Kafka——使用spring进行集成

生产者发送消息代码：

首先注入：

 @Autowired
    private KafkaTemplate<String, String> kafkaTemplate;

之后进行发送：

 ListenableFuture<SendResult<String, String>> result = kafkaTemplate.send(topic, key, valueString);

消费端：

/**
 * kafka消费
 * Created by liuhuichao on 2017/5/12.
 */
public class KafkaConsumerServer implements MessageListener<String, String> {
    private Logger logger = Logger.getLogger(KafkaConsumerServer.class);

    @Override
    public void onMessage(ConsumerRecord<String, String> record) {
        logger.info("KafkaConsumerServer=============kafkaConsumer开始消费=============");
        String topic = record.topic();
        String key = record.key();
        String value = record.value();
        long offset = record.offset();
        int partition = record.partition();
        logger.info("KafkaConsumerServer-------------topic:"+topic);
        logger.info("KafkaConsumerServer-------------value:"+value);
        logger.info("KafkaConsumerServer-------------key:"+key);
        logger.info("KafkaConsumerServer-------------offset:"+offset);
        logger.info("KafkaConsumerServer-------------partition:"+partition);
        logger.info("~~~~~~~~~~~~~kafkaConsumer消费结束~~~~~~~~~~~~~");
        System.out.println("消费成功***************************************************************");
    }
}

除了集成kafka,熟悉spring的同志们，可能还用spring集成过redis,hbase这些东西，可以完全放心把连接什么的都交给spring,自己只关注该关注的东西。
