spring boot + kafka 使用详细步骤

一,Kafka的安装以及配置

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

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

vi %kafka_home%/server.properties

############################# Server Basics #############################
broker.id=0
port=9092
host.name=阿里云内网ip
advertised.host.name=阿里云外网ip
delete.topic.enable=true

....其他的配置不变

二,Spring boot操作Kafka

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

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

#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.StringDeserializer
spring.kafka.consumer.value-deserializer=org.apache.kafka.common.serialization.StringDeserializer
spring.kafka.producer.key-serializer=org.apache.kafka.common.serialization.StringSerializer
spring.kafka.producer.value-serializer=org.apache.kafka.common.serialization.StringSerializer
spring.kafka.producer.batch-size=65536
spring.kafka.producer.buffer-memory=524288

@Component
public 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")));
}
}

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);
}
}

@SpringBootApplication
@EnableScheduling
public 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();
}
}

三,以上就是完整的spring boot整合Kafka消息队列的步骤.
