:page-section-summary-toc: 1

{kotlin-site}[Kotlin] is a statically typed language that targets the JVM
(and other platforms) which allows writing concise and elegant code while providing
very good {kotlin-docs}/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 {spring-boot-docs-ref}/features/kotlin.html[dedicated Kotlin support].
{spring-site-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].

Feel free to join the #spring channel of https://slack.kotlinlang.org/[Kotlin Slack]
or ask a question with `spring` and `kotlin` as tags on
{stackoverflow-spring-kotlin-tags}[Stackoverflow] if you need support.
