Map multiple sources to a single destination

[Udi Ben Amitai]

Hi,

I just started using ModelMapper, so I'm sorry if this a trivial question.

I want to map multiple domain object to a single DTO object:

    public class Name{

        private String name;

    }

    public class Id{

        private String id;

    }

    public class Dto{

        public String name;

        public String id;

    }

(Assume getter/setters..)

I want to map both types (Name and Id) to the Dto.

The type mapping  (and even the mapping) works fine:

modelMapper.createTypeMap(IdObj.class, Dto.class);

modelMapper.createTypeMap(NameObj.class, Dto.class);

But validate() fails as it expect each of the sources to fulfill all destination's fields.

Is that the recommended practice for such case?

Is there a way (configuration?) to make validation ignore missing properties in the destination?

Thanks,

Udi

Hi Udi,

In this case validate won't work since all of the destination properties won't be fulfilled by a single source type. You can certainly map this scenario though:

Dto dto = modelMapper.map(IdObj.class, Dto.class);

modelMapper.map(NameObj.class, dto);

Cheers,

Jonathan
