springboot 1.5.2 集成kafka 简单例子

添加依赖

compile("org.springframework.kafka:spring-kafka:1.1.2.RELEASE")

添加application.properties

#kafka
# 指定kafka 代理地址，可以多个
spring.kafka.bootstrap-servers=192.168.59.130:9092,192.168.59.131:9092,192.168.59.132:9092
# 指定默认消费者group id
spring.kafka.consumer.group-id=myGroup
# 指定默认topic id
spring.kafka.template.default-topic= my-replicated-topic
# 指定listener 容器中的线程数，用于提高并发量
spring.kafka.listener.concurrency= 3
# 每次批量发送消息的数量
spring.kafka.producer.batch-size= 1000

 

configuration 启用kafka

package cn.xiaojf.today.data.kafka.configuration;import org.springframework.context.annotation.Configuration;
import org.springframework.kafka.annotation.EnableKafka;/*** kafka 配置* @author xiaojf 2017/3/24 14:09*/
@Configuration
@EnableKafka
public class KafkaConfiguration {}

 

消息生产者

package cn.xiaojf.today.data.kafka.producer;import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.RecordMetadata;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.kafka.core.KafkaOperations;
import org.springframework.kafka.core.KafkaTemplate;
import org.springframework.kafka.support.ProducerListener;
import org.springframework.stereotype.Component;/*** 消息生产者* @author xiaojf 2017/3/24 14:36*/
@Component
public class MsgProducer {@Autowiredprivate KafkaTemplate<String,String> kafkaTemplate;public void send() {kafkaTemplate.send("my-replicated-topic","xiaojf");kafkaTemplate.send("my-replicated-topic","xiaojf");kafkaTemplate.metrics();kafkaTemplate.execute(new KafkaOperations.ProducerCallback<String, String, Object>() {@Overridepublic Object doInKafka(Producer<String, String> producer) {//这里可以编写kafka原生的api操作return null;}});//消息发送的监听器，用于回调返回信息kafkaTemplate.setProducerListener(new ProducerListener<String, String>() {@Overridepublic void onSuccess(String topic, Integer partition, String key, String value, RecordMetadata recordMetadata) {}@Overridepublic void onError(String topic, Integer partition, String key, String value, Exception exception) {}@Overridepublic boolean isInterestedInSuccess() {return false;}});}
}

 

消息消费者

package cn.xiaojf.today.data.kafka.consumer;import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.stereotype.Component;/*** 消息消费者* @author xiaojf 2017/3/24 14:36*/
@Component
public class MsgConsumer {@KafkaListener(topics = {"my-replicated-topic","my-replicated-topic2"})public void processMessage(String content) {System.out.println(content);}}
