Multiple WebSecurityConfigurerAdapter in spring boot for multiple patterns

Question

I am trying to set up multiple WebsecurityConfigurerAdapter for my project where the spring boot actuator APIs are secured using basic auth and all other endpoints are authenticated using JWtAuthentication. I am just not able to make it work together, only the config with the lower order works. I am using Spring Boot 2.1.5.RELEASE

Security Config One with JWT Authenticator

@Order(1)
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    private static final String[] AUTH_WHITELIST = {
        "/docs/**",
        "/csrf/**",
        "/webjars/**",
        "/**swagger**/**",
        "/swagger-resources",
        "/swagger-resources/**",
        "/v2/api-docs"
    };

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers(AUTH_WHITELIST).permitAll()
            .antMatchers("/abc/**", "/abc/pdf/**").hasAuthority("ABC")
            .antMatchers("/ddd/**").hasAuthority("DDD")
            .and()
            .csrf().disable()
            .oauth2ResourceServer().jwt().jwtAuthenticationConverter(new GrantedAuthoritiesExtractor());
   }
}

The basic Auth config with username/password

@Order(2)
@Configuration
public class ActuatorSecurityConfig extends WebSecurityConfigurerAdapter {

/*    @Bean
public UserDetailsService userDetailsService(final PasswordEncoder encoder) {
    final InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
    manager.createUser(
            User
                    .withUsername("user1")
                    .password(encoder.encode("password"))
                    .roles("ADMIN")
                    .build()
    );
    return manager;
}

@Bean PasswordEncoder encoder(){
    return new BCryptPasswordEncoder();
}*/

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
            .antMatchers("/actuator/**").hasRole("ADMIN")
            .and()
            .httpBasic();
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication().withUser("user1").password("password").authorities("ADMIN");
  }
}

I have been trying to make it work for many days but cannot make both of them work together. If i swap the order, only basic auth works and not the JWT Auth Manager.

I have gone through a lot of SOF Questions, like

Nothing seems to be working, is this a known issue in Spring?

To use multiple WebsecurityConfigurerAdapter, you need restrict them to specific URL patterns using RequestMatcher.

In your case you can set a higher priority for ActuatorSecurityConfig and limit it only to actuator endpoints:

@Order(-1)
@Configuration
public class ActuatorSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .requestMatchers().antMatchers("/actuator/**")
                .and()
                .authorizeRequests().anyRequest().hasRole("ADMIN")
                .and()
                .httpBasic();
    }
}
