Jeśli sprawdzę wygenerowany kod, createdDate i lastModifiedDate nie używają metody DateFormatConversion.class withDateFormatConversion.

Ale ustawił datę ostatniej modyfikacji z prostym formatem daty jako

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

dlaczego plik wygenerowany impl nie wybiera DateFormatConversion.class do mapowania createdDate i lastModifiedDate?

Answer 1

Dokument JavaDoc typu Annotation Mapper mówi o atrybucie „uses”:

Inne typy mapowania używane przez tego mapowania. Mogą to być klasy napisane odręcznie lub inne mapery generowane przez MapStruct.

Twoja Bean „DateFormatConversion” może nie zostać zidentyfikowana jako ręcznie napisana klasa mappera.
Możesz również utworzyć interfejs DateFormatConversion z adnotacjami @Mapper i zapewnić domyślną metodę z tym samym kodem, co w metodzie withDateFormatConversion.
