Hi, I'm starting a Kotlin Backend + Spring Boot and don't know what DI framework use, which do you recommend?

Doesn't Spring have DI built-in?

It definitely does. If you're using Spring Boot, then you already have everything in the Spring Framework along with easier configuration based on what Boot starters you bring in.

oh, that's right, thanks!! i'll try it

Also ask yourself - do you actually need a DI framework?

That moment you realize Spring framework has grown so large in features when someone asks this… 😂

Spring has always covered many things, and that's why it is so many modules. So you can pick and choose what you want. As to the 'Do you actually need a DI framework?', I suspect that the way most people define their classes, they DO NOT. But if you're using Spring Boot/Spring Framework, it assumes you will be using it so that you can access all the items that have been auto-configured, or easily configured using properties. So if you've chosen Spring Boot, you've almost implicitly chosen to use DI.

thanks for all the answers!
