Failed to start bean ‘org.springframework.kafka.config.internalkafkalistenerendpointregistry’

    
      

        'Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'' error typically occurs when there is an issue with the configuration of the Spring Kafka listener. This error indicates that the bean responsible for managing the Kafka listeners failed to start.
      
      
There are several possible reasons for this error:
      

        

          Missing or incorrect Kafka configuration: Ensure that you have provided the correct configuration for the Kafka broker(s) in your application properties or YAML file. For example:
          
            
              spring.kafka.bootstrap-servers=localhost:9092
              spring.kafka.consumer.group-id=my-group-id
              spring.kafka.consumer.auto-offset-reset=earliest
            
          


          Missing or incorrect listener configuration: Check the configuration of your Kafka listener bean. Make sure that you have properly annotated your listener method with the `@KafkaListener` annotation and provided the necessary properties. For example:

            
              @KafkaListener(topics = "my-topic")
              public void processMessage(String message) {
                  // Process the Kafka message
              }
            
          


          Missing or incorrect dependencies: Ensure that you have the necessary dependencies in your project to use Spring Kafka. Check your build configuration (e.g., Maven or Gradle) and make sure that you have included the required dependencies, such as `spring-kafka`, `spring-core`, and `spring-context`.
        

If none of the above reasons resolve the issue, it may be necessary to provide more details about your specific application setup and error message for further analysis and troubleshooting.
