Hi Spring fans! This week I'm in Crete, Greece, for the epic JCrete un-conference and then it's off to Istanbul, Turkey for next week's visits with customers and for the Spring meetup. I hope you'll join me in Istanbul!

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

• Spring Integration ninja Artem Bilan just announced the Spring Integration Extension for Hazlecast 1.0.0.GA. This new release features mainly bug fixes and improvements. It also adds support distributed, clustered applications with implementations of HazelcastMessageStore, HazelcastLockRegistry, and HazelcastMetadataStore.
• Spring Security ninja Joe Grandja just announced Spring Security OAuth 2.2.0.RC1. This new release includes improvements to the way JWT tokens and claim sets are handled. Do not miss the update!
• Want to profile Java applications on Cloud Foundry…

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in Minneapolis, Minnesota; Kansas City, Kansas; and Phoenix, Arizona talking to customers and Pivotal partners about all things Spring and Cloud Foundry. If you're around don't hesitate to say hi!

We've got a lot to cover this week, so let's get started!

• Mark Fisher debuted the first look at Spring Cloud Function, an abstraction that brings the function-as-a-service paradigm to your Spring applications. This is a must-read!
• Spring (big-)Data ninja Thomas Risberg just announced Spring for Apache Hadoop 2.5.0 GA which mostly includes bugfixes and dependency updates.
• Spring Cloud co-founder just announced the first milestone of Spring Cloud Finchley. This release is the first to be based on the upcoming Spring Boot 2.0 baseline with one major new feature: a new microproxy called Spring Cloud Gateway which we see as a replacement for Zuul 1.
• Spring Tool Suite 3.9.0 released…

Spring Cloud Function is a new project with the following high-level goals:

• Promote the implementation of business logic via functions.
• Decouple the development lifecycle of business logic from any specific runtime target so that the same code can run as a web endpoint, a stream processor, or a task.
• Support a uniform programming model across serverless providers, as well as the ability to run standalone (locally or in a PaaS).
• Enable Spring Boot features (auto-configuration, dependency injection, metrics) on serverless providers.

Just as Spring has always promoted a plain old java object (POJO) based programming model, Spring Cloud Function promotes a programming model based on plain old functions. By that we mean the core interfaces defined in the java.util.function package: Function, Consumer, and Supplier…

Welcome to another installment of This Week in Spring! If you're in the US, then let me wish you a happy 4th of July! We've got a lot to cover so let's get to it!

• The Spring Framework Guru web portal has an interesting look at what's new in Spring Framework 5! Check it out!
• I liked this post on Bozho's Tech Blog on setting up the epic Spring Boot Admin for monolithic applications, eschewing some of the more common, albeit more complex, setups.
• our friend Petri Kainulainen is back at it again this time with a new newsletter that looks to capture…

Hi Spring fans and welcome to another installment of This Week in Spring! This week I'm in Krakow, Poland for the epic Devoxx PL event and then it's off to Luxembourg for the VoxxedDays Luxembourg event! If you're around, don't hesitate to say hi

Dear Spring Community,

Last month, Spring Session lead Rob Winch announced the release of Spring Session 2.0.0.M1 (notice the lack of MongoDB there?) In that post, he pared back Spring Session to officially supporting Redis, JDBC, and Hazelcast. No more MongoDB.

I’m here to announce that I’ve pick up the torch for Spring Session MongoDB. Managing both Spring Session and Spring Security (among other responsibilities), Rob couldn’t maintain high caliber support with too many data stores. Being a member of the Spring Data team, I felt better suited toward providing MongoDB support of Spring Session, so I reinstated it as a separate project…

Hi Spring fans! This week I'm in Redmond, hanging out with our friends and Pivotal partner Microsoft talking about Cloud Foundry on Microsoft Azure. As you may know, Microsoft's Azure IaaS platform is the #2 most widely used cloud and it's growing! It's got more datacenters than the other two cloud vendors in more regions (including in Germany and China!) and a huge raft of services that support both Windows and Linux operating systems. There's so much exciting stuff coming up including Azure Stack, which runs Azure on-premise, and the amazing integration between Azure and PCF. I'm looking…
