一,Kafka的安装以及配置

1.下载文件

wget http://mirror.bit.edu.cn/apache/kafka/0.11.0.0/kafka_2.11-0.11.0.0.tgz

2.安装

tar xzvf kafka_2.11-0.11.0.0.tgz -C /usr/local/

3.配置(服务器在阿里云ECS上)

vi %kafka_home%/server.properties############################# Server Basics #############################broker.id=0port=9092host.name=阿里云内网ipadvertised.host.name=阿里云外网ipdelete.topic.enable=true....其他的配置不变

二,Spring boot操作Kafka

1.Spring boot pom依赖

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.5.6.RELEASE</version>    <relativePath/> <!-- lookup parent from repository --></parent>

2.kafka依赖

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

3.kafka配置

#kafka相关配置spring.kafka.bootstrap-servers=阿里云外网ip:9092#设置一个默认组spring.kafka.consumer.group-id=defaultGroup#key-value序列化反序列化spring.kafka.consumer.key-deserializer=org.apache.kafka.common.serialization.StringDeserializerspring.kafka.consumer.value-deserializer=org.apache.kafka.common.serialization.StringDeserializerspring.kafka.producer.key-serializer=org.apache.kafka.common.serialization.StringSerializerspring.kafka.producer.value-serializer=org.apache.kafka.common.serialization.StringSerializerspring.kafka.producer.batch-size=65536spring.kafka.producer.buffer-memory=524288

4.kafka发送代码

@Componentpublic class KafkaSender {    @Autowired    private KafkaTemplate kafkaTemplate;    /**     * 发送消息到kafka,主题为test     */    public void sendTest(){        kafkaTemplate.send("test","hello,kafka  "  + LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS")));    }}

5.Kafka消费代码

public class KafkaConsumer {    /**     * 监听test主题,有消息就读取     * @param message     */    @KafkaListener(topics = {"test"})    public void consumer(String message){        log.info("test topic message : {}", message);    }}

6,启动测试代码

@SpringBootApplication@EnableSchedulingpublic class ServerApplication {    @Autowired    private KafkaSender kafkaSender;    public static void main(String[] args) {        SpringApplication.run(ServerApplication.class, args);    }    //然后每隔1分钟执行一次    @Scheduled(fixedRate = 1000 * 60)    public void testKafka() throws Exception {        kafkaSender.sendTest();    }}
