The Spring Framework 7 is here, aligning with Java 25 while preparing for the upcoming Spring Boot 4.0, all while maintaining compatibility with Java 17. Notable updates include API versioning, allowing server-side configuration to resolve, analyze, and validate API versions, with options to mark versions as deprecated for client notifications. Clients can specify API versions in requests and through the HTTP interface.
Improved HTTP client interface configuration is another highlight, simplifying processes when dealing with multiple HTTP interfaces and host targets. The introduction of JmsClient streamlines common JMS operations, serving as a reusable alternative to JmsMessagingTemplate.
Additionally, the new null safety system, JSpecify, replaces the outdated JSR 305 semantics. It empowers developers to declare the nullability of elements, fields, and generic types.
