2017年以前采用的spring xml配置的方式，这里先回忆一下，现在采用yaml方式，

<dependency>
    	<groupId>org.springframework.amqp</groupId>
    	<artifactId>spring-rabbit</artifactId>
    	<version>2.0.1.RELEASE</version>
    </dependency>

#rabbitmq
    rabbitmq.addresses=192.168.5.130:5672,192.168.5.132:5672
    rabbitmq.username=admin
    rabbitmq.password=admin2015
    rabbitmq.concurrentConsumers=5  
    rabbitmq.channel.cache.size=50
    #
    rabbitmq.direct.exchange=mal-ms.direct.exchange
    rabbitmq.consumer.direct.exchange=eps.direct.exchange
    rabbitmq.ccs.direct.exchange=ccs.direct.exchange

消费侧的代码通过@RabbitListener来设定

import java.util.Date;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.amqp.rabbit.annotation.RabbitListener;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.messaging.handler.annotation.Header;
    import org.springframework.messaging.handler.annotation.SendTo;
    import org.springframework.stereotype.Component;
    
    @Component
    public class CcsQueueMal { 
    
    	private static final Logger logger = LoggerFactory.getLogger(CcsQueueMal.class);
    	@Autowired
    	private MalmsService malmsService;
    
    	/** * * @param id * 任务ID * @param type * 任务名称 * @return */
    	@RabbitListener(queues = "ccs.queue.mal")
    	public void ccsQueueListener(String id, @Header("jobName") String jobName) { 
    		logger.info("Received request for id " + id);
    		logger.info("Received request for job name " + jobName);
    		logger.info("定时任务执行时间:" + new Date());
    		// 返回执行结果（成功，失败）和ID
    		try { 
    			malmsService.cancelTimeOutChargeOrder();// 取消超时订单操作
    		} catch (Exception e) { 
    			logger.debug(e.getMessage(), e);
    		}
    	}
    }

从amqp中获取消息。

import java.io.UnsupportedEncodingException;
    import java.util.Date;
    import java.util.List;
    import java.util.Map;
    
    import org.springframework.amqp.core.Message;
    import org.springframework.amqp.rabbit.annotation.RabbitListener;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Component;
    @Component
    public class MsMQQueueListener { 
    @RabbitListener(queues = "eps.queue.report_status")
    	public void updateStatus(Message message) { 
    		String info = null;
    		try { 
    			info = new String(message.getBody(), "utf-8");
    		} catch (UnsupportedEncodingException e) { 
    			e.printStackTrace();
    		}
    		System.out.println(info);
    		Gson gson = new Gson();
    		Map<String, Object> map = gson.fromJson(info, Map.class);
    		String orderNo = map.get("orderNo").toString();
    		String logiNo = map.get("logiNo").toString();
    		String logistatus = map.get("status").toString();
    		}
    }

生产者

import org.springframework.amqp.core.AmqpTemplate;
    	@Autowired
    	AmqpTemplate template;
    	Map<String, String> map = new HashMap<String, String>();
    	map.put("orderNo", orderNo);
    	map.put("logiNo", epsLogiBill.getLogiNo());
    	map.put("status", LogiStatus.CREATED.status());
    	template.convertAndSend("eps.binding.report_status", map);
