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...

在Springboot 环境下,最简单的consumer实现起来非常简单,简单到如下: spring: kafka: consumer: group-id: "" enable-auto-commit: true auto-commit-interval: 100 key-deserializer: org.apache.kafka.common.serialization.StringDeserializer value-deserializer: org.apache.kafka.common.serialization.StringDeserializer...

SpringBoot配置Kafka的生产者与消费者 1. 配置pom.xml 文件 <dependency> <groupId>org.springframework.kafka</groupId> <artifactId>spring-kafka</artifactId> </dependency> 2. 配置application.properties 文件 #zookeeper连接地址 kafka.consumer.zookeeper.connect=192.168.16.23:8082 ...
return new KafkaProperties(); } 2、配置消费者工厂,消费者工厂绑定对应的KafkaProperties @Bean public ConsumerFactory twoConsumerFactory(@Autowired @Qualifier("twoKafkaProperties") KafkaProperties twoKafkaProperties){ return new DefaultKafkaConsumerFactory(twoKafkaProperties.buildConsumerProperties()); ...
