RabbitMQ设置消息过期时间：

Map map = new HashMap<>();
map.put("x-message-ttl",2000);
channel.queueDeclare(queueName,true,false,false,map);
channel.queueBind(queueName,exchangeName,"router.key");
channel.basicPublish(exchangeName,"message",null,"message".getBytes());

MessageProperties messageProperties = new MessageProperties();
messageProperties.setExpiration("600000");
byte[] msgBytes = rabbitJson1.toJSONString().getBytes();
Message message = new Message(msgBytes, messageProperties);
rabbitUtil.convertAndSend(mqConfig.getExBc(), "routtingkey", message);

3.设置队列过期时间:

Map map = new HashMap<>();
map.put("x-expires", 600000);
channel.queueDeclare(queueName, true, false, false, map);
channel.queueBind(queueName,exchangeName,"routtingkey");
