Hi Spring fans! Welcome to another installment of This Month in Spring! It's shaping up to be quite the month indeed. I just returned from the epic SpringOne Tour event in Columbus, Ohio, and now I'm on a jet winging my way to Tel Aviv, Israel. I'll be speaking at the local Java User Group and speaking to some customers while I'm there. Then, I've got some live training events that you can still sign up for on Safari: the first is on using Kotlin with Spring and the second is on Testing with Spring. Then, it's off to Atlanta, Georgia, for the seminal DevNexus conference where I'll have the honor of presenting with the good Dr. Venkat Subramaniam on all things Kotlin (don't miss this!). Then, it's off to Seattle for the Seattle Java User Group. Then, it's off to beautiful Montreal, Canada for the amazing Confoo show where I'll be talking about testing Spring applications. Then, it's off to the SpringOne Tour London event and the SpringOne Tour Amsterdam stops. I've got a few customer visits after that and then it's off to the Kafka Summit in New York City where I'll be speaking with the legendary Tim Berglund on all things Kafka and streaming with Kafka and Spring. I'd love to see you there for all of those events! Sign up, subscribe, set a reminder, book a flight, and of course don't hesitate to say on Twitter one way or another.
I've got a new podcast and I'm trying to make it amazing. Have you given it a listen already? It's called A Bootiful Podcast. You can find links to the podcast for Apple and Google devices, as well as the Patreon page where you could optionally help support the production costs associated with making the podcast, here.
This last week saw the conclusion of season 5 of Spring Tips and the publication of a season 5 recap. I'm already hard at work on season 6, of course, so stay tuned. If you get through the season 5 episodes, then you might go back and watch the older ones.
The Spring team have been fast at work on tons of stuff, of course, and in particular we're working on Spring Boot 2.2 and there are tons of cool things coming in Spring Boot 2.2. I encourage you to go try the new version at the Spring Initializer. Select 2.2 or later from the dropdown. You might also try running your application with a the
-noverify JVM argument and
-Dspring.main.lazy-initialization=true. I think you'll be very impressed with the performance gains.
