Try to store servlet request to rabbitMQ

[Li ZW]

Recently， I try to make a web application(java and spring platform) . In the server side, I want to process the servlet request in a asynchronous way.

And I want to try using Rabbit MQ to implement this. But when I am working on it, I find it's difficult to send a HttpServletRequst object to rabbitmq.

My message convert is Jackson2JsonMessageConverter.

And below is my produce code

    public void sendDataToQueue(String queueKey, Object msgObj){
        try{
            amqpTemplate.convertAndSend(queueKey, msgObj);
        }  catch (Exception e) {
            e.printStackTrace();
        }
   }

Does anyone have idea about it ? 

Is it  appropriate to use RabbitMQ here to process asynchronous request ? Thanku

You haven't posted any exception stack traces but my guess is that serializing an HttpServletRequest to JSON will

fail.

Construct your own POJO (or a map) that Spring can convert to JSON and send it over, not HTTP/app server

requests.

About Spring and RabbitMQ integration I suggest to read this post:
https://spring.io/blog/2012/05/14/spring-mvc-3-2-preview-adding-long-polling-to-an-existing-web-application

It shows how to use DeferredResult class, very useful to make async calls.
