Kafka unable to send/receive the message

Question

I'm trying to send a message with Kafka but everytime I send I get this message in the console:

My docker compose is:

  version: '3'

services:
  zookeeper:
    image: wurstmeister/zookeeper
    container_name: zookeeper
    ports:
      - "2181:2181"


  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME:  localhost
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181

My docker producer configuration:

 @Value("${spring.kafka.bootstrap-servers}") //spring.kafka.bootstrap-servers: localhost:9092
    private String bootstrapServers;

    public Map<String, Object> producerConfig(){
        Map<String, Object> props = new HashMap<>();
        props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
        props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
        props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
        return props;
    }

    @Bean
    public ProducerFactory<String, String> producerFactory(){
       return new DefaultKafkaProducerFactory<>(producerConfig());
    }

    @Bean
    public KafkaTemplate<String, String> kafkaTemplate(
            ProducerFactory<String, String> producerFactory
    ){
        return new KafkaTemplate<>(producerFactory);
    }

@Bean
    public NewTopic myTopic(){
        return TopicBuilder.name("Robs")
                .build();
    }

My consumer configuration:

  @Value("${spring.kafka.bootstrap-servers}")
private String bootstrapServers;

public Map<String, Object> consumerConfig(){
    Map<String, Object> props = new HashMap<>();
    props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
    props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringSerializer.class);
    props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringSerializer.class);
    return props;
}

@Bean
public ConsumerFactory<String, String> consumerFactory(){
    return new DefaultKafkaConsumerFactory<>(consumerConfig());
}

@Bean
public KafkaListenerContainerFactory<
        ConcurrentMessageListenerContainer<String, String>> factory(
        ConsumerFactory<String, String> consumerFactory){
    ConcurrentKafkaListenerContainerFactory<String, String> factory = new ConcurrentKafkaListenerContainerFactory<>();
    factory.setConsumerFactory(consumerFactory);
    return factory;
}

My controller:

 private final  KafkaTemplate<String, String> kafkaTemplate;


    @PostMapping("/send")
    public ResponseEntity<String> sendMessage(@RequestParam String message){
        kafkaTemplate.send("Robs",message);
        return ResponseEntity.ok("Message sent to topic: Robs");

    }

 @KafkaListener(
            topics = "Robs",
            groupId = "groupId"
    )
    void listener(String data){
        System.out.println("Received: "+data);
    }

I get this in the console:

ERROR 10340 --- [ad | producer-1] o.s.k.support.LoggingProducerListener    : Exception thrown when sending a message with key='null' and payload='Ciao...... Hola' to topic Robs:

org.apache.kafka.common.errors.TimeoutException: Expiring 3 record(s) for Robs-0:120000 ms has passed since batch creation

Does anybody know what I m doing wrong? thanks!!

`KAFKA_ADVERTISED_HOST_NAME` is a deprecated property. Use `KAFKA_ADVERTISED_LISTENERS` — OneCricketeer, Nov 04 '22 at 16:54
@OneCricketeer should I give the value: "localhost" to this property? — Robs, Nov 07 '22 at 08:17
Depends where you need to connect from. If your Spring code is also running in a Docker container, then no. Please refer answer in linked duplicate post — OneCricketeer, Nov 07 '22 at 16:19
