CompanyMapper

@Mapper(uses=EmployeeMapper.class)
public interface CompanyMapper {
    CompanyDto companyToDto(Company company);
}

public class CompanyMapperImpl implements CompanyMapper {

    private final EmployeeMapper employeeMapper = Mappers.getMapper( EmployeeMapper.class );

    @Override
    public CompanyDto companyToDto(Company company) {
        if ( company == null ) {
            return null;
        }

        CompanyDto companyDto = new CompanyDto();

        companyDto.setEmployees( employeeMapper.employeesListToDto( company.getEmployees() ) );

        return companyDto;
    }
}

CompanyMapper with a specific CollectionStrategy 

@Mapper(uses= EmployeeMapper.class, collectionMappingStrategy= CollectionMappingStrategy.ADDER_PREFERRED)
public interface CompanyMapperAdderPreferred {
    CompanyDto companyToDto(Company company);
}
