Answer 1

Use a custom authentication provider.

or implement AuthenticationProvider class and write your authentication logic.

and after that

@Configuration
public class YourWebSecurityConfiguration extends WebSecurityConfigurerAdapter{

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.authenticationProvider(yourAuthProviderBean);

  }
}
