Spring and Kotlin: A match made in the JVM

In this session, we'll explore the combination of Spring and Kotlin, applying idiomatic Kotlin along with Spring's Kotlin extensions.

Spring has long been a framework that embraces simplicity and eschews unnecessary boilerplate and ceremony. Even so, Spring applications are commonly developed with Java which, as a language, demands a lot of boilerplate and ceremony. Although libraries such as Lombok help mitigate a lot of the unnecessary code, Lombok is sometimes viewed as a hack or “magic” that hides the ugly corners of Java.

Kotlin embraces simplicity and eschews unnecessary boilerplate and ceremony. Code written in Kotlin is much simpler and elegant than its Java equivalent, while remaining just as expressive.

It seems a natural fit to bring Spring and Kotlin together. In fact, Spring includes direct support for Kotlin, providing extensions that make writing Spring+Kotlin code a pleasant experience.
