springcloud使用RibbmitMq延迟消息队列

1.第一步

/** * 设置消息的失效时间 */

public class DelayMessagePostProcessor implements MessagePostProcessor {

    private long ttl = 0L;

    public DelayMessagePostProcessor(long ttl) {
        this.ttl = ttl;
    }

    @Override
    public Message postProcessMessage(Message message) throws AmqpException {
        message.getMessageProperties().setExpiration(Long.toString(ttl));
        return message;
    }

}

2.第二步

/** * 设置消息的转化体 */

/** 消息发送队列 延迟缓冲（按消息） */
public static final String QUEUE_DELAY_PER_MESSAGE_TTL_MSG_SEND = "delay:per:message:msg:send";
/** 消息发送队列 DLX */
public static final String DLX_MSG_SEND = "msg:send:dlx";
/** 消息发送 1.短信 2.站内信 **/
public static final String QUEUE_MSG_SEND = "msg:send";

/**
 * 短信发送队列
 * @return
 */
@Bean
public Queue msgQueueDelayPerMessageTTL() {
    return QueueBuilder.durable(QUEUE_DELAY_PER_MESSAGE_TTL_MSG_SEND)
            .withArgument("x-dead-letter-exchange", DLX_MSG_SEND)
            .withArgument("x-dead-letter-routing-key", QUEUE_MSG_SEND)
            .build();
}

/**
 * 延迟短信交换定义
 * @return
 */
@Bean
public DirectExchange msgDelayExchange(){
    return new DirectExchange(DLX_MSG_SEND);
}

/**
 * 绑定
 * @param msgQueue          消费队列
 * @param msgDelayExchange  DLX
 * @return
 */
@Bean
public Binding smsDelayBinding(Queue msgQueue, DirectExchange msgDelayExchange) {
    return BindingBuilder.bind(msgQueue)
            .to(msgDelayExchange)
            .with(QUEUE_MSG_SEND);
}

第三步

消息队列服务端消费

@Component
@RabbitListener(queues = QUEUE_MSG_SEND)
public class MsgReceiver {

    private Log log = LogFactory.getLog(MsgReceiver.class);

    @Resource
    private MsgService msgService;

    @Resource
    private MemberUserService memberUserService;

    private ObjectMapper mapper = new ObjectMapper();



    @RabbitHandler
    public void process(Msg msg) {
        try {

            log.info("-----消息发送开始------");
            log.info(mapper.writeValueAsString(msg));
            msgService.sendMsg(msg);  //短信发送
            log.info("-----消息发送结束------");
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }
}

Msg msg = new Msg();
msg.setMemberId("1");
msg.setType(17);
amqpTemplate.convertAndSend(QUEUE_DELAY_PER_MESSAGE_TTL_MSG_SEND, msg, new DelayMessagePostProcessor(100));
System.out.println(UF.getFormatDateTime(UF.getDateTime()));
