spring集成rabbitmq

maven配置
//pom.xml

      com.rabbitmq
      amqp-client
      3.5.1


      org.springframework.amqp
      spring-rabbit
      1.4.5.RELEASE

rabbitMQ配置文件
//rabbitmq-config.properties
mq.host=127.0.0.1
mq.username=test
mq.password=123456
mq.port=5672
mq.vhost=testmq
mq.queueName=test
Spring配置

    
    

    
    

    
    
申明一个消息队列Queue
//application-mq.xml

  • tips
    durable:是否持久化
    exclusive: 仅创建者可以使用的私有队列,断开后自动删除
    auto_delete: 当所有消费客户端连接断开后,是否自动删除队列
交换机定义

    
        
    

  • tips
    rabbit:direct-exchange:定义exchange模式为direct,意思就是消息与一个特定的路由键完全匹配,才会转发。
    rabbit:binding:设置消息queue匹配的key
生成者 RabbitMQService.interface
// 定义rabbitMQ接口
public interface RabbitMQService {
    /**
     * 发送消息到指定队列
     * @param queueKey
     * @param object
     */
    public void sendDataToQueue(String queueKey, Object object);
}
  • 实现接口
import com.haomo.delivery.service.RabbitMQService;
import org.jboss.logging.Logger;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by yide on 2018/9/7.
 */
@Service
public class RabbitMQImpl implements RabbitMQService {
    @Autowired
    private AmqpTemplate amqpTemplate;

    private final static Logger LOGGER = Logger.getLogger(RabbitMQImpl.class);
    /* (non-Javadoc)
     * @see com.stnts.tita.rm.api.mq.MQProducer#sendDataToQueue(java.lang.String, java.lang.Object)
     */
    @Override
    public void sendDataToQueue(String queueKey, Object object) {
        try {
            amqpTemplate.convertAndSend(queueKey, object);
        } catch (Exception e) {
            LOGGER.error(e);
        }

    }
}
  • tips:
    convertAndSend: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。原文:Convert a Java object to an Amqp Message and send it to a default exchange with a specific routing key.
controller接口调用
@Controller
public class OrderInterface {

    // 注入rabbitmq服务
    @Autowired
    RabbitMQService rabbitMQService;

    @RequestMapping(value = "/test/new",
            method = RequestMethod.POST,
            produces = "application/json;charset=UTF-8")
    @ResponseBody
    public Object createOvertime(
            HttpServletRequest request,
            @RequestHeader(value = "X-Auth-Token",required = false) String token,
            @RequestParam(value = "content") String content
    ) {
        Map map = new HashMap();
        map.put("content",content);
        // 存储到rabbitmq中
        rabbitMQService.sendDataToQueue("test",map);
        return "success";
    }
}
消费者
@Component
public class QueueListenter implements MessageListener {
    @Override
    public void onMessage(Message msg) {
        try{
            String content = new String(msg.getBody(), "UTF-8");
            System.out.println(content);
        }catch(Exception e){
            e.printStackTrace();
        }
    }
}

监听配置

    

  • tips
    queues:监听的队列,多个的话用逗号(,)分隔
    ref:监听器
消费者手动(安全)删除消息
@Component
public class QueueListenter implements ChannelAwareMessageListener {
         @Override
    public synchronized void onMessage(Message message, Channel channel) throws Exception {
        try{
            String content = new String(Message.getBody(), "UTF-8");
            System.out.println(content);
          // 删除rabbit队列消息
            channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
        }
        }catch(Exception e){
            e.printStackTrace();
        }
}
