Java – spring boot oauth2 with custom security filters

I have a spring boot setup with oauth2 authorization and resource server The user can obtain the token by sending a post request to / OAuth / token So far, it's very good@ H_ 404_ 7@

@Configuration
@EnableResourceServer
protected static class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {
    // ...
    @Override
    public void configure(HttpSecurity http) throws Exception {
        // ...
        http.addFilterBefore(new DemoAuthenticationFilter(),BasicAuthenticationFilter.class);
        http.authorizeRequests().antMatchers("/oauth/token").authenticated();
    }
}

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    // ...
    @Override
    protected void configure(HttpSecurity http) throws Exception {
       // ...
       http.addFilterBefore(new DemoAuthenticationFilter(),BasicAuthenticationFilter.class);
       http.authorizeRequests().antMatchers("/oauth/token").authenticated();
    }
