Can we Autowired below class into Configuration class in springboot

I have a Component class and a config class,so can we autowire component class which uses @value internally,I tried using it but it throws exception,Can anyone please help me understanding

@Component
public class UserAction {
    @Value("${cp.user.name}")
    private String userName;

    @Value("${cp.user.actiontype}")
    private String actionType;

    @Value("${cp.user.designation}")
    protected Designation designation;

    public void show() {
        System.out.println(userName);
        System.out.println(actionType);
        System.out.println(designation);
    }
} 

@Configuration
@ComponentScan("com.example")
public class AppConfig {

@Autowired
UserAction userAction;
------
}

So My question is : can I autowire my UserAction bean into my AppConfig class? I tried using it but its throwing exception,so can we autowire a component which internally uses @value :

    
Unable to start web server; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'AppConfig ': Unsatisfied dependency expressed through field 'userAction'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userAction': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'cp.user.actiontype' in value "${cp.user.actiontype}"

Yes you can Autowire beans in Configuration class, but the issue here is that a property in your bean has no value set in properties/yml file

@Value("${cp.user.actiontype}")

set the property cp.user.actiontype in your .properties or .yml file
