How to use @ControllerAdvice for ViewController's (registered using ViewControllerRegistry)

Question

For having a global @ModelAttribute, I am using a @ControllerAdvice, like this:

@ControllerAdvice
public class MyControllerAdvice {

    @ModelAttribute("globalModelAttribute")
    public String getFacebookScope() {
        return "FACEBOOK_SCOPE";
    }

} 

Now I am able to access the globalModelAttribute in all my JSPs except those which are registered as ViewControllers, like this:

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("home");
        registry.addViewController("/login").setViewName("login");
    }

}

Liked to know how to go about this.

Answer 1

Seems that you cannot use addViewControllers("/login") because it bypass the @ControllerAdvice.

Fixed by creating a @RequestMapping for "/login".
