You can add a BasicAuthenticationFilter to the security filter chain to get OAuth2 OR Basic authentication security on a protected resource. Example config is below...

@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManagerBean;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        final String[] userEndpoints = {
            "/v1/api/airline"
        };

        final String[] adminEndpoints = {
                "/v1/api/jobs**"
            };

        http
            .requestMatchers()
                .antMatchers(userEndpoints)
                .antMatchers(adminEndpoints)
                .antMatchers("/secure/**")
                .and()
            .authorizeRequests()
                .antMatchers("/secure/**").authenticated()
                .antMatchers(userEndpoints).hasRole("USER")
                .antMatchers(adminEndpoints).hasRole("ADMIN");

        // @formatter:on
        http.addFilterBefore(new BasicAuthenticationFilter(authenticationManagerBean),
                UsernamePasswordAuthenticationFilter.class);
    }

}

I believe that is not possible to have both authentications. You can have basic authentication and oauth2 authentication, but for distinct endpoints. The way as you did, the first configuration will overcome the second, in this case, http basic will be used.
