I want retrieve json from postgres sql and I will convert it to a plain string.
I want full json with json String.

DeviceProfile dp = device.getDp();

System.out.println("parameters Data:: "+dp.getParameters().toString());

JSONObject parameters = new ObjectMapper().readValue(dp.getParameters().toString(),JSONObject.class);

It will print following String which is wrong.

{Rs232=[{rs232unit=, parameterId=6, rs232ioindex=1.0, parametername=rs232}], Digital=[{reverse=true, dioindex=1.0, parameterId=1, parametername=Ignition}]}

I want proper json.

I am using jsckson api to parse data.

Are you sure dp.getParameters().toString() would return JSON?

Obviously, it doesn't. What makes you think it would? Is DeviceProfile one of your classes? I would start to look there.
