Question

以下字段导致我的Kafka Stream应用程序尝试生成消息时失败。

{
    "name" : "TS",
    "type" : {
      "type" : "long",
      "logicalType" : "timestamp-millis"
    },
    "doc" : "date time indicating the timestamp of the position (in UTC)"
  }

以下是Stream尝试将消息写入输出主题时的堆栈跟踪

用于生成消息的Serdes实例为

final Map<String, String> serdeConfig = Collections.singletonMap(AbstractKafkaAvroSerDeConfig.SCHEMA_REGISTRY_URL_CONFIG,"http://localhost:8081/");

final Serde<GenericRecord> valueGenericAvroSerde = new GenericAvroSerde();
        valueGenericAvroSerde.configure(serdeConfig, false); // `false` for record values

引起原因：org.apache.avro.AvroRuntimeException：未知数据类型org.joda.time.DateTime：
