本文介绍如何使用Spring Boot 2与Kafka进行集成，包括通过Docker部署Kafka集群，配置Spring Boot项目引入Kafka依赖，并实现消息发送与监听的功能。

spring boot 2 跟kafka的配置

采用docker 安装kafka

docker run --name zookeeper -p 2181:2181 -t wurstmeister/zookeeper

docker run --name kafka -e KAFKA_ADVERTISED_HOST_NAME=localhost -e HOST_IP=localhost -e KAFKA_ADVERTISED_PORT=9092 -e KAFKA_ZOOKEEPER_CONNECT=zk:2181 -e KAFKA_BROKER_ID=1 -e ZK=zk -p 9092:9092 --link zookeeper:zk -t wurstmeister/kafka

其中pom依赖包为：

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

其次parent依赖于

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
</parent>

如果采用io来管理那么需要依赖

其中必须应用到最新版本的管理。

<platform-bom.version>Cairo-SR1</platform-bom.version

<dependency>
    <groupId>io.spring.platform</groupId>
    <artifactId>platform-bom</artifactId>
    <version>${platform-bom.version}</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

其中代码

package com.wj.product.common;

        import org.apache.kafka.clients.consumer.ConsumerRecord;
        import org.slf4j.Logger;
        import org.slf4j.LoggerFactory;
        import org.springframework.beans.factory.annotation.Autowired;
        import org.springframework.boot.CommandLineRunner;
        import org.springframework.boot.SpringApplication;
        import org.springframework.boot.autoconfigure.SpringBootApplication;
        import org.springframework.kafka.annotation.KafkaListener;
        import org.springframework.kafka.core.KafkaTemplate;

        import java.util.concurrent.CountDownLatch;
        import java.util.concurrent.TimeUnit;



@SpringBootApplication
public class KafkaTest implements CommandLineRunner {


    public static Logger logger = LoggerFactory.getLogger(KafkaTest.class);
    public static void main(String[] args) {
        SpringApplication.run(KafkaTest.class, args).close();
    }


    @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;



    private final CountDownLatch latch = new CountDownLatch(3);


    @Override
    public void run(String... args) throws Exception {
        kafkaTemplate.send("myTopic", "foo1");
        kafkaTemplate.send("myTopic", "foo2");
        kafkaTemplate.send("myTopic", "foo3");
        latch.await(60, TimeUnit.SECONDS);
    }
    @KafkaListener(topics = "myTopic")
    public void listen(ConsumerRecord<?, ?> cr) throws Exception {
        logger.info(cr.toString());
        latch.countDown();
    }
}
