【记录】【springboot】【kafka】【KafkaStreams】报错Use a different TimestampExtractor to process this data

问题：springboot集成kafka，并由KafkaStreams处理，启动报错

org.apache.kafka.streams.errors.StreamsException: Input record ConsumerRecord(topic = crawler_events, partition = 0, offset = 0, CreateTime = -1, serialized key size = -1, serialized value size = 187, headers = RecordHeaders(headers = [], isReadOnly = false), key = null, value = {XXX}) has invalid (negative) timestamp. Possibly because a pre-0.10 producer client was used to write this record to Kafka without embedding a timestamp, or because the input topic was created before upgrading the Kafka cluster to 0.10+. Use a different TimestampExtractor to process this data.

解决：去掉@EnableKafkaStreams，加入bean，和相关类

@Bean(
        name = {"defaultKafkaStreamsBuilder"}
)
public StreamsBuilderFactoryBean defaultKafkaStreamsBuilder(@Qualifier("defaultKafkaStreamsConfig") ObjectProvider<KafkaStreamsConfiguration> streamsConfigProvider, ObjectProvider<StreamsBuilderFactoryBeanCustomizer> customizerProvider) {
    KafkaStreamsConfiguration streamsConfig = (KafkaStreamsConfiguration)streamsConfigProvider.getIfAvailable();
    if (streamsConfig != null) {
        Properties properties = streamsConfig.asProperties();
        properties.put(StreamsConfig.DEFAULT_TIMESTAMP_EXTRACTOR_CLASS_CONFIG, MyEventTimeExtractor.class.getName());
        StreamsBuilderFactoryBean fb = new StreamsBuilderFactoryBean(streamsConfig);
        StreamsBuilderFactoryBeanCustomizer customizer = (StreamsBuilderFactoryBeanCustomizer)customizerProvider.getIfUnique();
        if (customizer != null) {
            customizer.configure(fb);
        }

        return fb;
    } else {
        throw new UnsatisfiedDependencyException(KafkaStreamsDefaultConfiguration.class.getName(), "defaultKafkaStreamsBuilder", "streamsConfig", "There is no 'defaultKafkaStreamsConfig' " + KafkaStreamsConfiguration.class.getName() + " bean in the application context.\nConsider declaring one or don't use @EnableKafkaStreams.");
    }
}
