ModelMapper: matches multiple source property hierarchies

Question

I cannot resolve modelMapper error. Do you have any ideas where is the issue?

NB: In view java.sql.Time doesn\'t have non-argument constructor I didn\'t find the better

Answer 1

I am not sure how it was with ModelMapper when question was asked but using converter should be straightforward. Instead of implementing a converter for the whole class implement it to the types that actually need conversion. So like:

public static Converter<LocalTime, Time> timeConverter = new AbstractConverter<>() {
    @Override
    protected Time convert(LocalTime source) {
        return null == source ? null : Time.valueOf(source);
    }
}; 

Then it is just to:

mm.addConverter(timeConverter);

Guess if using Spring or EJB you know howto add this into your configuration.

Answer 2

This resolved my problem: modelMapper.getConfiguration().setAmbiguityIgnored(true);

Answer 3

try modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT)

Answer 4

You need to customize ModelMapper configuration during Bean initialization with the help of a PropertyMap: http://modelmapper.org/user-manual/property-mapping/

@Bean
public ModelMapper modelMapper(){
    ModelMapper mm = new ModelMapper();

    PropertyMap<CarWashDTO, CarWash> propertyMap = new PropertyMap<CarWashDTO, CarWash> (){
        protected void configure() {
            map(source.getId()).setId(null);
        }
    }

    mm.addMappings(propertyMap);
    return mm;
}
