Миграция на Spring Boot 4 и Java 25: пошаговый план, чтобы обновиться и не уронить прод

Мажорное обновление редко ломает сервис сразу и красиво. Чаще оно оставляет тихую регрессию в сериализации, безопасности, тестах или рантайме — и всплывает уже после релиза. В этой статье разбираем, как перейти со Spring Boot 3.x на 4.0 и с Java 21 на Java 25 не одним рискованным прыжком, а как управляемой инженерной процедурой: с промежуточной остановкой, проверками, канарейкой и понятным планом отката. Разобрать миграцию

Spring AI 2.0 is now available 🚀 it supports both Spring Boot 4.0 and 4.1. I worked on automated OpenRewrite recipes to upgrade your applications to the new version, taking care of many breaking changes introduced in this new major. All free and open source.

I'm constantly improving them, so feel free to share your experience if you try them out, so that we can make them even better. Thanks!

Spring Boot 4.1 has been released yesterday 🚀 and Spring Boot 3.5 has received its final patch. From this month, it's officially out of OSS support. I've implemented OpenRewrite recipes to automate most of the migration process. All free and open source.

Modernizing #Java at scale fails when refactoring isn’t repeatable. Bryan Friedman shows how #OpenRewrite enables safe, deterministic upgrades across massive codebases.

AI can write Java code—but can it safely modernize hundreds of legacy systems? Bryan Friedman explains why enterprise #Java needs deterministic refactoring, not probabilistic #AI guesses.

@campfireman The only tool I know of that plays the same role is #OpenRewrite https://docs.openrewrite.org/

@OpenRewrite

I was asked after the "Refactoring to #EclipseCollections" talk at dev2next 2025 whether there were any #OpenRewrite recipes for EC. My answer was "No, but it would be great if someone contributed some in OSS." Thanks Craig Motlin! 🙏 @zakhav @jitterted

I enjoyed yesterday’s chat at Code Remix Weekly by Moderne. We talked about Arconia, how it enhances the developer experience for Java and Spring Boot apps, and the key role of OpenRewrite for maintaining and growing the project. https://www.youtube.com/watch?v=v_KpRj9UXls

Stuck on old #Java versions? You’re not alone. @MBoegie shows how to overcome legacy fear, cut tech debt, & modernize with tools like #OpenRewrite — turning migrations from pain into progress.

#OpenRewrite is really neat. I used it to do some really impressive conversions. I haven't had this much fun since Jackpot refactoring in #Netbeans. I do wish it had better error messages rather than dozens of 800 line stack traces. Expect to see some contributed conversions soon…

Our next event will take place on Thrusday, October 30th at our host, Intact Lab.

This event will be in english 🇬🇧 (french comments / questions welcome 🇫🇷!).
