   Spring Boot with Kotlin, functional configuration and GraalVM

Conference

Programming languages
Programming languages
Beginner & novice level
Room 7 Wednesday from 15:10 til 16:00

In this talk, I will live code a Spring Boot application with no annotation that will run as a native executable compiled with GraalVM. This application will leverage Kofu configuration, a Kotlin DSL designed to configure your application in a functional way.

I will also present various features currently incubated in Spring Fu project:

  • Kofu (Kotlin DSL) and Jafu (Java DSL) configuration for Spring Boot
  • Minimal set of features enabled by default
  • No classpath scanning, no feature enabled based on classpath detection
  • Both declarative (via the DSL) and programmatic (code auto-complete, allow any kind of if, for statements)
  • Functional configuration based on pure lambdas
  • Minimal reflection usage, no CGLIB proxy, no annotation processing
  • Faster startup and lower memory consumption
  • GraalVM native images support
  • Reactive SQL via R2DBC
  • Coroutines web and persistence API

I will explain where we are, what we learnt, and what's coming next in term of new Spring Framework and Spring Boot features.
