結合Spring，運行RabbitMQ

RabbitMQ是用erlang實現的消息隊列系統，遵循AMQP（高級消息隊列協議）協議。性能還有可擴展性優於其他相似的框架，當然，新星kafka也不錯，大家可以上網查一下各種MQ框架的優缺點。

參考一下其他文章：http://blog.csdn.net/linsongbin1/article/details/47781187

RabbitMQ主要有三種交換器：direct、fanout、topic

direct就是一對一傳輸

fanout就是匹配傳輸

topic就是主題分發傳輸

還是看代碼吧

maven構建：pom.xml

實現direct交換器的傳輸：

生產端：MessageProducer

package com.xin.producer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;

/**
 * Created by lhx on 2016/9/5 9:56
 *
 * @Description
 */
@Service
public class MessageProducer {

    private Logger logger = LoggerFactory.getLogger(MessageProducer.class);

    @Resource
    private AmqpTemplate amqpTemplate;

    public void sendMessage(Object message){
        logger.info("to send message:{}",message);
        amqpTemplate.convertAndSend("queueTestKey",message);
    }
}

消費端：MessageConsumer

package com.xin.consumer;

import com.xin.producer.MessageProducer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessageListener;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by lhx on 2016/9/5 9:57
 *
 * @Description 消費接收
 */
public class MessageConsumer implements MessageListener {

    private Logger logger = LoggerFactory.getLogger(MessageConsumer.class);

    @Override
    public void onMessage(Message message) {
        logger.info("receive message:{}",message);
        System.out.println(new String(message.getBody()));
    }

    public static void main(final String... args) throws Exception {
        AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("application.xml");
        MessageProducer messageProducer = (MessageProducer) ctx.getBean("messageProducer");
        messageProducer.sendMessage("-------------hello,xin3453465465467456456456^^^^^^66666!");
        Thread.sleep(1000);
        ctx.destroy();
    }

}

運行main函數，服務端推消息到客戶端，客戶端就會收到message，打印出來。

2016-09-06 10:29:27,659 [main] INFO  [com.xin.producer.TopicProducer] - to send message:++++++++++++++++++hello,xin3453465465467456456456^^^^^^66666!hello,xin
