springboot 1.5.2 集成kafka 簡單例子

添加依賴

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

添加application.properties

#kafka
# 指定kafka 代理地址，可以多個
spring.kafka.bootstrap-servers=192.168.59.130:9092,192.168.59.131:9092,192.168.59.132:9092
# 指定默認消費者group id
spring.kafka.consumer.group-id=myGroup
# 指定默認topic id
spring.kafka.template.default-topic= my-replicated-topic
# 指定listener 容器中的線程數，用於提高並發量
spring.kafka.listener.concurrency= 3
# 每次批量發送消息的數量
spring.kafka.producer.batch-size= 1000

 

configuration 啟用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 {


}

 

消息生產者

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;

/**

@Component
public class MsgProducer {
    @Autowired
    private 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>() {
            @Override
            public Object doInKafka(Producer<String, String> producer) {
                //這里可以編寫kafka原生的api操作
                return null;
            }
        });

        //消息發送的監聽器，用於回調返回信息
        kafkaTemplate.setProducerListener(new ProducerListener<String, String>() {
            @Override
            public void onSuccess(String topic, Integer partition, String key, String value, RecordMetadata recordMetadata) {

            }

            @Override
            public void onError(String topic, Integer partition, String key, String value, Exception exception) {

            }

            @Override
            public boolean isInterestedInSuccess() {
                return false;
            }
        });
    }
}

 

消息消費者

package cn.xiaojf.today.data.kafka.consumer;

import org.springframework.kafka.annotation.KafkaListener;
import org.springframework.stereotype.Component;

/**
 * 消息消費者
 * @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);
    }


}
