JwtAuthFilter is applied for all requests even for permitted endpoints
I am having some problems with the new Spring Security configuration. I am using the spring boot version 3.1.4 and the spring security version 6.1.4.
In the config file I define that some pages should be accessible without authentication. After that I add my JwtAuthFilter to the chain. However it is called allways. Even for the endpoints that should be allowed. The error page, which is called for 403 errors is for example allowed to be accessed without authentication. Unfortunately it is also tried to authenticated by the jwtAuthfilter, which leads to another 403 error, which leads to a authentication loop. How can i fix that?
This is my config and my filter.
