Question

参考Spring kafka doc，我正在尝试实现一个Spring Boot应用程序，该应用程序可以手动监听kafka主题并确认。

@SpringBootApplication
public class TestApplication {

  public static void main(String[] args) {
    SpringApplication.run(TestApplication.class, args);
  }

  @KafkaListener(topics = "sample_log", containerFactory = "kafkaManualAckListenerContainerFactory")
  public void listen(ConsumerRecord<?, ?> cr, Acknowledgment ack) throws Exception {
      process(cr);
      ack.acknowledge();
  }
}

但是当我运行应用程序时，它会显示：

***************************
APPLICATION FAILED TO START
***************************
Description:
A component required a bean named 'kafkaManualAckListenerContainerFactory' that could not be found.
Action:
Consider defining a bean named 'kafkaManualAckListenerContainerFactory' in your configuration.

就我而言，Spring Kafka可能已经定义了kafkaManualAckListenerContainerFactory bean，因为它是一个提供的功能。如何在不手动定义bean的情况下修复错误？

Answer 1

您不需要containerFactory = "kafkaManualAckListenerContainerFactory"配置。只需将其完全删除，并依赖于Kafka的Spring Boot自动配置：https://docs.spring.io/spring-boot/docs/2.0.1.RELEASE/reference/htmlsingle/#boot-features-kafka
