== Extensions
Thanks to its great https://kotlinlang.org/docs/reference/java-interop.html[Java interoperability]
and to https://kotlinlang.org/docs/reference/extensions.html[Kotlin extensions], Spring
Framework Kotlin APIs leverage regular Java APIs and are additionally enhanced by a few Kotlin specific APIs
available out of the box within Spring Framework 5 artifacts.
Kotlin https://kotlinlang.org/docs/reference/extensions.html[extensions] provide the ability
to extend existing classes with additional functionality. The Spring Framework Kotlin APIs make
use of these extensions to add new Kotlin specific conveniences to existing Spring APIs.

and documents all the Kotlin extensions and DSLs available.

this specific Kotlin feature can prevent the application from starting, if this fact is not taken in
consideration. This is because Spring beans are normally proxified with CGLIB
- such as `@Configuration` classes - which need to be inherited at runtime for technical reasons.
The workaround was to add an `open` keyword on each class and member
functions of Spring beans proxified with CGLIB such as `@Configuration` classes, which can
quickly become painful and is against Kotlin principle to keep code concise and predictable.
Before Kotlin 1.0.6, one needed to add an `open` keyword on each class and member
functions of Spring beans proxified with CGLIB such as `@Configuration` classes.
Fortunately, Kotlin 1.0.6+ now provides a

http://start.spring.io/#!language=kotlin[start.spring.io] enables it by default, so in practice
you will be able to write your Kotlin beans without any additional `open` keyword, like in Java.
