ModelMapper Records -> Entity Class mapped null

[Fox Tech]

Hello,

I just find out about ModelMapper and I am struggling to use it because It seems that it does not work Records -> Entity class. It only works DTO -> Entity class. Please see the example 

public static void test() {
ModelMapper modelMapper = new ModelMapper();
ReviewDTO reviewDTO = new ReviewDTO("222", "111", 2);
Review map = modelMapper.map(reviewDTO, Review.class);
System.out.println(map);
}

===========================================================

public record ReviewDTO(String title, String description, int starRating) {
}

============================================================

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Review {
@Id
@GeneratedValue(strategy = IDENTITY)
private Long id;
private String title;
private String description;
private int starRating;

@Override
public String toString() {
return "Review{" +
"id=" + id +
", title='" + title + '\'' +
", description='" + description + '\'' +
", starRating=" + starRating +
'}';
}
}

=============================================================

OUTPUT= Review{id=null, title='null', description='null', starRating=0}

\

Does anyone knows why? Is it just me or it does not work? I have searched on google and nothing.

Many thanks,

Fox.

I found a similar problem... it does not on final such as Records

hello

My problem was solved as follows, in the modelmapper it is necessary to traverse the object. In this case I did it this way.

public ConsultaDTO createConsulta(@RequestBody ConsultaDTO consultaDTO)
{
Query queryRequest = mapper.map(queryDTO, Query.class);
//clinic
consultaRequest.getConsultorio().forEach(c ->c.setNumero(c.getNumero()));
consultaRequest.getConsultorio().forEach(c ->c.setData_hora(c.getData_hora()));
//doctor
consultaRequest.getMedico().forEach(c ->c.setCrm(c.getCrm()));
consultaRequest.getMedico().forEach(c ->c.setEspecialidade(c.getEspecialidade()));
consultaRequest.getMedico().forEach(c ->c.setIdade(c.getIdade()));
consultaRequest.getMedico().forEach(c ->c.setNome(c.getNome()));

//Write to memory
Query query = consultaService.createConsulta(queryRequest);
// convert entity to DTO
return mapper.map(query, QueryDTO.class);
}


my project github is this one.

There is also a problem if you do not use this method. It is as follows, if you have this method the object is not inserted into the database, due to an id conflict.

public Long getAllId(){
return (id.equals(0) ? null:id);
}
