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

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 {

    @Autowired
    private  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 {
 @Autowired
    private ObjectMapper objectMapper;

    @Autowired
    private 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);

}

测试发送kafka消息-控制台日志
