Understanding DTOs and entities in Spring Boot

Показать описание

Is it okay for your web controllers to return entity classes from the data access layer? Or should you decouple things using DTOs (data transfer objects)?

What are the tradeoffs? Does it really matter?

Find out in this live stream where Greg, principal developer on the Spring teams examines what's at stake and what impact it could have on your application.

Hi Greg,
came here while was reading your book Spring Boot 3.0.
There was a link in the Querying for Data chapter.
Both a book and the video are great.
Thank for your effort making our life simpler.
By the way, the background music is amazing :)

The music is extremely relaxing too, its like a therapy session

Hi Greg, nice video!
Going forward with these examples, how would you map the other way around? Lets say an EmployeDTO comes in from a post request and you want to convert it to Employee entity? Where would you put this 'mapping' ?

Sorry I do not understand the advantage of DTO vs entity. Could you explain a bit further?

The image flashing gave me a bit of a headache but thanks a lot, this explanation was great even for me as a beginner

Now I start to believe software design is art.

Wow your monitor is huge, what is it?

just started watching this, but so far it's difficult to hear you talking over the background music; the music is too loud/distracting
