Try this code:

  public static Map convertJsonIntoMap(String jsonFile) {
        Map map = new HashMap<>();
        try {
            ObjectMapper mapper = new ObjectMapper();
            mapper.configure(DeserializationFeature.UNWRAP_ROOT_VALUE, true);
            mapper.readValue(jsonFile, new TypeReference>() {
            });
            map = mapper.readValue(jsonFile, new TypeReference>() {
            });
        } catch (IOException e) {
            e.printStackTrace();
        }
        return map;
    }
