Any Spring conditional annotation whose condition depends on the value of a specific variable?

I'm new to Spring and have started building Web services with Springboot. There is a requirement that says I have to enable / disable a RestController based on a value of a specific variable of a Class.

I was looking at all the questions here dealing with @ConditionalOnExpression and @ConditionalOnProperty, but none of them told me if I could set the condition of a RestController on the basis of a value of a variable.

If I have the following class 

public class CheckCondition {

  public boolean allowed = true;
}

what conditional annotation should I use to that will decide the condition on the basis of the class's variable's value?

you can write your own conditional class by extending Condition interface. Something like this 

class SomeCondition implements Condition {
    @Override
    public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {

       //do your logic and return true or false based on some condition
    }
}

And then you can use this condition on a class like this 

@Configuration
@Conditional(value = SomeCondition.class)
public class YourClass{
}
