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.

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.
