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. Если мы хотим подключиться к эксплуатационной среде, мы должны сначала пройти через среду разработки. Таким образом, во время создания приложений нам приходится переключаться между средами. Это связано с тем, что у каждой среды своя уникальная конфигурация со своими параметрами подключения и прочими значениями.

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? Например, если вы используете Hibernate 5.4, то придется принудительно обновиться на Hibernate 5.5+.
1 сентября на SpringOne было объявлено, что минимальные требования для Spring Framework 6 и Spring Boot 3, который будет доступен в 4 квартале 2022 года, сдвигаются в сторону увеличения:
* Java 17+ (c Java 8-17 в линейке Spring Framework версии 5.3.x)
* Jakarta EE 9+ (с Java EE 7-8 в линейке Spring Framework версии 5.3.x)
