org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry

I am developing Spring Boot + Apache Kafka + Apache Zookeeper example. I've installed/setup Apache Zookeeper and Apache Kafka on my local Windows machine. I've taken a reference from link: https://www.tutorialspoint.com/spring_boot/spring_boot_apache_kafka.htm and executed code as is:

Setup: https://medium.com/@shaaslam/installing-apache-kafka-on-windows-495f6f2fd3c8

Error:

SpringKafkaTutorialspointApplication.java

@SpringBootApplication
public class SpringKafkaTutorialspointApplication implements CommandLineRunner{

    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;
    
    public void sendMessage(String message) {
        kafkaTemplate.send("tutorialspoint", message);
    }
    
    public static void main(String[] args) {
        SpringApplication.run(SpringKafkaTutorialspointApplication.class, args);
    }

    @Override
    public void run(String... args) throws Exception {
        sendMessage("Hi Welcome to Spring For Apache Kafka @@@@@@@@@");
    }
    
    @KafkaListener(topics = "tutorialspoint", groupId = "group-id")
    public void listen(String message) {
        System.out.println("Received Messasge in group - group-id: " + message);
    }
}

What can I try next to resolve this?

Solution

  • After spending many hours I found that I should be using below in KafkaConsumerConfig too.

    With the below changes code works fine.

    props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
