rabbitMQ_integeration_spring(七)

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);
    }
}
