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...
spring boot kafkaTemplate 生产者 多线程 springboot kafka stream,1、实时流式计算1.1概念一般流式计算会与批量计算相比较。在流式计算模型中,输入是持续的,可以认为在时间上是无界的,也就意味着,永远拿不到全量数据去做计算。同时,计算结果是持续输出的,也即计算
1.今天我们来看下springboot怎么整合kafka使用,首先我们要引入需要的jar包: <dependency><groupId>org.springframework.kafka</groupId><artifactId>spring-kafka</artifactId></dependency> 2.添加基本配置: ###【Kafka集群】###spring.kafka.bootstrap-servers=127.0.0.1:9092###【初始化生产者配置】### 重试...
