Spring Cloud Function has a couple of new features in 2.0 (still in milestone phase), and possibly the most dramatic is the ability to go "fully functional". This is made possible by changes in Spring Boot 2.1 together with Spring Framework 5.1, and it means a different way of thinking about bean definitions in Spring applications, but also significant improvements in startup performance.

AWS Cost Savings

It’s always good to start with a picture, especially if it tells a story. Here’s a graph that shows the improvement in Spring Cloud Function 2.0 over 1.0, comparing the cost of cold starts in…

I'm a long-time Spring developer, and I've advocated for it for the last 10 years. It's no surprise how widely adopted it is. Spring Boot dominates the Cloud Native Java ecosystem. Download numbers keep growing at unseen rates. In fact, according to the survey, there are more people developing using Spring technologies than not. It's a great time to be a Java developer!

I could be happier though…

The following CVEs have been published today:

1. CVE-2018-15756 for Spring Framework 5.1.1, 5.0.10, and 4.3.20.
2. CVE-2018-15758 for Spring Security OAuth 2.3.4, 2.2.3, 2.1.3, and 2.0.16.

Please, review the information, including affected project versions, in the CVE reports and upgrade immediately.

Spring Boot Users: Spring Boot 2.0.6 and 1.5.17, released earlier today, contain the fixes for the above vulnerabilities.

• Happy Ada Lovelace day! As you know, we name each Spring Data release train after a prominent computer scientist. This one is named for Ada Lovelace, an English mathematician and writer, she was chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. Once you're done reading more into this hero and this self described "poetical scientist", you might also read up on the new features our current Spring Data Lovelace release train…

Bienvenidos a todos a la edición inaugural de Spring Noticias en Español!!

Primero, una introducción. El español es el segundo o cuarto idioma más hablado en el mundo, de acuerdo a las estadísticas…​y Spring es la marca más popular de Java en el mundo. Hasta ahora, no ha existido una manera consistente de compartir los proyectos (videos, artículos, etc.) entre la comunidad de Spring de hispanohablantes. Todos juntos, podemos cambiar eso!

Periódicamente, publicaré noticias de tus proyectos escritos o grabados en español aquí. Ayúdame a extender tu voz y compartir tus conocimientos por todo el…

I take the opportunity of a short stop between SpringOne platform where I gave the first talk about Spring Fu and Kotlinconf to give an overview of the evolution of this project, summarize the current status and share what could be the next steps.

Early June, I announced a new experimental project named Spring Fu, with the goal to experiment on a new kind of API to configure Spring applications using Kotlin DSL and functional configuration.

Today, I am proud to announce a new experimental project: Spring Fu. It is a @Kotlin micro-framework that makes it easy to create lightweight Spring-powered applications with functional APIs instead of annotations. We are looking for feedback. https://t.co/R15wJ1gD8K pic.twitter.com/ScljoPZ8rW

I must admit I was not expecting the huge wave of feedback that followed, and I would like to thank the Spring community for such warm welcome. I have…

Whew! What a week! I'm exhausted! I've been running around visting one customer after another this week and it's only Tuesday! My brain is still a smoldering hole from the craziness of last week's epic SpringOne Platform 2018 event in Washington DC, and needless to say there's a ton of new things to investigate and tons of videos to be available to the audience soon. This week is a wee bit more tame, so without further ado, let's get to it!

I don't know where you are in the world as you read this but I hope you'll join me 17:00 BST, for my appearance at the vJUG where I'll be looking at Bootiful Testing…
