MQProducer及MQProducerImpl

/** * * @author xuexiaolei * @version 2017年08月22日 */public interface MQProducer {    public void sendDataToQueue(String queueKey, Object object);}

import org.springframework.amqp.core.AmqpTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;/** * * @author xuexiaolei * @version 2017年08月22日 */@Servicepublic class MQProducerImpl implements MQProducer{    @Autowired    private AmqpTemplate amqpTemplate;    public void sendDataToQueue(String queueKey, Object object) {            amqpTemplate.convertAndSend(queueKey, object);    }}

QueueListenter

运行测试

/** * * @author xuexiaolei * @version 2017年08月22日 */@RunWith(value = SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {                "classpath:/application-mq.xml"})public class MQProducerImplTest {    @Autowired MQProducer mqProducer;    final String queue_key = "test_queue_key";    @Test public void sendDataToQueue() throws Exception {        Map<String,Object> msg = new HashMap();        msg.put("data","hello,rabbmitmq!");        mqProducer.sendDataToQueue(queue_key, msg);    }}

问题小记

默认的guest用户只能访问“/”的virtualHost，访问其他的virtualHost会出现下面的错误
