The docs show off a Kotlin DSL. It's used to configure an HttpSecurity to produce the SecurityFilterChain bean.

However, I had trouble getting this to work in my application so came to the look at the samples for help. Unfortunately, the "Hello Security" Kotlin sample doesn't use the DSL.

I'd love it if use of the Kotlin DSL was demonstrated in that sample application.

The Kotlin DSL seems to be the recommended way to configure Spring Security when you're using Kotlin, so I'd assume this would be broadly useful.
