I am working on the Spring WebFlux project.
I set values like below in my RestAuthFilter file.

exchange.getAttributes().put(UserConstants.ROLE, claims.get(UserConstants.ROLE));

Here the value is set and I could read it.

But When I am trying to get the same in the Controller file like below the value is NULL

String accessRole = exchange.getAttribute(UserConstants.ROLE);

Anyone can explain and give the solution, please?
