How to pass json object as get parameter?

Question

Spring

I'm trying to pass json in a get request, it fails, apparently some type of data is needed that is not HashMap
http://localhost:8080/mesure/create?values={test: "test"}

@RequestMapping(value = "/create")
    public void setMesureId(@RequestParam(value = "values", required = false) HashMap<String, String> profileJson) {
}

Answer 1

GET -request involves getting data. If you need to send data, then do it using the POST method .

Answer 2

First, we need to serialize the transmitted data using URLEncode.
Secondly, you will need a converter that can turn the string into a HashMap.
in general, as i_visseri said , if you need to transfer some kind of payload, it is better to use POST requests.
