我正在使用 ModelMapper 將 JPA 實體映射到 DTO。我在實體上有集合 dto 是由 wsimport 從 wsdl 文件生成的，但不會生成集合的設置器public class sampleEntity{    private String name;    private Collection<String> list;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }        public Collection<String> getList() {        return list;    }    public void setList(Collection<String> list) {        this.list = list;    }}public class sampleDTO{    private String name;    private Collection<String> list;    //getters & setters    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Collection<String> getList() {        return list;    }//no collection setters with jaxb!!! Use getList().add()}我使用一個簡單的 MapperUtils 來映射實體和 dtopublic class MapperUtils {    private static ModelMapper modelMapper = new ModelMapper();    static {        modelMapper = new ModelMapper();        modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.LOOSE);    }    private MapperUtils() {    }    public static <D, T> D map(final T entity, Class<D> outClass) {        return modelMapper.map(entity, outClass);    }    public static <D, T> List<D> mapAll(final Collection<T> entityList, Class<D> outCLass) {        return entityList.stream().map(entity -> map(entity, outCLass)).collect(Collectors.toList());    }    public static <S, D> D map(final S source, D destination) {        modelMapper.map(source, destination);        return destination;    }}那么如果Entity.XXXX是一個Collection，如何使用ModelMapper來使用DTO.getXXXX.add()呢？
