Hi, Spring fans! Welcome to another installment of This Month in Spring! And what a month it's been! First things first: have you installed the just-released Java 22 yet? No? Well, get on it! It's out there and it's awesome! Java 22 brings with it Project Panama, more contemporaneously known as the foreign function interface. It's awesome! I look at it and a ton of the other new features in this blog, Hello, Java 22!
Second, I did a really long blog looking at building modern Spring applications in early 2024, check that out!
This last month has been nutty! I just had a lovely bit of PTO in Miami, Florida, where I got to see my ol' friend Jon Schneider, lead of OpenRewrite, a powerful tool for refactoring and migrating Java applications. And now, I'm in Bucharest, Romania, where I'll be keynoting the epic VOXXED DAYS Bucharest event here in a few short days. It's going to epic. Or, at least I hope so. Also, I'll be keynoting the Microsoft JDConf later this week. And, I'll be keynoting Google Cloud Next in early April! Don't miss any and all of these events! It'll be fun.
And, of course, the community has been as busy as ever in the last month since we spoke and there's a ton to get into, so let's delay not one second more, and let's dive right into it!
This is interesting, and a nice application of AI (do I even need to spell out "artificial intelligence" anymore?): localize applications with Spring AI
James Ward, founder of the WebJars project and a legend in his own right, invites folks to contribute feedback on the new webjars-locator-lite module, created by the good, the great, the amazing and inimitable Dr. David Syer
the Webjars project needs your help! Try out this new Webjars locator implementation, contributed by our very own Dr. Syer, to make webjars even more performant when used in the context of something like a Spring Boot application.
A propos: if you're running Java 8 onward on macOS 14.4 on Apple Silicon, then you may be susceptible to a regression in macOS that'll manifest as apparent and sudden quit outs of your Java process. There is no fix yet, so Oracle advise considering delaying your upgrade.
I was captivated by this blog that I invited Paul and his colleague Kavitha Srinivasan to join me for a good discussion and demo on not just the garbage collector usage, but their migration to Spring Boot, their use of Java 21, some of the things they're doing to improve startup time, and of course the amazing synergistic work they're doing, with us, to make Spring GraphQL and Netflix's DGS frameworks play well together.
In last week's episode of Spring Tips, I continued our series introducing the Spring Authorization Server, this time applying it to support and secure single-page applications and messaging flows. Stay tuned for the last installment, landing tomorrow – Wednesday, the 6th of March, 2024!
This is an old curio I just discovered that has zero future, but I think is kind of interesting nonetheless: would you like to use the Java HTTP Server (the one included in the JDK) as a Spring Boot WebServer? This old codebase from around 2019 shows how. It, alas, does not work well if you update it because there's been an en masse migration from Java EE to Jakarta EE since then that breaks a lot of the code.
Want to rotate SSL certificates with Spring Boot on a Kubernetes platform like OpenShift? Check out this blog.
I had a nice discussion with some of the folks working on Microcks, a consumer driven testing option that works well with Spring. This new release features improved Testcontainers support and GraalVM native image test support.
Exciting to see GraalVM native image support landing in the Azure OpenAI SDK module for Java
