配置信息指定要连接的Kafka集群,然后创建消费者实例(KafkaConsumer),消费者会订阅主题,最后使用一个循环不断地轮询消费消息: final Properties consumerProperties = new Properties(); consumerProperties.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, kafka); consumerProperties.put(ConsumerConfig.GROUP_ID_CONFIG, "brok...
spring.kafka.consumer.group-id=group_id ``` - 通过配置"spring.kafka.consumer.group-id"属性,我们指定了消费者的组ID。 ### 步骤4:启动Spring Boot应用程序 ```java @SpringBootApplication public class KafkaConsumerApplication { public static void main(String[] args) { SpringApplication.run(KafkaCons...

在Springboot项目中,一般通过方法上的@KafkaListener注解来注册Consumer,在Springboot服务启动过程中,通过实现了Springboot的扩展点的KafkaListenerAnnotationBeanPostProcessor类,在postProcessAfterInitialization方法中识别含有@KafkaListener注解的方法,并注册至KafkaListenerEndpointRegistry中(详细的源码在此不展开描述,有兴...
