Spring / Spring7 basics Interview questions
What is Spring Framework 7?
Spring Framework 7 is the current major generation of the Spring Framework, reaching general availability on November 13, 2025 alongside Spring Boot 4. It keeps Java 17 as its minimum baseline while fully supporting Java 25, the latest LTS release, so teams can use records, sealed classes, and pattern matching without being forced onto a new JDK immediately.
On the server side, it aligns with Jakarta EE 11 (Servlet 6.1, WebSocket 2.2, Bean Validation 3.1, JPA 3.2), which means deployment now targets Tomcat 11+ or Jetty 12.1+. New capabilities include built-in API versioning, JSpecify-based null safety, a programmatic BeanRegistrar contract, and stronger AOT/GraalVM native image support.
