我正在尝试使用SpringBoot（1.5.9）和Spring-kafka（2.1.0）来设置Kafka Consumer。但是，当我启动我的应用程序时，我在Kafka MessagingMessageListenerAdapter上获得了java.lang.NoSuchMethodError：org.springframework.util.Assert.state（ZLjava / util / function / Supplier;）V。我尝试使用Spring-Kafka（1.2.0）并且错误消失了。有没有其他人遇到这个版本不兼容？
这是我的配置类
@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;
}
}
这是完整的堆栈跟踪：

Spring-kafka 2.1基于Spring Framework 5.0，这正是您所看到的错误：
java.lang.NoSuchMethodError: org.springframework.util.Assert.state(ZLjava/util/function/Supplier;)
Spring Framework 4.3（Spring Boot 1.5的基础）尚不支持Java 8。
您应该考虑切换到Spring Boot 2.0或坚持使用与Boot 1.3.2背景兼容的Spring Kafka 1.5，并且可以为Apache Kafka 1.0 Client重新配置。
