Kotlin and the Spring Framework

Spring 5 and Spring Boot 2 includes support for components written in Kotlin. This talk will discuss how to implement Spring components, controllers, and services using Kotlin. Features will include the plugins necessary to open classes implemented in Kotlin for Spring proxying, using Kotlin object types, how to test Kotlin components, and using Kotlin with Spring Data.

Spring has always been very friendly to alternative JVM languages, and Kotlin is no exception. The Spring team has worked hard to provide Kotlin support throughout their ecosystem.
