Kafka SpringBoot(1.5.9)およびSpring-kafka(2.1.0)を使用するコンシューマーをセットアップしようとしています。ただし、アプリを起動するとJava.lang.NoSuchMethodError:org.springframeworkが表示されます。 .util.Assert.state(ZLjava/util/function/Supplier;)V on KafkaMessagingMessageListenerAdapter。Spring-Kafka(1.2.0)で試したところ、そのエラーはなくなりました。このバージョンの非互換性が発生しましたか?
ここに私の設定クラスがあります
@EnableKafka
@Configuration
public class ImporterConfigs{
static Logger logger = Logger.getLogger(ImporterConfigs.class);
@Value("${kafka.bootstrap-servers}")
private static String bootstrapServers;
@Bean
public Map<String, Object> consumerKafkaConfigs() {
Map<String, Object> props = new HashMap<>();
// list of Host:port pairs used for establishing the initial connections to the Kakfa cluster
props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
// allows a pool of processes to divide the work of consuming and processing records
props.put(ConsumerConfig.GROUP_ID_CONFIG, "test-consumer-group");
return props;
}
@Bean
public ConsumerFactory<String, String> consumerFactory() {
return new DefaultKafkaConsumerFactory<>(consumerKafkaConfigs());
}
@Bean
public ConcurrentKafkaListenerContainerFactory<String, String> kafkaListenerContainerFactory() {
ConcurrentKafkaListenerContainerFactory<String, String> factory =
new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(consumerFactory());
return factory;
}
}
完全なスタックトレースは次のとおりです。

スプリングカフカ2.1
はSpring Frameworkに基づいています5.0
そしてそれはまさにあなたがそのエラーで見るものです:
Java.lang.NoSuchMethodError: org.springframework.util.Assert.state(ZLjava/util/function/Supplier;)
Spring Framework 4.3
(Spring Bootの基盤1.5
)は、Java 8をまだサポートしていません。
Spring Bootに切り替えることを検討する必要があります2.0
またはSpring Kafka 1.3.2
ブートと互換性があります1.5
バックグラウンドであり、Apache Kafka 1.0
