Spring security webSecurity.ignoring ()

Question

I use spring security with spring boot. I have two types of leisure services.

public / ** → Everyone can access and use these services

secure / ** → Only authenticated users can be used.

@Slf4j
@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
public void configure(WebSecurity webSecurity) throws Exception {
    webSecurity.ignoring().antMatchers("/public/**");
}

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.addFilterBefore(requestHeaderAuthenticationFilter(authenticationManager()),
            BasicAuthenticationFilter.class)
            .authorizeRequests().antMatchers("/secure/**").fullyAuthenticated();
}

@Bean
public RequestHeaderAuthenticationFilter requestHeaderAuthenticationFilter(
        final AuthenticationManager authenticationManager) {

    RequestHeaderAuthenticationFilter filter = new RequestHeaderAuthenticationFilter();
    filter.setAuthenticationManager(authenticationManager);
    filter.setExceptionIfHeaderMissing(true);
    filter.setPrincipalRequestHeader("MY_HEADER");
    filter.setInvalidateSessionOnPrincipalChange(true);
    filter.setCheckForPrincipalChanges(false);
    filter.setContinueFilterChainOnUnsuccessfulAuthentication(false);
    return filter;
}

When I want to access a resource in the public domain, I got an exception.

exception: "org.springframework.security.web.authentication.preauth.PreAuthenticatedCredentialsNotFoundException"

message: "The header MY_HEADER was not found in the request."

Why is my filter activated under an open resource while it is configured as an ignored resource?

thanks in advance
