This version is still in development and is not considered stable yet. For the latest stable version, please use Spring Framework 6.2.0!

Requirements

Spring Framework supports Kotlin 1.7+ and requires kotlin-stdlib and kotlin-reflect to be present on the classpath. They are provided by default if you bootstrap a Kotlin project on start.spring.io.

The Jackson Kotlin module is required for serializing or deserializing JSON data for Kotlin classes with Jackson, so make sure to add the com.fasterxml.jackson.module:jackson-module-kotlin dependency to your project if you have such need. It is automatically registered when found in the classpath.
