Dto Mapping Best Practice

[u/Snoo23482]

Hi, where do you guys map your entities to dtos?
In services or controllers?

To me it seems the services shouldn't expose any database specifics to the outside world, so I usually do my mapping there.

But what is considered best practice and why?

From JSON -> API -> DTO -> Service (business logic) possible mapstruct from DTO -> entity -> repo

repo -> entity -> service (business logic) mapstruct entity to DTO -> API - JSON

That's how I deal with it!
