener(id = "foo", topics = "HelloKafkaTopic", group = "group1") 
public void receive(ConsumerRecord<?, ?> record) { 
    System.out.println(record); 
    countDownLatch1.countDown(); 
} 
}

這裏是KafkaConsumerConfig

@Configuration 
@EnableKafka 
public class KafkaConsumerConfig { 
@Bean 
KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String, String>> kafkaListenerContainerFactory() { 
    ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>(); 
    factory.setConsumerFactory(consumerFactory()); 
    factory.setConcurrency(3); 
    factory.getContainerProperties().setPollTimeout(3000); 
    return factory; 
} 

@Bean 
public ConsumerFactory<String, String> consumerFactory() { 
    return new DefaultKafkaConsumerFactory<>(consumerConfigs()); 
} 

@Bean 
public Map<String, Object> consumerConfigs() { 
    Map<String, Object> propsMap = new HashMap<>(); 
    propsMap.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092"); 
    propsMap.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false); 
    propsMap.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, "100"); 
    propsMap.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "15000"); 
    propsMap.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class); 
    propsMap.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class); 
    propsMap.put(ConsumerConfig.GROUP_ID_CONFIG, "group1"); 
    propsMap.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest"); 
    return propsMap; 
} 

@Bean 
public Receiver listener() { 
    return new Receiver(); 
}

當我註釋我的類，它有@KafkaListener法，用@EnableKafka。我收到以下錯誤。如果我在某個地方犯了錯，我很難理解。

我認爲問題出在你的classpath中，你的老版本是spring-messaging。嘗試運行使用依賴管理&修復spring-messaging的最新（v4.3.x）版本pom.xml。

首先檢查您目前正在使用哪個版本的spring-messaging？

我使用gradle構建我的項目。我正在使用org.springframework：spring-messaging：4.2.6-RELEASE –

將它更新到4.3.x（無論最新版本是否可用） –

是的，我想到了，感謝您的幫助 –
