Exception thrown when sending a message with key='1' and payload='message' to topic helloworld.t

i have made sender class using kafkatemplate bean to send payload to topic
with some configuration in SenderConfiguration class .
Sender Class
@Component
public class Sender {
private static final Logger LOGGER = (Logger) LoggerFactory.getLogger(Sender.class);
@Autowired
private KafkaTemplate<String, String> kafkaTemplate;
public void send(String topic, String payload) {
LOGGER.info("sending payload='{}' to topic='{}'", payload, topic);
kafkaTemplate.send(topic, "1", payload);
}
}
, senderConfiguration class
@Configuration
public class SenderConfig {
@Value("${kafka.bootstrap-servers}")
private String bootstrapServers;
@Bean
public Map<String, Object> producerConfigs() {
Map<String, Object> props = new HashMap<>();
// list of host:port pairs used for establishing the initial connections to the Kakfa cluster
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() {

}
@Bean
public KafkaTemplate<String, String> kafkaTemplate() {
return new KafkaTemplate<>(producerFactory());
}
@Bean
public Sender sender() {
return new Sender();
}
}
the problem is in sending not in producing
here the application.yml file properties
kafka:
bootstrap-servers: localhost:9092
topic:
helloworld: helloworld.t
and simply controller containing
@RestController
public class Controller {
protected final static String HELLOWORLD_TOPIC = "helloworld.t";
@Autowired
private Sender sender;
@RequestMapping("/send")
public String SendMessage() {
sender.send(HELLOWORLD_TOPIC, "message");
return "success";
}
}

Use the method that includes a key
kafkaTemplate.send(topic, key, payload);
Its not clear what key value you want to use, but it should evenly distribute amongst the partition count of the topic. For example, a random number within the range of the partition count.
