如何为wicket中“required”属性为true的所有组件添加自定义css类？

import org.apache.wicket.Component;
import org.apache.wicket.behavior.Behavior;

public class CustomCssBehavior extends Behavior {
    
    @Override
    public void onConfigure(Component component) {
        super.onConfigure(component);
        
        if (component.isRequired()) {
            component.add(AttributeModifier.append("class", "required-css-class"));
        }
    }
}

TextField<String> textField = new TextField<>("textField");
textField.setRequired(true);
textField.add(new CustomCssBehavior());
