springboot项目配置多个kafka的示例代码

作者:CccccDi

这篇文章主要介绍了springboot项目配置多个kafka,本文通过示例代码给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

1.spring-kafka

<dependency>
   <groupId>org.springframework.kafka</groupId>
   <artifactId>spring-kafka</artifactId>
   <version>1.3.5.RELEASE</version>
</dependency>

2.配置文件相关信息

kafka.bootstrap-servers=localhost:9092
kafka.consumer.group.id=20230321
#可以并发消费的线程数 (通常与partition数量一致)
kafka.consumer.concurrency=10
kafka.consumer.enable.auto.commit=false
        
kafka.bootstrap-servers.pic=localhost:29092
kafka.consumer.group.id.pic=20230322_pic
kafka.consumer.concurrency.pic=10
kafka.consumer.enable.auto.commit.pic=false

3.kafka配置类

@Configuration
@EnableKafka
public class KafkaConsumerConfig {

    @Value("${kafka.consumer.group.id}")
    private String groupId;

    @Value("${kafka.consumer.concurrency}")
    private int concurrency;

    @Value("${kafka.consumer.enable.auto.commit}")
    private String autoCommit;

    @Value("${kafka.bootstrap-servers}")
    private String bootstrapServer;


    @Value("${kafka.consumer.group.id.pic}")
    private String groupIdPic;

    @Value("${kafka.consumer.concurrency.pic}")
    private int concurrencyPic;

    @Value("${kafka.consumer.enable.auto.commit.pic}")
    private String autoCommitPic;

    @Value("${kafka.bootstrap-servers.pic}")
    private String bootstrapServerPic;


    @Bean
    public ConsumerFactory<String, String> consumerFactory() {
        String bootstrapServers = bootstrapServer;
        Map<String, Object> configProps = new HashMap<>(16);
        configProps.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
        configProps.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        configProps.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        configProps.put(ConsumerConfig.GROUP_ID_CONFIG, groupId);
        configProps.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, autoCommit);
        return new DefaultKafkaConsumerFactory<>(configProps);
    }

 
    @Bean
    public ConcurrentKafkaListenerContainerFactory<String, String> kafkaListenerContainerFactory() {
        ConcurrentKafkaListenerContainerFactory<String, String> factory =
                new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(consumerFactory());
        factory.setConcurrency(concurrency);
        factory.getContainerProperties().setAckMode(AbstractMessageListenerContainer.AckMode.MANUAL_IMMEDIATE);
        return factory;
    }




    @Bean
    public ConsumerFactory<String, String> consumerFactoryPic() {
        String bootstrapServers = bootstrapServerPic;
        Map<String, Object> configProps = new HashMap<>(16);
        configProps.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, bootstrapServers);
        configProps.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        configProps.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        configProps.put(ConsumerConfig.GROUP_ID_CONFIG, groupIdPic);
        configProps.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, autoCommitPic);
        return new DefaultKafkaConsumerFactory<>(configProps);
    }


    @Bean
    public ConcurrentKafkaListenerContainerFactory<String, String> kafkaListenerContainerFactoryPic() {
        ConcurrentKafkaListenerContainerFactory<String, String> factory =
                new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(consumerFactoryPic());
        factory.setConcurrency(concurrencyPic);
        factory.getContainerProperties().setAckMode(AbstractMessageListenerContainer.AckMode.MANUAL_IMMEDIATE);
        return factory;
    }
}

4.消费主题消息

@KafkaListener(topics = "xxxxx", containerFactory = "kafkaListenerContainerFactoryPic")
    public void receive(ConsumerRecord<String, String> message, Acknowledgment ack) {
        try {
            String jsonString = message.value();
            if (StringUtils.isNoneBlank(jsonString)) {
                log.info("消费:{}",jsonString);
                //TODO ....
            }
        } catch (Exception e) {
            log.error(" receive topic error ", e);
        } finally {
            ack.acknowledge();
        }
    }

@KafkaListener(topics = "xxxxxx", containerFactory = "kafkaListenerContainerFactory")
    public void receive(ConsumerRecord<String, String> message, Acknowledgment ack) {
        try {
            if (StringUtils.isNoneBlank(message.value())) {
                  //TODO ....
            }
        } catch (Exception e) {
            logger.error(" receive topic error ", e);
        } finally {
            ack.acknowledge();
        }
    }
