我正在遵循异常风暴拓扑。

我正在使用已弃用的storm-kafka库。如果是上述异常的原因，那么请让我知道如何使用 storm-kafka-client库创建kafka spout，并将自定义方案传递给它。

谢谢。

您是否可以尝试将org.apache.kafka:kafka-clients工件放入与kafka_2.11相同版本的依赖项中？

关于如何使用storm-kafka-client，请在https://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-kafka-client.html的Storm页面上找到文档，并在https://github.com/apache/storm/blob/master/examples/storm-kafka-client-examples/src/main/java/org/apache/storm/kafka/spout/KafkaSpoutTopologyMainNamedTopics.java上找到示例

具体来说，您想要的是RecordTranslator。

ByTopicRecordTranslator<String, String> trans = new ByTopicRecordTranslator<>(
            (r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
            new Fields("topic", "partition", "offset", "key", "value"), TOPIC_0_1_STREAM);
        trans.forTopic(TOPIC_2,
            (r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
            new Fields("topic", "partition", "offset", "key", "value"), TOPIC_2_STREAM);
        return KafkaSpoutConfig.builder(bootstrapServers, new String[]{TOPIC_0, TOPIC_1, TOPIC_2})
            .setProp(ConsumerConfig.GROUP_ID_CONFIG, "kafkaSpoutTestGroup")
            .setRetry(getRetryService())
            .setRecordTranslator(trans)
            .setOffsetCommitPeriodMs(10_000)
            .setFirstPollOffsetStrategy(EARLIEST)
            .setMaxUncommittedOffsets(250)
.build();

例如，此命令将输出列出字段中每个记录的主题，分区，偏移量，键和值，并将TOPIC_2中的元组发送到与其他订阅主题不同的流。如果您不需要针对不同主题的不同方案，则可以使用SimpleRecordTranslator。
