                String json = "{\"name\":\"tbc\", \"age\":20}";
                Map<String, Object> map = new HashMap<String, Object>();
                // convert JSON string to Map
                map = mapper.readValue(json, new TypeReference<Map<String, String>>(){});
            } catch (JsonGenerationException e) {
