Mapping Map to DTO object using Jackson Object Mapper

In my controller I am getting a Map which I am mapping to my DTO object using Jackson Object Mapper. Now I have an added condition in my api which needs another value(viewType) to be sent in Map which is not a field in DTO. How do I manage to send viewType in map along with DTO fields without getting Error: Exception thrown -Unrecognized field "viewType"

Below is how I am mapping Map to DTO

 ObjectMapper mapper = new ObjectMapper();
  RetrieveDTO retrieveDTO = mapper.convertValue(req, RetrieveDTO.class);

I tried following but still not working

mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
Solution

  • Instead of 

    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

    I tried 

    mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

    And it worked
