https://kotlinlang.org[Kotlin] is a statically typed language that targets the JVM
(and other platforms) which allows writing concise and elegant code while providing
very good https://kotlinlang.org/docs/reference/java-interop.html[interoperability]
with existing libraries written in Java.

The Spring Framework provides first-class support for Kotlin and lets developers write
Kotlin applications almost as if the Spring Framework was a native Kotlin framework.
Most of the code samples of the reference documentation are
provided in Kotlin in addition to Java.

The easiest way to build a Spring application with Kotlin is to leverage Spring Boot and
its https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-kotlin.html[dedicated Kotlin support].
https://spring.io/guides/tutorials/spring-boot-kotlin/[This comprehensive tutorial]
will teach you how to build Spring Boot applications with Kotlin using https://start.spring.io/#!language=kotlin&type=gradle-project[start.spring.io].
