我正在使用 Spring kafka 1.0.3 来消费 kafka 消息。kafka中有2个主题，每个主题有1个分区。在 java 代码中，有 2 个 @KafkaListener 来消费每个主题消息。ConcurrentKafkaListenerContainerFactory 的并发设置为 1。但消息有时会延迟 20+ 秒。

@Configuration
@EnableKafka
public class KafkaConfig {

@Value("${kafka.brokers}")
private String brokers;

@Bean
public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer<String, String>>
kafkaListenerContainerFactory() {
    ConcurrentKafkaListenerContainerFactory<String, String> factory =
            new ConcurrentKafkaListenerContainerFactory<>();
    factory.setConsumerFactory(consumerFactory());
    factory.setConcurrency(1);
  factory.getContainerProperties().setAckMode(AbstractMessageListenerContainer.AckMode.MANUAL);
    return factory;
}


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

@Bean
public Map<String, Object> consumerConfigs() {
    Map<String, Object> props = new HashMap<>();
    props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, brokers);
    props.put(ConsumerConfig.GROUP_ID_CONFIG, "server-group");
    props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
    props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
    props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, false);
    props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "15000");
    return props;
}

@KafkaListenr 代码如下：

@KafkaListener(id = "serverInChannel",topics =   CommonContants.KAFKA_TOPIC.SERVER_IN_CHANNEL)
public void consumeInMessage(@Payload String data,
                                 @Header(KafkaHeaders.RECEIVED_TOPIC) String topic,
                              @Header(KafkaHeaders.RECEIVED_PARTITION_ID) String partitionId,
                              Acknowledgment ack) {
    logger.info("[serverInMessage]data=" + data);
    ack.acknowledge();
}

@KafkaListener(id = "webOutChannel",topics = CommonContants.KAFKA_TOPIC.WEB_OUT_CHANNEL)
public void consumeOutMessage(@Payload String data,
                               @Header(KafkaHeaders.RECEIVED_PARTITION_ID) String partitionId,
                               Acknowledgment ack) {
    logger.info("[webOutMessage]data=" + data);
    ack.acknowledge();
}

kafka 消息由 spring kafka 发送，日志在这里：

日志中有一些partitions assigned:[]，我不知道为什么assigned是空的。而在 webOutMessage 消息被消费后2016-09-26 16:16:45,870，下一个动作是消费者在 15+ 秒后重新平衡2016-09-26 16:17:01,099，所以下一条消息是在 15+ 秒后延迟。

有人知道为什么吗？

添加调试日志，不是每次都有延迟，有时候还可以：</p>
