Hi Spring fans! Welcome to another installment of This Week in Spring! What a wild and wonderful week of Spring it's been! This week I'm in London, UK for the epic SpringOne Tour event and customer visits, then I'm off to Vienna, Austria and then I'm off to Amsterdam, NL for the SpringOne Tour event there. If you're in any of these places please say hi!

Hi Spring fans! Welcome to another installment of a Bootiful Podcast! This week Josh Long (@starbuxman) talks to Joe Grandja (@joegrandja) who, not coincidentally, just celebrated his third anniversary working on the Spring team! Joe has been instrumental in building Spring Security 5.x and its OAuth client and resource-server support.

Hi Spring fans! Welcome to a super quick, intra-season interregnum installment of Spring Tips in which we look at a few features that let you be both lazy AND fast in Spring Boot 2.2!

speaker: Josh Long @starbuxman

The recently announced first milestone of Spring Boot 2.2 introduces support for lazy initialization. This post describes the new functionality and explains how and when to enable it.

What Does it Mean to be Lazy?

Spring Framework has had support for lazy bean initialization since before its source code moved to Git 11 years ago. By default, when an application context is being refreshed, every bean in the context is created and its dependencies are injected. By contrast, when a bean definition is configured to be initialized lazily it will not be created and its dependencies will not be…

Hi Spring fans! What a week! I'm in Seattle, Washington where I've been spending time with Pivotal partner Microsoft talking about all things Spring, Cloud Foundry and Azure, and then tonight I spoke at the Seattle Java User Group on Reactive Spring.

Tomorrow morning I'm off to jolie Montreal, Canada for the epic ConFoo conference. Are you going to be around? Say hi!.

Anyway, without further ado let's get to this week's roundup!

• Memory footprint of the JVM
• Spring Boot 2.2 M1
• A Bootiful Podcast: Matt Raible and James Ward at Devnexus 2019
• Spring Cloud Greenwich.SR1 is now available
• Spring Data Moore M2 released
• Has there ever been a better time to become a Java developer?
• Spring Cloud Data Flow and Skipper 2.0 GA Released
• I love this post on the nuances of assembly versus subscription in Reactor: Flight of the Flux (part 1)
• Good news everybody! Today marks the 30th anniversary of the World Wide Web! Tim Berners Lee, who created the HTTP web, has a stark warning for us worth our attention.
• This is an interesting third-party project that generates HTTP request snippets for SpringFox which integrates Swagger with Spring…

The JVM can be a complex beast. Thankfully, much of that complexity is under the hood, and we as application developers and deployers often don't have to worry about it too much. With the rise of container-based deployment strategies, one area of complexity that needs some attention is the JVM's memory footprint.

Two kinds of memory

The JVM divides its memory into two main categories: heap memory and non-heap memory. Heap memory is the part with which people are typically the most familiar. It's where objects that are created by the application are stored. They remain there until they are no…

Hi Spring fans! In this extra-long installment I talk with longtime friends and fellow developer advocates, Okta's Matt Raible and Google's James Ward. We talked about Java, Kotlin, Spring, cloud computing technologies, security, Go, paradigm changes, web frameworks past and present, Macromedia, Adobe, Scala, and a million more things! This was a ton of fun for me so I'm hoping you'll enjoy it too.

Surely there’s never been a better time to become a Java developer?

There are productivity tools available these days that would have been mind-blowing just five years ago.

Take Spring Boot for example. Many people reading this on the Spring website may be familiar with Spring Boot. But let’s take a moment to acknowledge its awesomeness.

Years ago, if you were going to use the Spring Framework in your application, you had to be OK with a certain amount of configuration toil creeping into your day. But it wasn’t nice friendly configuration like, (ah, actually, sorry, I can’t think of an example…

This blog post is the first in a series of posts that aim at providing a deeper look into Reactor's more advanced concepts and inner workings.

It is derived from my Flight of the Flux talk, which content I found to be more adapted to a blog post format.

I'll update the table below with links when the other posts are published, but here is the planned content:

1. Assembly vs Subscription (this post)
2. Debugging caveats
3. Hopping Threads and Schedulers
4. Inner workings: work stealing
5. Inner workings: operator fusion

If you're missing an introduction to Reactive Streams and the basic concepts of Reactor, head out to the site's learning section and the reference guide…
