Si je vérifie le code généré, le createdDate et lastModifiedDate n'utilisent pas la méthode DateFormatConversion.class withDateFormatConversion.

Mais il a défini la dernière date modifiée avec un format de date simple comme

hospitalDetails.setLastModifiedDate( new SimpleDateFormat().parse( hospitalDetailsDTO.getLastModifiedDate() ) );

pourquoi le fichier généré impl ne choisit pas DateFormatConversion.class pour mapper le createdDate et le lastModifiedDate?

Answer 1

Le JavaDoc de type Annotation Mapper dit à propos de l'attribut "uses":

Autres types de mappeur utilisés par ce mappeur. Il peut s'agir de classes manuscrites ou d'autres mappeurs générés par MapStruct.

Votre Bean "DateFormatConversion" peut ne pas être identifié comme une classe de mappage manuscrite.
Vous pouvez également créer une interface annotée @Mapper DateFormatConversion et fournir une méthode par défaut avec le même code que dans votre méthode withDateFormatConversion.
