Descrizione

Is your feature request related to a problem? Please describe. I have a specfic kind of caching logic that should not use the header values. In the current implementation of the CacheKeyGenerator there is a static list of key generators that I cannot modify.

Describe the solution you'd like Add an api or spring mechanism to change the key generator.

Describe alternatives you've considered I tried to modify that static field at runtime but this approach is really hacky.

Additional context I have not used spring for a long time. Maybe there is already a way to change the CacheKeyGenerator or ResponseCache implementation.

Direzione di ricerca
Investigate the current implementation of CacheKeyGenerator in ResponseCacheGatewayFilter, which uses a static list of key generators. Explore ways to allow users to customize the key generator, such as introducing a Spring bean or a configuration property. Look at the source code in spring cloud gateway's filter package, specifically the ResponseCacheGatewayFilter and CacheKeyGenerator classes. Consider if a strategy pattern or an extension point via Spring's ApplicationContext can be used.
