我尝试了ksqldb并制作了一个docker-compose.yml像这样：

  # coppclark- static resources
  coppclark-static-http:
    image: springcloudstream/coppclarkstatic:0.0.1-SNAPSHOT
    container_name: coppclark-static-http
    ports:
      - '8080:8080'
    expose:
      - '8080'

然后从ksqldb内部创建了一个新的（自定义）连接器

CREATE SOURCE CONNECTOR holidayEvent WITH (
 'connector.class' = 'CoppclarkSourceConnector',
 'topic' = 'holidayEvent',
 'url' = 'http://coppclark-static-http:8080/coppclark.csv',
 'csv.parser' = true
);

这会导致这样的记录（在holidayEvent主题中）：

{
  "CENTER_ID": "150",
  "ISO_CURRENCY_CODE": "SRD",
  "ISO_COUNTRY_CODE": "SR",
  "RELATED_FINANCIAL_CENTER": "Paramaribo",
  "EVENT_YEAR": "2067",
  "EVENT_DATE": "20671225",
  "EVENT_DAY_OF_WEEK": "Sun",
  "EVENT_nAME": "Christmas Day",
  "FILE_TYPE": "C"
}

流已制作

CREATE STREAM holidayEventStream WITH(kafka_topic='holidayEvent', value_format='AVRO');

到目前为止，一切都很好，但是当我想从创建的流中进行选择时，出现了以下错误：

ksql> select * from  HOLIDAYEVENTSTREAM EMIT CHANGES;
Failed to construct kafka consumer
Caused by: Class
        io.confluent.monitoring.clients.interceptor.MonitoringConsumerInterceptor cannot
        be found
Caused by:
        io.confluent.monitoring.clients.interceptor.MonitoringConsumerInterceptor

我确定我错过了一些东西，但不知道下一步该怎么做。

问候 雷恩

答案 0 :(得分：1)

从您的ksqldb-server服务中删除这两行：

KSQL_PRODUCER_INTERCEPTOR_CLASSES: "io.confluent.monitoring.clients.interceptor.MonitoringProducerInterceptor"
KSQL_CONSUMER_INTERCEPTOR_CLASSES: "io.confluent.monitoring.clients.interceptor.MonitoringConsumerInterceptor"

ksqlDB 0.6不附带拦截器。
