Question

我正面临https://github.com/confluentinc/kafka-streams-examples/issues/22中提到的类似问题。我根据注释中的建议更改了JDBC源配置，但仍然面临相同的问题。你能帮我我所缺少的吗？请在下面找到我的配置和我的Kafka Stream

JDBC源配置

connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
timestamp.column.name=changeDateTime
incrementing.column.name=id
connection.password=xxxx
tasks.max=2
table.types=TABLE

topic.prefix=Order-Topic
poll.interval.ms=5000
validate.non.null=true
query=select id, type, status, reservationId, processType, changeDateTime from order
key.converter.schemas.enable=false
value.converter.schemas.enable=true
value.converter=io.confluent.connect.avro.AvroConverter
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter.schema.registry.url=http://localhost:8081

       Properties property = new Properties();
        property.put(StreamsConfig.APPLICATION_ID_CONFIG, "Order_App_ID");

       StreamsConfig streamconfig = new StreamsConfig(property);

       Serde<String> stringSerde = Serdes.String();

       valueSpecificAvroSerde.configure(serdeConfig, false); // `false` for record values


        StreamsBuilder streamBuilder = new StreamsBuilder();
        KStream<String, T> kafkaEventStream = streamBuilder
                .stream(SRC_TOPIC, Consumed.with(stringSerde, valueSpecificAvroSerde))
                .peek((k, v) -> {
                    Order order = (Order) v;
                    LOG.info(
                        "============> ***************************************** Reservation Record {}, {}", k,
                        order.getReservationId(), order.getStatus(),
                        order.getChangeDateTime()); });

        LOG.info("Started Service {} with the following config:" + "\nInput topic    : {}" + "\nStream configs : {}",
                "KafkaStreamAppTest", SRC_TOPIC, printConfigs(property));
        KafkaStreams kafkaStream = new KafkaStreams(streamBuilder.build(), streamconfig);
        kafkaStream.start();
        kafkaStream.setUncaughtExceptionHandler((t, e) -> {
            LOG.error("Thread {} had a fatal error {}", t, e, e);
        });
        try {
            Thread.sleep(35000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        LOG.info("Shutting down the Yelling APP now");
        kafkaStream.close();

找不到类io.confluent.connect.avro.ConnectDefault
