Spring-security: Spring WebFlux doesn't mix when Jackson mixins are applied

[gregturn]

Origin: https://github.com/spring-projects/spring-session-data-mongodb/issues/33

Problem: Spring WebFlux + Spring Security + Spring Session MongoDB + JacksonMongoSessionConverter.

WebJackson2Module registers multiple mixins including CookieMixin. This fails because Cookie is not on the classpath.

Possible solution: Conditionalize some of these registrations so they are only done when Spring MVC on the classpath.

    public void setupModule(SetupContext context) {
        SecurityJackson2Modules.enableDefaultTyping((ObjectMapper)context.getOwner());
        context.setMixInAnnotations(Cookie.class, CookieMixin.class);
        context.setMixInAnnotations(SavedCookie.class, SavedCookieMixin.class);
        context.setMixInAnnotations(DefaultCsrfToken.class, DefaultCsrfTokenMixin.class);
        context.setMixInAnnotations(DefaultSavedRequest.class, DefaultSavedRequestMixin.class);
        context.setMixInAnnotations(WebAuthenticationDetails.class, WebAuthenticationDetailsMixin.class);
        context.setMixInAnnotations(PreAuthenticatedAuthenticationToken.class, PreAuthenticatedAuthenticationTokenMixin.class);
    }
