org.apache.kafka.common.KafkaException: Failed to construct kafka consumer

I am manually starting Zookeeper, then Kafka server and finally the Kafka-Rest server with their respective properties file. Next, I am deploying my Spring Boot application on tomcat

In the Tomcat log trace, I am getting the Error org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is org.apache.kafka.common.KafkaException: Failed to construct kafka consumer and my application is failing to startup

My Receiver and Sender classes are not annotated with any annotations such as @Component or @Service. Does it make any difference?

@Configuration public class InventorySenderConfig @Configuration @EnableKafka public class InventoryReceiverConfig @Component public class KafkaConfig @Configuration public class ProducingChannelConfig @Configuration public class ConsumingChannelConfig @RestController public class KafkaWebhookController @Service("webhookService") public class KafkaServiceImpl @EnableIntegration @SpringBootApplication @ComponentScan("com.psl.kafka") public class SpringKafkaWebhookServiceApplication extends SpringBootServletInitializer 

These are my class annotations. Do they look to be OK or I need to change something ?

Do I need to define any Interceptor classes that I have added as config in ProducingChannelConfig, ConsumingChannelConfig as well as InventoryReceiverConfig classes ?

Caused by: java.lang.ClassNotFoundException: org.apache.kafka.common.ClusterResourceListener

You are missing the kafka-clients jar from your class path. What are you using for dependency management? Maven and gradle should put this jar on the class path for you automatically.

Your kafka version is older than it should, your problematic class ClusterResourceListener expect version to be higher than 0.10.1.0, and your version is lower 0.10.0.1.

Just upgrade your kafka jars and it'll fix this issue.

There will be one invocation of onUpdate(ClusterResource) after each metadata response. Note that the cluster id may be null when the Kafka broker version is below 0.10.1.0.

Check out if you're using StringDeserializer instead of StringSerializer

properties.setProperty(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName()); properties.setProperty(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName()); 

I also encountered this error in one of my recent project. The error could also be as a result of missing Kafka server. The app is trying to find configuration or server at application.properties file (PS: your app loads from application.properties if you don't specify which profile the app should load from).

Solution Edit your configuration(if using IntelliJ) and in the program argument, add the profile where you have added your Kafka bootstrap servers. This way, when the app starts, you have specified that the app runs on the specified profile which contains the Kafka bootstrap servers and details.

--spring.profiles.active= <profile_name> 

Alternatively, if you don't want to go through this long route, just create an application.properties file without specifying any profile and add all your Kafka settings in this properties file. It should work fine since, by default, the app runs application.properties.

In my case, i had used KafkaAvroSerialiser as deserializer in my consumer instead of KafkaAvroDeserializer

My problem was that the consumer expected message type as Activity (my own class) – KafkaItemReader<Activity, Finance> etc., and my producers and factories produced String (ProducerFactory<String, String> etc.).

To solve it, I changed producer to ProducerFactory<String, String> etc., and of course

String message = "checked in %s in %s starting at %s" .formatted(activity.getName(), activity.getLocation(), activity.getStartDate()); kafkaTemplate.send(checkInTopicName, message); 

to

kafkaTemplate.send(checkInTopicName, activity);
