Using spring security annotations with keycloak

I'm just a beginner in Spring Security, but I would like to know is it possible to configure keycloak in a way that I can use @PreAuthorize, @PostAuthorize, @Secured and other annotations. For example, I've configured the keycloak-spring-security-adapter and Spring Security in my simple Spring Rest webapp so that I have access to Principal object in my controller, like this:

@RestController
public class TMSRestController {

     @RequestMapping("/greeting")
     public Greeting greeting(Principal principal, @RequestParam(value="name") String name) {
        return new Greeting(String.format(template, name));
     }
...
}

But when I try this (just an example, actually I want to execute custom EL expression before authorization):

@RestController
public class TMSRestController {

    @RequestMapping("/greeting")
    @PreAuthorize("hasRole('ADMIN')")
    public Greeting greeting(Principal principal, @RequestParam(value="name") String name) {
        return new Greeting(String.format(template, name));
    }
...
}

I get exception:

org.springframework.security.authentication.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext

In my spring security config I enabled global method security:

What do I need to make this spring security annotations work? Is it possible to use this annotation in this context at all?

You still have to configure Spring Security using Keycloak. Take a look at the adapter documentation for an annotation based configuration. Once that's set up your Spring Security annotations will work on authorized calls.
