The Spring Social SocialAuthenticationFilter processes the url /auth. How can I change this url?
There is a method SocialAuthenticationFilter.setFilterProcessesUrl(String filterProcessesUrl). How can I access the SocialAuthenticationFilter object to use this method? (I use SpringSocialConfigurer, which automatically adds SocialAuthenticationFilter to the chain.)
Unfortunately using the original SpringSocialConfigurer you can't set the processed url. Looking at the code, you may "only" fluently configure things like postLoginUrl, postFailureUrl, signupUrl, connectionAddedRedirectUrl, defaultFailureUrl and alwaysUsePostLoginUrl.
Imho that's an omission in SpringSocialConfigurer and you may want to file an issue at https://github.com/spring-projects/spring-social/issues.
For the time being, just use the code from SpringSocialConfigurer and come up with your own (small) class.
