How to map same TO to new same TO in MapStruct?

My TO structure is as follows

OneComplexCto
-List<ComplexEto>
--List<SimpleEto>

I want to get it mapped with itself (for firing ValueChangeListener)

So I want to map like,

OneComplexCto mapOneComplexCto(OneComplexCto source, @TargetMapping OneComplexCto target);

It's just mapping like,

oneComplexCto.setComplexEtos(target.getComplexEtos);

and I want it to map all the nasted ComplexEto's and all the SimpleEto's inside those ComplexEto's. (Aparently I want to call the setters for each individual fields).

As you've noticed MapStruct will just invoke the setter in case the types are the same. In order to achieve a deep clone you would need to deifine mapping between all the types. In your case this would look like:

@Mapper
public interface ComplexMapper {

    OneComplexCto mapOneComplexCto(OneComplexCto source, @MappingTarget OneComplexCto target);

    List<ComplexEto> map(List<ComplexEto> complexEtos);

    ComplexEto map(ComplexEto complexEto);

    List<SimpleEto> map(List<SimpleEto> simpleEtos);

    SimpleEto map(SimpleEto simpleEto);
}

You should follow and upvote mapstruct/mapstruct-695 which looking for something to allow MapStruct to disable the direct set of the same types and perform deep clone.
