rabbitMQ_integeration

参考了其他博主的资料，整理成完整的代码，直接拷贝就可以测试。

一、创建一个properties文件

mq.host=127.0.0.1

mq.username=root

mq.password=root

mq.port=

mq.vhost=testmq

mq.vhost表示rabbitMQ虚拟主机，类似一台电脑里面划分了多个虚拟主机，每个虚拟主机都可以有交换器，队列，感觉又类似于一种命令空间。

创建的虚拟主机的可以使用rabbitMQ的工具rabbitmqctl

在命令行中键入rabbitmqctl add_vhost testmq即可创建这个虚拟主机，

创建root用户，rabbitmqctl add_user root root,

创建了虚拟主机之后还需要给root用户授权，授权命令

rabbitmqctl set_permissions -p testmq root .* .* .*

二、spring配置文件和pom.xml

    </dependencies>

    <build>

        <finalName>rabbitMQ_integerationSpring</finalName>

    </build>

</project>

三、监听器，实现MessageListener接口

package com.rabbitMQ.listener;

import org.springframework.amqp.core.Message;

import org.springframework.amqp.core.MessageListener;

public class QueueListenter implements MessageListener {

    @Override

    public void onMessage(Message msg) {

        try{

            System.out.println(msg.toString());

            System.out.println(new String(msg.getBody()));

        }catch(Exception e){

            e.printStackTrace();

        }

    }

}

四、定义一个接口

package com.rabbitMQ.service;

public interface MQProducer {

  /**

   * 发送消息到指定队列

   * @param queueKey

   * @param object

   */

  public void sendDataToQueue(String queueKey, Object object);

}

五、实现MQProducer接口

package com.rabbitMQ.service.impl;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.amqp.core.AmqpTemplate;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import com.rabbitMQ.service.MQProducer;

@Service

public class MQProducerImpl implements MQProducer {

    @Autowired

    private AmqpTemplate amqpTemplate;

    private final static Logger LOGGER = LoggerFactory.getLogger(MQProducerImpl.class);

    @Override

    public void sendDataToQueue(String queueKey, Object object) {

        try {

            //将Java对象转换为消息发送到匹配Key的交换机中Exchange，由于配置了JSON转换，这里是将Java对象转换成JSON字符串的形式。

            amqpTemplate.convertAndSend(queueKey, object);

        } catch (Exception e) {

            LOGGER.error(e.getMessage());

        }

    }

}

六、测试

package com.rabbitMQ.test;

import java.util.HashMap;

import java.util.Map;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.rabbitMQ.service.MQProducer;

@RunWith(value = SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {

    "classpath:application-mq.xml"})

public class TestQueue{

    @Autowired

    MQProducer mqProducer;

    final String queue_key = "test_queue_key";

    @Test

    public void send(){

        Map<String,Object> msg = new HashMap<String, Object>();

        msg.put("data","hello,rabbmitmq!");

        mqProducer.sendDataToQueue(queue_key,msg);

    }

}
