Convert JSON to Map

Question

What is the best way to convert a JSON code as this:

{ 
    \"data\" : 
    { 
        \"field1\" : \"value1\", 
        \"field2\" : \"value2\"
    }
}
         


        

Answer 1

With google's Gson 2.7 (probably earlier versions too, but I tested 2.7) it's as simple as:

Map map = gson.fromJson(json, Map.class);

Which returns a Map of type class com.google.gson.internal.LinkedTreeMap and works recursively on nested objects.
