自定制验证器

自定制验证器代码：

package com.itanger.jane.web;

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

public class OneToTenValidator implements Validator {
    public OneToTenValidator() {
    }

    public void validate(FacesContext facesContext, UIComponent uIComponent,
                         Object object) throws ValidatorException {
        boolean Valid = false;
        String value = null;
        int i;
        if (!(uIComponent instanceof UIInput) || (object == null)) {
            return;

        }
        value = object.toString();
        try {
            i = Integer.parseInt(value);
        } catch (NumberFormatException exe) {
            FacesMessage message = new FacesMessage("不能成功的转化");
            throw new ValidatorException(message);
        }
        if ((i < 1) || (i > 10)) {
            FacesMessage message = new FacesMessage("数值应该在1到10之间");
            throw new ValidatorException(message);
        }
        return;
    }

}
