持久层hibernate技术使用的一个例子

package cn.hope.front.form.validation;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.validator.Field;
import org.apache.commons.validator.ValidatorAction;
import org.apache.commons.validator.util.ValidatorUtils;
import org.apache.struts.action.ActionMessages;
import org.apache.struts.validator.Resources;
public class U05FrontFormValid {
	public static boolean idCardValidate(Object bean, ValidatorAction va, Field field,
			ActionMessages errors, HttpServletRequest request) {
		try {
			String idcard = ValidatorUtils.getValueAsString(bean, field
					.getProperty());

			if(idcard.length()!=18 && idcard.length()!=15){
				errors.add(field.getKey(), Resources.getActionMessage(request, va,
						field));
				return false;
			}
		} catch (Exception e) {
			e.printStackTrace();
			return false;
