Java 17 и Jakarta EE 9 — минимальные требования для Spring Framework 6 От переводчика: на конференции SpringOne были сделаны довольно важные анонсы относительно нового поколения Spring Framework, на Хабре это почему-то это прошло незамеченным. Судя по всему, в ближайшее время мы будем жить не просто в мире “Java 8/Java 11+”, а появится ещё один водораздел: “Spring 5/Spring 6+”. Чем это грозит?

Внешние данные конфигурации в Spring Большинство наших приложений зависят от внешних сервисов, например серверов баз данных, SMS-шлюзов и систем наподобие PayPal. Эти сервисы могут существовать более чем в одной среде, то есть в средах разработки и эксплуатации.
