Hi Spring fans! Welcome to another installment of This Week in Spring! I just finished an online training today, Bootiful Kotlin, for O'Reilly today, and I'm doing another one on the 2nd of August (this Thursday), Reactive Spring, because the demand for the first one was so high. Don't miss it!

We've got a ton of things to look at, so without further ado, let's get to it!

• A friendly reminder that our Spring YouTube channel is awesome! There's so much good stuff and it's easy to get back to it. Just go to spring dot io dot video

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in San Francisco in studio with Spring Security lead Rob Winch filming our new Spring Security Livelessons video. There is so much to cover that, as you can imagine, it's a tall order even for the two of us!

I'm also busily preparing for my talk with my buddy and Googler Ray Tsang at this week's Google Cloud NEXT event on all things Pivotal and Google Cloud. We're going to look at the bootiful Spring Cloud GCP project and, importantly, the new project jointly announced between Google and Pivotal just this morning, KNative, which serves as the platform on which we at Pivotal have built and deployed our Project Riff serverless function-as-a-service runtime. Do not…

Now, without further…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in sunny (warm!) Los Angeles for the epic SpringOne Tour Los Angeles event and then it's off to Boston for meetings. We've got a lot to cover, as usual, so let's get to it!

Today it is with an optimistic look to the future that I am announcing the end of life for Spring Social, a project that I have had the pleasure to work with over the past eight years.

With the release of Spring Security 5, much of the functionality offered by Spring Social’s connection framework—which I consider the most valuable piece of Spring Social—is now part of Spring Security. In fact, I shared how to use Spring Security’s new support for client-side OAuth2 in a blog article from back in March. And as Spring Security continues to evolve its client-side OAuth support, Spring Social’s…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm fresh of the amazing Spring Connect São Paulo event and speaking with some customers, and now I'm in beautiful Rio de Janeiro soaking up the winter rays by he beach, connecting with people in the community, and delivering a (virtual!) 2 day live training course for O'Reilly on building cloud-native Java-based applications. In less than two days I'll be home for the first time in almost a month to celebrate the 4th of July. If you're in America, let me be the first to wish you a happy holiday. As usual, we've…

With MongoDB 4.0, ACID transactions have arrived in the Document store, enforcing all-or-nothing execution and maintaining data integrity. So, let’s get straight to it by looking at both the synchronous and the reactive execution models.

At the time of this writing, MongoDB multi-document transactions are supported across a single replica set and feel like the transactions you are probably familiar with from relational databases. Looking at the driver API, one feels immediately at home:

try (ClientSession session = client.startSession()) {

    session.startTransaction();

    try…
