java - Gson: Is there an easier way to serialize a map - Stack Overflow

Only the TypeToken part is neccesary (when there are Generics involved).

Map<String, String> myMap = new HashMap<String, String>();  myMap.put("one", "hello");  myMap.put("two", "world");    Gson gson = new GsonBuilder().create();  String json = gson.toJson(myMap);    System.out.println(json);    Type typeOfHashMap = new TypeToken<Map<String, String>>() { }.getType();  Map<String, String> newMap = gson.fromJson(json, typeOfHashMap); // This type must match TypeToken  System.out.println(newMap.get("one"));  System.out.println(newMap.get("two"));

Output:

{"two":"world","one":"hello"}  hello  world
