springboot整合kafka-笔记

配置pom.xml

这里我的springboot版本是2.3.8.RELEASE，使用的kafka-mq的版本是2.12

<dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>2.3.8.RELEASE</version><type>pom</type><scope>import</scope></dependency><dependency><groupId>org.springframework.kafka</groupId><artifactId>spring-kafka</artifactId><version>2.3.6.RELEASE</version></dependency><dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId><version>2.3.1</version></dependency></dependencies></dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.kafka</groupId><artifactId>spring-kafka</artifactId><version>2.3.6.RELEASE</version></dependency><dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId><version>2.3.1</version></dependency></dependencies>

配置application.yml

spring:kafka:bootstrap-servers: 10.1.5.212:9092

配置EnableKafka注解

@EnableKafka
@EnableScheduling
@SpringBootApplication
public class DemoApplication {public static void main(String[] args) {SpringApplication.run(DemoApplication.class,args);}
}

定义kafka消息生产者

package cn.test.kafka;import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.stereotype.Service;
@Slf4j
@Service
public class KafkaProducerService {@Autowiredprivate  KafkaTemplate<String, String> kafkaTemplate;private  String topic= "my816topic";public void sendMessage(String message){log.info("向kafka发送消息:{}",message);kafkaTemplate.send(topic,message);}
}

定义kafka消息消费者

package cn.test.kafka;import lombok.extern.slf4j.Slf4j;
import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.stereotype.Service;@Slf4j
@Service
public class KafkaConsumerService {@KafkaListener(topics = "my816topic",groupId = "mygroup")public void listen(String message){log.info("rec msg:{}",message);}
}

测试发送kafka消息

@Component
@Slf4j
public class TestJob {@Autowiredprivate ObjectMapper objectMapper;@Autowiredprivate KafkaProducerService kafkaProducerService;@Scheduled(cron = "0/13 * * * * ?")public void hwreg() {String s = null;try {s = objectMapper.writeValueAsString(new CityInfo("hefei"+System.currentTimeMillis(), 117.17, 31.52));} catch (JsonProcessingException e) {e.printStackTrace();}//测试发送字符串消息kafkaProducerService.sendMessage(s);}
