@RequestScope is a specialization of @Scope for a component whose lifecycle is bound to the current web request. In spring WebFlux the use of this annotation cause a:
No Scope registered for scope name 'request'
It would be nice have the same feature/annotation in WebFlux to bind the life of a component with the current web request. Currently, I don't think it's possible achieve this behaviour in WebFlux in a simple way (like using an annotation).

Since there is no technical interaction between the core container Scope mechanism and the reactive pipelines in WebFlux controllers, we are not able to provide direct support for @RequestScope. Any such scoped attributes will have to be programmatically added to the reactive pipeline in the controllers instead. If there is anything we can do to make such a programmatic arrangement more convenient, feel free to create a separate issue for it.
