Spring into Kotlin: How to Make the Magic even more Magical
summary
Live demo migrates a working Spring Boot app to Kotlin: uses Spring Initializer, Gradle Kotlin DSL, embedded MongoDB (flapdoodle), Spring Data repository and a REST controller, seeds data with a CommandLineRunner lambda, and verifies endpoints with HTTP calls. Kotlin replaces constructors/getters with concise data class properties, adds null-safety and string templates, and reduces boilerplate so the app compiles and returns results. Uses IntelliJ conversion and shows Spring Boot + Kotlin running end-to-end.
