This Week in Spring – Only Infotech22nd, 2018

Hi fans! Whew! What a wild week it’s been! I landed in Kiev, Ukraine, last Thursday to present at the epic JEEConf in beautiful Kiev. Then, this weekend it was off to Dublin, Ireland and Belfast, North Ireland, where I had the privilege of speaking to some of the amazing Pivotal customers (like Liberty). I concluded today here in Belfast and tomorrow it’s off to bella Barcelona, Spain for the Spring I/O conference.

As usual, it’s been a crazy awesome week in the Spring community so without further ado let’s get to it!

  • We now have OIDC Provider Configuration support in Spring Security Master. Awesome!
  • Be sure not to miss this webinar on what’s new in Spring Cloud Stream, June 7th, from Spring Cloud Stream lead Oleg Zhurakousky

  • Hi Spring fans! In last week’s installments of Spring Tips, I looked at Project Riff and Spring Cloud Function, a one-two punch for serverless function-as-a-service applications. Project Riff is a FaaS platform from Pivotal and Spring Cloud Function makes writing portable, Spring Boot-aware functions for a number of different platforms as easy as possible.

Anyway, get the bits while they’re hot!
