In light of the Java 8 Stream APIs and with lombok annotation processor library, I am no longer using this mapping frameworks. I create my own mappers by implementing the Converter interface of the spring framework (package org.springframework.core.convert.converter.Converter)

    @Component
    public class ProductToProductDTO implements Converter<Product, ProductDTO> {
        @Override public ProductDTO convert( Product source ) {
            ProductDTO to = ProductDTO.builder()
                    .name( source.getName())
                    .description( source.getDescription() )
                    .tags(source.getTags().stream().map(t -> t.getTag().getLabel()).collect( Collectors.toList()))
                            .build();
            return to;
        }
    }

    @Builder //lombok annotation to create Builder class
    @Data //lombok annotation to create getters & setters
    @AllArgsConstructor //required for @Builder
    public class ProductDTO  {
        private String name;
        private String description;
        private List<String> tags;
    }
