Question

I have application wide single controller.

@RequestMapping(method = RequestMethod.POST,value="services")
@ResponseBody
mwpWebServices(@RequestBody String data, HttpServletRequest request, HttpServletResponse response) throws JSONException, UnknownHostException, MongoException

{
    HttpSession session = request.getSession();

    ......

    String method = jsonObj.getString("method");

    ....

    if(method.equals("login"))
    {
        someClassObj.login(params);//which stores some value in session variable "somevar"
    }

    if(method.equals("other"))
    {
        System.out.println(session.getAttributes("somevar"));//coming null
    }
}

now “data” will recieve JSON String
and I will parse in into JSONObject that will look like
{“method”:”login”,”action”:”Auth”,”params”:”Some data”}

now when method is login

i call some method of another class to which I pass session object which store some value in session

but when next time when request comes, session varible doesn’t persist value…

Answer 1

HttpSession of requires the client i.e. Browser to store the session id in cookie.
So my browser’s cookie was off, that’s why each request was bringing new session id
