Spring WEBFLUX : RouterFunctionWebHandle cannot be easily extended/overwritten; embedded in RouterFunctions

Want to read in external properties from a JSON schema for routerFunctionWebHandle but this cannot be easily extended/overwritten without entire routerfunctions class needing overwritten.

Suggest abstracting these out.

Please take the time to describe the use case if you want us to consider a change. Since you seem to have tried something already, sharing a small sample that represents that is the next logical step for us to review. Thanks.

I am wanting to upload external API RULES from a JSON schema to not only set ROUTING but to also set RBAC/ABAC settings (ie ROLES) for the endpoints.

The ROUTING can be dne with ROUTERFUNCTIONS (I know this) BUT... applying ROLES dynamically as well as the expected request params/response params associated with each ROLE per endpoint requires access to something similar to a 'RequestHandler'

And from my understanding, all these are inner classes, have been made PRIVATE and are combined into one class.

This makes it impossible to extend.

Does this help??

These types are internal by design, and supposed to be extended. Instead, they are designed to be composed on.

The main reason for this is backward compatibility: having private types allows us much more flexibility, whereas public types would need to be backward compatible to a far higher degree.
