卡夫卡多话题消费

Question

   consumer.subscribe(Pattern.compile(".*"),new ConsumerRebalanceListener() {
            @Override
            public void onPartitionsRevoked(Collection<TopicPartition> clctn) {

            }

            @Override
            public void onPartitionsAssigned(Collection<TopicPartition> clctn) {
            }            
        });

如何在apache / kafka中使用正则表达式来使用所有主题？ 我尝试了上面的代码，但它没有用。

Answer 1

对于正则表达式，请使用以下签名

@Query(value = "select  "
        + "    DFBOGARM, 1 as DFSALVAR, 1 as DSTMND, 1 as DSTMNDAKK, 1 as KVANTUMAKK, "
        + "    sum(KVANTUM1) as KVANTUM1, "
        + "    (sum(DSTOMK) * 1000 / sum(KVANTUM1)) as DSTOMK, "
        + " (sum(DSTAKK) * 1000 / sum(KVANTUMAKK)) as DSTAKK "
        + "from NHODATA.ERHDSTV1 "
        + "where DFSALVAR in(52, 55) "
        + "group by DFBOGARM "
        + "order by DFBOGARM", nativeQuery = true)

E.g。以下代码段使消费者能够收听前缀为KafkaConsumer.subscribe(Pattern pattern, ConsumerRebalanceListener listener)

的所有主题
