REST API with Spring Boot and MongoDB using Kotlin

It’s true. When Google announced Kotlin as the preferred language for the Android platform, its overall popularity increased sharply.

In this text, I’d like to show you how easy it is to create a Spring application using Kotlin. I’m going to implement a simple CRUD REST API with Spring Boot and MongoDB as a database using Kotlin as a language.

So, get started with implementation and try it yourself.
