How to use annotations for security constraints in Spring Boot REST controller classes?

Getting advice

Hello everyone,

I just started using Keycloak in combination with Spring Boot. Is there a way that I can use annotations in REST controller classes instead of the application.yml configuration for “security-constraints”? What do I have to configure in my Spring Boot application for this or is this not a good idea?

application.yml

keycloak:
    [...]
    security-constraints:
        - authRoles:
            - admin
        securityCollections:
            - patterns:
                - /

Versus something like:

GreetingExampleController.java

@RestController
public class GreetingExampleController extends BaseController {

    @NecessaryRoles({
      "admin"
    })
    @GetMapping("hello-world")
    public String greeting() {
        return "Hello World!";
    }
}

Thank you in advance.
