如何在jsf/Icefaces中跳出时验证正则表达式

<ice:inputText id="myInput" value="#{bean.myValue}">
    <f:validator validatorId="myValidator" />
</ice:inputText>

import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.FacesValidator;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

@FacesValidator("myValidator")
public class MyValidator implements Validator {

    private static final String REGEX_PATTERN = "your-regex-pattern-here";

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        String input = value.toString();
        
        if (!input.matches(REGEX_PATTERN)) {
            FacesMessage message = new FacesMessage("Validation failed. Please enter a valid value.");
            throw new ValidatorException(message);
        }
    }
}

<validator>
    <validator-id>myValidator</validator-id>
    <validator-class>com.example.MyValidator</validator-class>
</validator>
