Handling json in url param

HI,
In my spring web application i am having the following code :
 @RequestMapping(value = "")
    public ModelAndView newNote(@RequestParam(value = "noteEvent", required = false) String noteEvent, HttpServletResponse response, HttpServletRequest request) throws IOException {

        ObjectMapper mapper = new ObjectMapper();
        String chatId = "";
        if(noteEvent != null) {
            Bun bun = mapper.readValue(noteEvent, Bun.class);
            chatId = bun.getChat();
        }

Open in new window

This is bascially a get request handler and url will have noteEvent param which is actually a json string :
"name":"sdfsd","button":"sdfsd","userId":"u:guid1","userName":"sdfsd","chat":"u:sdf","chatName":"Ben sdf"}

If the requestBody was a json string i could have directly used it as a param to the function and since spring auto performs the conversion i would have got an object withouth having to deal with this mapper thing.
But here as the noteEvent is a url param i had to resort to using this approach.
Dont know if there is a way in spring to handle this.

Please suggest a better approach if possible.

Thanks

I think the better approach would be to not have the JSON in the URL to begin with. As you mentioned, I would only have it as the request body. If you don't want in the body, then I would break out those JSON values into either URL query params or path params.
