Been self learning Spring Security for a while, and I am now kind of stuck in filter chain. Let's say I have a StaticKeyAuthenticationFilter class, marked with @Component, implements Filter, and has @Value("${authorization.key}"), so that it can read the key value from the yml file.

@Component
public class StaticKeyAuthenticationFilter implements Filter {

    @Value("${authorization.key}")
    private String authorizationKey;

    private final Logger logger = Logger.getLogger(StaticKeyAuthenticationFilter.class.getName());


    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

        HttpServletRequest httpRequest = (HttpServletRequest) servletRequest;
        HttpServletResponse httpResponse = (HttpServletResponse) servletResponse;

        String cAuthentication = httpRequest.getHeader("Cauthorization");

        if(authorizationKey.equals(cAuthentication)) {
            filterChain.doFilter(httpRequest, httpResponse);
        }
        else {
            logger.info("No cAuthentication in request's header...");
            httpResponse.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        }
    }
}

And in the SecurityFilterChain class:

@Configuration
@EnableWebSecurity(debug = true)
public class SecurityConfig {
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http.httpBasic(Customizer.withDefaults());
        return http.build();
    }
}

Clearly I am not including the StaticKeyAuthenticationFilter, but from what I see in the log, it's still somehow registered in the filterchain:

2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : helloController
2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : staticKeyAuthenticationFilter
2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : customerService
2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : com.example.Book_Store_Blog.BookStoreBlogApplication$FindAllCustomer
2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : passwordEncoder
2025-01-30T14:17:41.042+08:00  INFO 18884 --- [Book_Store_Blog] [           main] c.e.B.BookStoreBlogApplication           : authenticationProvider

My assumption would be that it's always in the filter chain because it's marked @Component (I think I need the @Component, otherwise the @Value("${authorization.key}") won't work)

How can I dynamically exclude the StaticKeyAuthenticationFilter from the filter chain instead of commenting out the logic inside the filter?

All I can think of is to remove the @Component annotation or comment out the logic inside of the filter, but it's not dynamic.

I also tried FilterRegistrationBean, but when I say staticKeyAuthenticationBean().setEnabled(false), it always gives me the 'fails to construct StaticKeyAuthenticationFilter bean' error.
