Current State

The current state of OAuth 2.0 Support, within the Spring projects portfolio, is spread out between Spring Security OAuth, Spring Cloud Security, Spring Boot 1.5.x, and the new support introduced in Spring Security 5. As a user of OAuth, you may be asking, "Which project(s) do I use? And why has Spring Security 5 introduced new support into the mix?"

To put it simply, there was a need to unify the OAuth 2.0 support into one project in order to provide a…

Aloha! This week I'm in sunny Honolulu for the first annual LavaOne conference. If you're not here, you should be! The show is amazing, enjoys 50% female to male audience attendance, the speakers are world-class (well, except yours truly, but don't tell them that..) and the location is pretty hard to beat!

That said, nothing gives me more pleasure than saddling up to a table with a laptop, some green tea, sunglasses and sunscreen lotion and checking in on the community. This week's been a heckuva week indeed! Lot's of great stuff so let's get to it!

• Project Reactor team ninja Simon Baslé offers a look at Reactor 3.2.M1

Greetings Spring community,

As previously announced, we have released a new Affordances API in 1.0.0.BUILD-SNAPSHOT. In this blog post, we’ll take a peek at exactly what this feature lets you do.

History of Affordances

For starters, what is an affordance? Doing a little archeology, Mike Admundsen, a REST advocate, has an article detailing the word’s origins, going back at least to 1986:

The affordances of the environment are what it offers …​ what it provides or furnishes, either for good or ill. The verb 'to afford' is found in the dictionary, but the noun 'affordance' is not. I have made it…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm off to Germany where I'll be speaking at the Java User Group in Münster on Wednesday night. Then, it's off to Solingen for a Cloud Native day on the 12th (this Friday) where I'll be presenting all afternoon - register now! And, if you're closer to the Pacific ocean than the Atlantic ocean, join me next Monday in Hawaii and we'll talk about all things Spring at the very promising LavaOne conference.

As usual, we've got a lot to cover so let's get to it.

• There's new support for auto-configuring the Reactor-based Cloud Foundry Java client in Spring Cloud. This is exciting for me because that Java client is such a powerful tool that takes so long to configure.
• There's a new guide on using Spring Cloud contract by community legend Erdem Günay.
• The Baeldung blog have a nice look at bootstrapping Hibernate 5 with Spring
• The first raft of Spring Days events have been announced! Do not miss these events in a city near you! I'll be there along with other Pivotal peeps. Join us.

This is the first roundup of the new year and so it is also the 7th year anniversary of my starting this column.

As usual, I'm always happy to have feedback and suggestions from you, the most amazing community ever! Don't hesitate to reach me on Twitter (@starbuxman) or by email…
