For the latest stable version, please use Spring Framework 6.2.0!

HTTP/2

See equivalent in the Reactive stack

Servlet 4 containers are required to support HTTP/2, and Spring Framework 5 is compatible with Servlet API 4. From a programming model perspective, there is nothing specific that applications need to do. However, there are considerations related to server configuration. For more details, see the HTTP/2 wiki page.

The Servlet API does expose one construct related to HTTP/2. You can use the jakarta.servlet.http.PushBuilder to proactively push resources to clients, and it is supported as a method argument to @RequestMapping methods.
