次次皮2024-06-07 10:52

1、导入依赖

<dependency>
    <groupId>org.springframework.kafka</groupId>
    <artifactId>spring-kafka</artifactId>
    <version>2.5.10.RELEASE</version>
</dependency>

2、yml配置

spring: 
    kafka:
        bootstrap-servers: localhost:9092    # kafka连接接地址
        consumer:
              group-id: test-consumer-group    # 消费者所属消息组
              enable-auto-commit: true    #设置自动提交
              auto-commit-interval: 3000    #自动提交的间隔时间

3、测试

-生产者

@Component
class KafkaProduce{
    @Autowired
    private KafkaTemplate kafkaTemplate;

    public void sendMessage(String topic, String content){
        kafkaTemplate.send(topic, content);
    }
}

-消费者

@Component
class kafkaConsumer{
    @KafkaListener(topics = {"test"})
    public void handleMessage(ConsumerRecord record){
        System.out.println(record.value());
    }
}

-测试方法

    @Autowired
    private KafkaProduce kafkaProduce;
    @Test
    void TestKafka(){
        kafkaProduce.sendMessage("test", "nihao");
        kafkaProduce.sendMessage("test", "nihaoma");

        try {
            sleep(1000 * 20);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

也可以使用offset Explorer 2.3.2进行测试，使用方法见我的这篇博文：
