代码实现:

//首先rabbitAdmin的配置 @Bean public RabbitAdmin rabbitAdmin(CachingConnectionFactory cachingConnectionFactory){ RabbitAdmin rabbitAdmin = new RabbitAdmin(cachingConnectionFactory); rabbitAdmin.setIgnoreDeclarationExceptions(true); return rabbitAdmin; }

然后是队列交换机以及绑定的声明(Queue,Exchange,Binding)

@Autowired RabbitAdmin rabbitAdmin; /** * 创建延迟队列，该队列内容不会呗监听，TLL到期自动转发 * @param queueName * @param delayExchange */ public void createDelayQueue(String queueName,String delayExchange,String delayRoutingKey){ Map map = new HashMap<>(); /**注意这两个参数必须绑定**/ map.put("x-dead-letter-exchange", delayExchange); map.put("x-dead-letter-routing-key", delayRoutingKey); rabbitAdmin.declareQueue(new Queue(queueName,true,false,false,map)); } /** * 创建普通队列 * @param queueName */ public void createQueue(String queueName){ rabbitAdmin.declareQueue(new Queue(queueName,true,false,false,new HashMap<>())); } /** * 创建延迟队列得交换机，就是一个普通得交换机 * @param name */ public void createExchange(String name){ rabbitAdmin.declareExchange(new DirectExchange(name,true,false)); } /** * 绑定队列 * @param queueName * @param delayExchange * @param routeKey */ public void bindQueue(String queueName,String delayExchange,String routeKey){ rabbitAdmin.declareBinding(new Binding(queueName,Binding.DestinationType.QUEUE,delayExchange,routeKey,new HashMap<>())); } /** * 发送消息 * @param message * @param exchange * @param routeKey * @param tll 时间 单位毫秒 */ public void sendMessageWithTll(String message,String exchange,String routeKey,String tll){ rabbitAdmin.getRabbitTemplate().convertAndSend(exchange, routeKey, message, new MessagePostProcessor() {  @Override  public Message postProcessMessage(Message message) throws AmqpException {  message.getMessageProperties().setExpiration(tll);  return message;  } }); } @Override public void sendMessage(String message, String exchange, String routeKey) { rabbitAdmin.getRabbitTemplate().convertAndSend(exchange, routeKey, message, new MessagePostProcessor() {  @Override  public Message postProcessMessage(Message message) throws AmqpException {  return message;  } }); }

进行测试

/** * 监听消息 * @param message * @return */ @RabbitListener(queues = "consumerQueue") public void getMessage(String message){ System.out.println("收到消息getMessage:"+message +",time="+MyUtil.FormatDate(new Date())); }
