2.配置kafka(配置傳送者，以及消費者，通過MyMessageListen)

package com.example.demo.n1;

import org.apache.kafka.clients.consumer.ConsumerConfig;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.common.serialization.StringDeserializer;
import org.apache.kafka.common.serialization.StringSerializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.kafka.annotation.EnableKafka;
import org.springframework.kafka.config.ConcurrentKafkaListenerContainerFactory;
import org.springframework.kafka.core.*;
import org.springframework.kafka.listener.KafkaMessageListenerContainer;
import org.springframework.kafka.listener.config.ContainerProperties;

import java.util.HashMap;
import java.util.Map;
import java.util.regex.Pattern;

@Configuration
@EnableKafka
public class KafkaConfig {

    /* --------------producer configuration-----------------**/
    @Bean
    public Map<String, Object> producerConfigs() {
        Map<String, Object> props = new HashMap<>();
        props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "xxx:9092");
        props.put(ProducerConfig.RETRIES_CONFIG, 0);
        props.put(ProducerConfig.BATCH_SIZE_CONFIG, 16384);
        props.put(ProducerConfig.LINGER_MS_CONFIG, 1);
        props.put(ProducerConfig.BUFFER_MEMORY_CONFIG, 33554432);
        props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
        props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
        return props;
    }

    @Bean
    public ProducerFactory<String, String> producerFactory() {
        return new DefaultKafkaProducerFactory<>(producerConfigs());
    }

    /* --------------consumer configuration-----------------**/
    @Bean
    public Map<String, Object> consumerConfigs() {
        Map<String, Object> props = new HashMap<>();
        props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, "xxx:9092");
        props.put(ConsumerConfig.GROUP_ID_CONFIG, "0");
        props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, true);
        props.put(ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG, 100);
        props.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "15000");
        props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class);
        return props;
    }

    @Bean
    ConcurrentKafkaListenerContainerFactory<String, String>
    kafkaListenerContainerFactory() {
        ConcurrentKafkaListenerContainerFactory<String, String> factory =
                new ConcurrentKafkaListenerContainerFactory<>();
        factory.setConsumerFactory(consumerFactory());
        return factory;
    }

    @Bean
    public ConsumerFactory<String, String> consumerFactory() {
        return new DefaultKafkaConsumerFactory<>(consumerConfigs());
    }


    //實際執行訊息消費的類，用於處理訊息，做一些業務邏輯
    @Bean
    public MyMessageListener myMessageListener(){
        return new MyMessageListener();
    }

    //消費者容器配置資訊
    @Bean
    public ContainerProperties containerProperties(){
        Pattern topicPattern = Pattern.compile("topic的名稱"); //匹配滿足正則的topic
        ContainerProperties containerProperties = new ContainerProperties(topicPattern);//訂閱滿足正則表示式的topic
        containerProperties.setMessageListener(myMessageListener());//訂閱的topic的訊息用myMessageListener去處理
        return containerProperties;
    }

    @Bean
    public KafkaMessageListenerContainer<String, String> kafkaMessageListenerContainer(){
        return new KafkaMessageListenerContainer<>(consumerFactory(),containerProperties());
    }


    /* --------------kafka template configuration-----------------**/
    @Bean
    public KafkaTemplate<String,String> kafkaTemplate() {
        KafkaTemplate<String, String> kafkaTemplate = new KafkaTemplate<>(producerFactory());
        kafkaTemplate.setDefaultTopic("defaultTopic");
        return kafkaTemplate;
    }

}
 

3.配置消費者，裡面可以寫業務邏輯

package com.example.demo.n1;

import org.apache.kafka.clients.consumer.ConsumerRecord;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.kafka.listener.MessageListener;


//監聽器必須實現MessageListener這個介面中onMessage方法
public class MyMessageListener implements MessageListener<String, String> {
    public final static Logger logger = LoggerFactory.getLogger(MyMessageListener.class);

    @Override//此方法處理訊息
    public void onMessage(ConsumerRecord<String, String> data) {
        String topic = data.topic();//消費的topic
        logger.info("-------------recieve message from {} topic-------------", topic);
        logger.info("partition:{}", String.valueOf(data.partition()));//消費的topic的分割槽
        logger.info("offset:{}", String.valueOf(data.offset()));//消費者的位置
        logger.info("get message from {} topic : {}", topic, data.value());//接收到的訊息
    }
}
 

4.測試控制器

package com.example.demo.n1;


import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.kafka.support.SendResult;
import org.springframework.util.concurrent.ListenableFuture;
import org.springframework.web.bind.annotation.*;

@RestController
public class TestController {
    public final static Logger logger = LoggerFactory.getLogger(TestController.class);
    @Autowired
    private KafkaTemplate<String,String> kafkaTemplate;//kafkaTemplate相當於生產者

    @RequestMapping(value = "/{topic}/send",method = RequestMethod.GET)
    public void sendMeessage(
            @RequestParam(value = "message",defaultValue = "hello world") String message,
            @PathVariable final String topic) {
        logger.info("start send message to {}",topic);
        ListenableFuture<SendResult<String, String>> listenableFuture = kafkaTemplate.send(topic,message);//傳送訊息，topic不存在將自動建立新的topic
        listenableFuture.addCallback(//新增成功傳送訊息的回撥和失敗的回撥
                result -> logger.info("send message to {} success",topic),
                ex -> logger.info("send message to {} failure,error message:{}",topic,ex.getMessage()));
    }

    @RequestMapping(value = "/default/send",method = RequestMethod.GET)
    public void sendMeessagedefault() {//傳送訊息到預設的topic
        logger.info("start send message to default topic");
        kafkaTemplate.sendDefault("你好，世界");
    }
}

可以看到kafka訊息傳送是通過kafkaTemplate.send()
