http
        .csrf(AbstractHttpConfigurer::disable)
        .cors(AbstractHttpConfigurer::disable)
        .addFilterAfter(CoustomAuthCheckFilter, UsernamePasswordAuthenticationFilter.class)
...

I used AuthenticationFilter.class in the addFilterAfter method and encountered an error. After changing it to UsernamePasswordAuthenticationFilter.class, it worked. Why does the compiler not throw an error when using AuthenticationFilter.class even though it’s not a concrete filter that is typically used directly?”

try

http
        .csrf(AbstractHttpConfigurer::disable)
        .cors(AbstractHttpConfigurer::disable)
        .addFilterAfter(CoustomAuthCheckFilter, AuthenticationFilter.class)

I expecting server start. but
