Answer 1

As per spring-oauth2 docs https://projects.spring.io/spring-security-oauth/docs/oauth2.html

Note: if your Authorization Server is also a Resource Server then there is another security filter chain with lower priority controlling the API resources. Fo those requests to be protected by access tokens you need their paths not to be matched by the ones in the main user-facing filter chain, so be sure to include a request matcher that picks out only non-API resources in the WebSecurityConfigurer above.

So define WebSecurityConfigurer implementation with higher order than ResourceServerConfig.
