in spring boot, what's better? using multiple repositories in one service or using multiple services in one controller?

Question

I am trying to make this rest endpoint: /api/Offers/{offerId}/comments , what is better in design view?

• using CommentRepository and OfferRepository inside OfferService OR
• using CommentService and OfferService inside OfferController

It is sort of specific to general issue, I don't know what is most recommended approach!

Answer 1

I would pick the second variant:

using CommentService and OfferService inside OfferController

There is no special reason for that, but for me its clearer, other than the repositories. (Only my Opinion)
