Spring Boot Kafka: убедитесь, что сервер kafka запущен или нет

/ 11 июня 2018

Я пишу крайний случай, чтобы узнать, работает ли сервер kafka или нет, поэтому я написал планировщик 

@Service
@AllArgsConstructor
public class KafkaConnectionVerificationScheduler {

    private KafkaMessageDrivenChannelAdapter kafkaMessageDrivenChannelAdapter;

    @Scheduled(fixedDelayString = "${check.kafka.connectivity}")
    public void verifyIfKafkaServerIsRunning() throws IOException {
        if (!kafkaMessageDrivenChannelAdapter.isRunning()) {
            //Kafka server is not running, so flag it and stop all request to start new connection
        }
    }
}

Но когда я запускаю сервер, я получаю сообщение об ошибке: 

Description:

Parameter 0 of constructor in com.betstars.betsyncadapter.app.service.scheduler.KafkaConnectionVerificationScheduler required a bean of type 'org.springframework.integration.kafka.inbound.KafkaMessageDrivenChannelAdapter' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.integration.kafka.inbound.KafkaMessageDrivenChannelAdapter' in your configuration.

Мой pom.xml: 

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-kafka</artifactId>
    <version>2.3.0.RELEASE</version>
</dependency>

Сервер успешно запущен после замены KafkaMessageDrivenChannelAdapter на KafkaListenerEndpointRegistry, но kafkaListenerEndpointRegistry.isR.всегда ложное, даже если сервер работает, и мы можем отправить сообщение.
