在Kafka Spring Boot中重用AdminClient Bean

要使用端口9094上的管理客户端连接到Kafka，我有以下两个主要类，其中包括以下应用程序.yml：

@EnableKafka
@SpringBootApplication
@ConfigurationPropertiesScan
public class KafkaSpringApiApplication {
    public static void main(String[] args) {
        SpringApplication.run(KafkaSpringApiApplication.class, args);
    }
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

}
package org.kafka.config;

import org.apache.kafka.clients.admin.AdminClient;
import org.apache.kafka.clients.admin.AdminClientConfig;
import org.kafka.reader.Kafka;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.kafka.annotation.EnableKafka;
import org.springframework.kafka.core.KafkaAdmin;
import org.springframework.stereotype.Component;

import java.util.HashMap;
import java.util.Map;

@Component
public class AdminConfigurer {

    @Autowired
    private Kafka kafkaConfig;

    @Bean
    public Map<String, Object> kafkaAdminProperties() {
        final Map<String, Object> configs = new HashMap<>();
        configs.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, kafkaConfig.getBootstrapServers());
        if(kafkaConfig.getProperties().getSasl().getEnabled() && kafkaConfig.getSsl().getEnabled()) {
            configs.put("sasl.mechanism", kafkaConfig.getProperties().getSasl().getMechanism());
            configs.put("security.protocol", kafkaConfig.getProperties().getSasl().getSecurity().getProtocol());
            configs.put("ssl.keystore.location", kafkaConfig.getSsl().getKeystoreLocation());
            configs.put("ssl.keystore.password", kafkaConfig.getSsl().getKeystorePassword());
            configs.put("ssl.truststore.location", kafkaConfig.getSsl().getTruststoreLocation());
            configs.put("ssl.truststore.password", kafkaConfig.getSsl().getTruststorePassword());
            configs.put("sasl.jaas.config", String.format(kafkaConfig.getJaasTemplate(),
                    kafkaConfig.getProperties().getSasl().getJaas().getConfig().getUsername(),
                    kafkaConfig.getProperties().getSasl().getJaas().getConfig().getPassword()));
            configs.put("ssl.endpoint.identification.algorithm", "");
        }
        return configs;
    }

    @Bean
    public AdminClient getClient() {
        return AdminClient.create(kafkaAdminProperties());
    }

}

Application.yml

kafka:
  bootstrap-servers: localhost:9094
  properties:
    sasl:
      enabled: false
      jaas:
        config:
          username: XXX
          password: XXX
      mechanism: SCRAM-SHA-256
      security:
        protocol: SASL_SSL
  ssl:
    enabled: false
    truststore-location: /opt/app/secrets/kafka.consumer.truststore.jks
    truststore-password: XXX
    keystore-location: /opt/app/secrets/kafka.consumer.keystore.jks
    keystore-password: XXX
    key-password: XXX

服务等级

@Service
public class TopicService {

  private static final Logger LOG = LoggerFactory.getLogger(TopicService.class);
  @Autowired
  private AdminClient adminClient;

public void createTopic(Topic topic) throws ExecutionException, InterruptedException {
    adminClient
            .createTopics(Collections.singletonList(ServiceHelper.fromTopic(topic)))
            .values()
            .get(topic.getName())
            .get();
  }
}

我在日志中看到的问题是最初它使用管理客户端配置并正确连接到端口9094上的Kafka，但当我尝试创建主题时，它使用的是端口9092而不是

我不明白为什么它不再使用Bean来执行管理任务。

apache-kafka

在您的Kafka服务器属性上，确保已在正确的端口上定义了通告的监听程序

listeners=SASL_SSL://:9094
advertised.listeners=SASL_SSL://localhost:9094
