Upgrading to Spring Framework 6.x

This page provides guidance on upgrading to Spring Framework 6.0.

Upgrading to Version 6.0

Web Applications

Spring MVC and Spring WebFlux no longer detect controllers based solely on a type-level @RequestMapping annotation. That means interfaced based AOP proxying for web controllers may no longer work. Please, enable class based proxying for such controllers or otherwise the interface must also have @Controller. See 22154.
