This project is very new, and there is a lot more work to do. I encourage anyone interested in the functional approach to Spring to try it out and contribute.
Check it out on GitHub: https://github.com/wakingrufus/spring-funk

I would like to thank @sdeleuze for his great work on spring-fu which inspired this project.

10 years after the advent of #Spring, #SpringBoot shifted the paradigm from XML to Annotations. 10 years later, I believe it is time to shift the paradigm again, this time toward #FunctionalProgramming. On that note, I am excited to announce my new #OSS Project: Spring FunK
#SpringFunk provides easy access to Spring's beans and router DSLs and enables additional DSLs to be added. It works based on ApplicationContextInitializers, not AutoConfiguration, which allows for super fast startup. 🧵
