Hi, Spring fans! Welcome to another installment of This Week in Spring! How are you? You know what I've wanted to do? See my friends on the Spring team in person since the pandemic descended. And, I'm overjoyed to relate, I've just had the privilege of a nice meeting with several of them last night. And I'm going to see more of them today! Seriously. I feel like I won the lottery. I've missed my friends. Hug your friends and family, friends. You never know when the next pandemic (or life in general) will put distance between you and them. So, in order to close that distance, I'm going to go…

With the recent announcement of Spring Boot 3.0 going GA, some of you may be interested in upgrading your Spring Web Services-based applications to take full advantage of this. The Spring WS team has upgraded our set of sample apps to help you carry that out.

The main branch now tracks the version of samples with all these updates. (The prior version of samples built on Spring Boot 2.7 are now on that repository’s 1.0.x branch.)

Some of the highlights are covered below.

A LOT of our tools have moved!

Back in the olden days, much of our XML processing tools were inside the JDK. But ever since…

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to Java Champion Gunnar Morling (@gunnarmorling) about messaging middleware, Debezium, and more.

Hi, Spring fans! It's here! It's finally here, at long last! Spring Boot 3!! And of course with Spring Boot 3.0 comes a whole portfolio of integrated projects that have also been updated! Remember, a huge theme in this release is support for GraalVM native images, and that's now supported across the board. You know what to do: start.spring.io.

I put together a Spring Tipds video introducing some of the major themes of Spring Framework 6 / Spring Boot 3.

I also did an in-depth look at the new GraalVM support powered by Spring's ahead-of-time (AOT) engine.

There's so much else to talk about this week, but I really can't stress this enough: Spring Boot 3 is here! In some ways, it feels like this release has been more than four years in the making! It's amazing, and I can't wait for people…

Hi, Spring fans! Spring Boot 3 is here (or will be tomorrow, on the 24th of November, 2022, to be more precise!), bringing a fantastic new Ahead-of-Time (AOT) compilation engine that supports GraalVM native images. Join me, and we'll dive deep into the engine and its interactions with the Spring component model.

This video is a detailed masterclass on the new AOT engine. It starts by examining the everyday usecases of an application developer and delves deeper and deeper into the engine, treating concerns that library and framework developers will care about.

Enjoy!

Also, Happy thanksgiving…

Hi, Spring fans! It's Tuesday, the 22nd of November, 2022, as I write this, which means we're two days away from Spring Boot 3 and Thanksgiving. Spring Boot 3, I've written about in abundance so I won't rehash that. If you want to learn more about some of the amazing new features in Spring Framework 6 and Spring Boot 3, perhaps check out my Spring Tips installment introducing them in this episode:

And, of course, a major new feature in Spring Boot 3 is the new ahead-of-time (AOT) engine, about which I speak at great length in tomorrow's new installment of Spring Tips:

This video is done so…

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to Java Champion, legendary engineer, and teacher Trisha Gee (@trisha_gee) bout her extraordinary career working at organizations like LMAX, MongoDB, Jetbrains, and her new books, Heads First Java, and Getting to Know IntelliJ IDEA.

Hi, Spring fans! How're you doin' this fine Tuesday morning? I've returned home to San Francisco and am up and at 'em nice and early to catch a flight to Seattle, where I'll speak at the Java User Group tonight. If you're in Seattle, don't miss it!

We've got a ton of cool stuff to get into this week, but let's not bury the lede here: Spring Framework 6 comes out tomorrow, Wednesday, the 16th of November, 2022! And you know where to go to get the bits: the Spring Initialzr, start.spring.io!

This blog gives an update on the Schema Registry support that is part of Spring Cloud Stream version 4.0.x.

Many enterprises use a schema registry for schema evolution use cases, such as the Confluent Schema Registry. Starting with version 1.1.x of Spring Cloud Stream until 3.0.0, we provided a schema registry server and AVRO-based schema registry client converters that can reconcile the schema from the schema registry server. Spring Cloud Stream version 3.0.0 moved the Schema Registry components into a top-level spring-cloud project, and Spring Cloud Stream included those in its BOM for the…
