JSONobject inside JSONObject in java
I have following request mapping:
@RequestMapping(value = "/reCalculated", method = RequestMethod.POST)
public @ResponseBody void reCalculated(JSONObject obj) {
obj.
}
and then i have incoming json
{"params":{"date_a":"2017-05-01","date_b":"2017-05-02"}}
but in java, obj. only gives me options toString() and toJSONString()
meanwhile all the tutorials, and few threads clearly tell me i should be able to do obj.getJSONObject("params") Why is this? how can i access my parameters?
<dependency>
<groupId>com.googlecode.json-simple</groupId>
<artifactId>json-simple</artifactId>
<version>1.1.1</version>
</dependency>
is the dependency.

Why are you not considering defining a POJO data model and map the @RequestBody to it?

json-simple library had method get(String name) and need external type casting like below
String name = (String) jsonObject.get("name");
JSONArray msg = (JSONArray) jsonObject.get("messages");
long age = (Long) jsonObject.get("age");
But gson library has predefined methods here
public JsonObject getAsJsonObject(String memberName)
public JsonArray getAsJsonArray(String memberName)
Maven dependency

You can get JSONString from your param
Gson gson = (new GsonBuilder()).create();
jsonString = obj.get("params").getAsString();
JsonObject param= gson.fromJson(jsonString, JsonObject.class);
As Deadpool said, you want to use gson but you added json-simple dependency.
