我刚开始启动项目时报错，最后发现是由于缺少了jar包以及jar包版本不一致,我使用的是springboot 1.5.6,如果和我一样可以参考上面的，我本机测试是没问题的。不一样的话，可以自己去百度查看你使用的springboot版本对应的jar包版本号。

MQProperties.java

@Component@ConfigurationProperties(prefix = "mq")public class MQProperties {    private String topicExchange;    private String routeKey;    private String queue;    private String myQueue;    private String myRouteKey;    public String getMyQueue() {        return myQueue;    }    public void setMyQueue(String myQueue) {        this.myQueue = myQueue;    }    public String getMyRouteKey() {        return myRouteKey;    }    public void setMyRouteKey(String myRouteKey) {        this.myRouteKey = myRouteKey;    }    public String getTopicExchange() {        return topicExchange;    }    public void setTopicExchange(String topicExchange) {        this.topicExchange = topicExchange;    }    public String getRouteKey() {        return routeKey;    }    public void setRouteKey(String routeKey) {        this.routeKey = routeKey;    }    public String getQueue() {        return queue;    }    public void setQueue(String queue) {        this.queue = queue;    }}

RabbitMQConfig.java

@Component@EnableRabbitpublic class RabbitMQConfig {    @Autowired    private MQProperties mqProperties;    @Autowired    private CachingConnectionFactory connectionFactory;    /*这里的connectionFactory不需要手动创建，因为org.springframework.boot.autoconfigure.amqp.RabbitAutoConfiguration.RabbitConnectionFactoryCreator已经创建好了，只要你在application.yml中添加了相应的配置就可以了*/    @Bean    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)    public RabbitTemplate rabbitTemplate() {        return new RabbitTemplate(connectionFactory);    }    @Bean    public Queue queue1() {        return new Queue(mqProperties.getQueue());    }    @Bean    public Queue queue2() {        return new Queue(mqProperties.getMyQueue());    }    @Bean    public TopicExchange topicExchange() {        return new TopicExchange(mqProperties.getTopicExchange(), true, false);    }    @Bean    public Binding binding1() {        // *表示一个单词,#表示零个或多个单词        return BindingBuilder.bind(queue1()).to(topicExchange()).with(mqProperties.getRouteKey() + ".*");    }    @Bean    public Binding binding2() {        return BindingBuilder.bind(queue2()).to(topicExchange()).with(mqProperties.getMyRouteKey() + ".*");    }}

生产者 Sender.java

@Componentpublic class Sender implements RabbitTemplate.ConfirmCallback {    private RabbitTemplate rabbitTemplate;    @Autowired    private MQProperties mqProperties;    public Sender(RabbitTemplate rabbitTemplate) {        this.rabbitTemplate = rabbitTemplate;        rabbitTemplate.setConfirmCallback(this);    }    public void send1(String message) {        System.out.println("Sender1 : " + message);        rabbitTemplate.convertAndSend(mqProperties.getTopicExchange(), mqProperties.getRouteKey() + ".springboot",                message, new CorrelationData(UUID.randomUUID().toString()));    }    public void send2(String message) {        System.out.println("Sender2 : " + message);        rabbitTemplate.convertAndSend(mqProperties.getTopicExchange(), mqProperties.getMyRouteKey() + ".qinwei",                message, new CorrelationData(UUID.randomUUID().toString()));    }    @Override    public void confirm(CorrelationData correlationData, boolean ack, String cause) {        System.out.println(" 回调id:" + correlationData);        if (ack) {            System.out.println("消息成功消费");        } else {            System.out.println("消息消费失败:" + cause);        }    }}

消费者 Receiver.java

@Componentpublic class Receiver {    @RabbitListener(queues = "${mq.queue}")    public void receive1(Message message, Channel channel, String msg) {        System.out.println("消费内容为1: " + new String(message.getBody()));        try {            channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);        } catch (Exception e) {            e.printStackTrace();        }    }    @RabbitListener(queues = "${mq.myQueue}")    public void receive2(Message message, Channel channel, String msg) {        System.out.println("消费内容为2: " + msg);        try {            channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);        } catch (Exception e) {            e.printStackTrace();        }    }}

测试类 RabbitMqTest .java

@RestControllerpublic class RabbitMqTest {    @Autowired    private Sender sender;    @RequestMapping(value = "/rabbitmq/{message}", method = RequestMethod.GET)    public String hello(@PathVariable("message") String message) {        SimpleDateFormat sdf = new SimpleDateFormat("yyy-MM-dd HH:mm:ss.SSS");        String context = message + " " + sdf.format(new Date());        /*如果message为qinwei1则只发送到queue1；qinwei2只发送到queue2；qinwei12则同时发送到2个queue*/        if (message.contains("1")) {            sender.send1(context);        }        if (message.contains("2")) {            sender.send2(context);        }        return context;    }}
