Trouble with custom Spring Security filter not executing for specific URL patterns

I'm currently implementing a custom filter in my Spring Boot application using Spring Security, but I'm facing issues where the filter seems to be skipped for specific URL patterns. I've defined my filter to intercept all requests, yet it doesn't trigger for requests to `/api/public/**`. My filter looks like this: ```java @Component public class CustomAuthenticationFilter extends GenericFilterBean { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpServletRequest httpRequest = (HttpServletRequest) request; System.out.println("Intercepted request: " + httpRequest.getRequestURI()); // Custom authentication logic here chain.doFilter(request, response); } } ``` In my security configuration, I have registered this filter after the `UsernamePasswordAuthenticationFilter` like so: ```java @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired private CustomAuthenticationFilter customAuthenticationFilter; @Override protected void configure(HttpSecurity http) throws Exception { http .csrf().disable() .authorizeRequests() .antMatchers("/api/public/**").permitAll() .anyRequest().authenticated() .and() .addFilterAfter(customAuthenticationFilter, UsernamePasswordAuthenticationFilter.class); } } ``` When I make a GET request to `http://localhost:8080/api/public/test`, I don't see the expected output from my filter, but it works fine for other paths like `/api/private/test`. I've tried adjusting the order of the filter and even removed the `permitAll()` configuration to see if that was affecting it, but it seems like the filter is just not executing for public URLs. I also verified that other security settings in the app aren't conflicting. How can I ensure that my custom filter executes for the public endpoints as well?
