Spring Integration Kafka adaptor not producing message

问题


I am struggling this for days now.

I am using SI adaptor for kafka under Spring-boot container.

I have configured zookeeper and kafka on my machine. I also created console producer and consumer tested it and everything works fine(I manage to produce vis the console messages and have the console consumer to consume them).

I tried now to produce messages via Spring integration kafka outbound adapter but the console consumer wont consume the message

SI/Spring xd xml:

<int:publish-subscribe-channel id="inputToKafka"/>


    <int-kafka:outbound-channel-adapter id="kafkaOutboundChannelAdapter"
                                        kafka-producer-context-ref="kafkaProducerContext"
                                        auto-startup="true"
                                        order="1"
                                        channel="inputToKafka">

    </int-kafka:outbound-channel-adapter>


    <int-kafka:producer-context id="kafkaProducerContext">
        <int-kafka:producer-configurations>
            <int-kafka:producer-configuration broker-list="localhost:9092"
                                              async="true"
                                              topic="zerg.hydra"
                                              compression-codec="default"/>
        </int-kafka:producer-configurations>
    </int-kafka:producer-context>

    <task:executor id="taskExecutor" pool-size="5" keep-alive="120" queue-capacity="500"/>
</beans>

Java:

@Named
public class KafkaProducer {

    @Autowired
    @Qualifier("inputToKafka")
    MessageChannel inputToKafka;


    public void sendMessageToKafka(String message)
    {
        inputToKafka.send(
                MessageBuilder.withPayload(message)
                        .setHeader("messageKey", "3")
                        .setHeader("topic", "zerg.hydra").build());

    }

}

this is how I run kafka console consumer: 

bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic zerg.hydra --from-beginning

I tried in the same app to use the Offical Kafka client producer and it worked just fine:

@Named
public class KafkaProducerJava {

    ProducerConfig config=null;
    Producer<String, String> producer;
    Properties props=null;

    @PostConstruct
    public void init()
    {
        props = new Properties();

        props.put("metadata.broker.list", "localhost:9092");
        props.put("serializer.class", "kafka.serializer.StringEncoder");
       // props.put("partitioner.class", "example.producer.SimplePartitioner");
        props.put("request.required.acks", "1");



    }


    public void sendMsgToKafka(String msg)
    {
        config= new ProducerConfig(props);
        producer=new Producer<String, String>(config);
        KeyedMessage<String, String> data = new KeyedMessage<String, String>("test", "", msg);

        producer.send(data);
        producer.close();
    }

Any idea why the message never reached to my consumer via the Spring Integration kafka adaptor??

I just ran it in XD and it worked fine for me...

I also wrote this test case...

public class OutboundTests {

    @Test
    public void test() throws Exception {
        KafkaProducerContext<String, String> kafkaProducerContext = new KafkaProducerContext<String, String>();
        ProducerMetadata<String, String> producerMetadata = new ProducerMetadata<String, String>("test");
        producerMetadata.setValueClassType(String.class);
        producerMetadata.setKeyClassType(String.class);
        Encoder<String> encoder = new StringEncoder<String>();
        producerMetadata.setValueEncoder(encoder);
        producerMetadata.setKeyEncoder(encoder);
        ProducerFactoryBean<String, String> producer = new ProducerFactoryBean<String, String>(producerMetadata, "localhost:9092");
        ProducerConfiguration<String, String> config = new ProducerConfiguration<String, String>(producerMetadata, producer.getObject());
        kafkaProducerContext.setProducerConfigurations(Collections.singletonMap("test", config));
        KafkaProducerMessageHandler<String, String> handler = new KafkaProducerMessageHandler<String, String>(kafkaProducerContext);
        handler.handleMessage(MessageBuilder.withPayload("foo")
                .setHeader("messagekey", "3")
                .setHeader("topic", "test")
                .build());
    }

}

...to simulate what you are doing and that worked too. Are you seeing any logged exceptions? I see you are not setting the key/value types and encoders.

EDIT:

As discussed in the comments, the issue is that you are using an async producer. In your test example that "works", you are closing the producer, which flushes the queue. By default, the queue won't be flushed for 5 seconds and your test case is not waiting long enough.

I updated my test to include an XML configured version, and reduced the queue.buffering.max.ms to 500ms and added code to the test to wait a couple of seconds before terminating.

See the new commit for details.




回答2:


I was facing the same issue since morning and finally found the solution. If you prefix the topic with kafka as given below

.setHeader("kafka_topic", "zerg.hydra")

This is a issue with API as internally, while looking up the key from from the message header, kafka_ is getting prefixed.
