2.发送消息

public void send(Object message, Map<String, Object> map) {
　　MessageHeaders messageHeaders = new MessageHeaders(map);
　　Message<?> msg = MessageBuilder.createMessage(message, messageHeaders);
　　rabbitTemplate.setConfirmCallback(confirmCallback);
　　CorrelationData correlationData = new CorrelationData(UUID.randomUUID().toString());
　　rabbitTemplate.convertAndSend("miaosha_exchange", "zyh.miaosha", msg, messagePostProcessor, correlationData);
}

3.接收消息

@RabbitHandler
@RabbitListener(queues = {"miaosha_queue"})
public void onMessage(Message message, Channel channel) throws IOException {
    String o = (String) message.getPayload();
    boolean store = ordersService.store(o);
    if (store) {
        channel.basicAck((Long) message.getHeaders().get(AmqpHeaders.DELIVERY_TAG), true);
        System.out.println("消费成功");
    }else{
        channel.basicNack((Long) message.getHeaders().get(AmqpHeaders.DELIVERY_TAG),true,false);
        //
        System.out.println("消息被拒绝");
    }
}
