struts validator验证框架

struts validator验证框架

1、配置：
* 加入国际化配置在struts-config.xml文件中，如：
  <message-resources parameter="MessageResources" />
* 提供国际化资源文件
* 引入validator插件在struts-config.xml文件中，如：
  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
    <set-property
        property="pathnames"
        value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
    </plug-in>
  * 提供validation.xml和validator_rules.xml文件，将此文件拷贝到WEB-INF下

2、validator服务器端验证
* 配置validation.xml文件

3、validator客户端验证(javascript)
) * 配置validation.xml文件
* 在jsp页面中包含< html:javascript>
* 对需要验证的表单定义onsubmit事件,其中事件名称为validate+ActionForm的名称，如：validateLoginForm
LoginAction.java

package com.bjsxt.struts;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;

public class LoginAction extends Action {

    public ActionForward execute(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response)
            throws Exception {
		DynaValidatorForm loginForm = (DynaValidatorForm)form;
		String username = (String)loginForm.get("username");
		String password = (String)loginForm.get("password");
		
		return mapping.findForward("success");
	}

}

MessageResources.properties

引用

prompt.username=User Name
prompt.password=User Password

errors.required={0},is required.

MessageResources_zh_CN.properties

引用

prompt.username=\u7528\u6237\u540d\u79f0
prompt.password=\u767b\u5f55\u5bc6\u7801

errors.required={0},\u662f\u5fc5\u987b\u7684.

   This file contains the default Struts Validator pluggable validator
   definitions.  It should be placed somewhere under /WEB-INF and
   referenced in the struts-config.xml under the plug-in element
   for the ValidatorPlugIn.

      <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,
                                                  /WEB-INF/validation.xml"/>
      </plug-in>

   These are the default error messages associated with
   each validator defined in this file.  They should be
   added to your projects ApplicationResources.properties
   file or you can associate new ones by modifying the
   pluggable validators msg attributes in this file.

   # Struts Validator Error Messages
   errors.required={0} is required.
   errors.minlength={0} can not be less than {1} characters.
   errors.maxlength={0} can not be greater than {1} characters.
   errors.invalid={0} is invalid.

   errors.byte={0} must be a byte.
   errors.short={0} must be a short.
   errors.integer={0} must be an integer.
   errors.long={0} must be a long.
   errors.float={0} must be a float.
   errors.double={0} must be a double.

   errors.date={0} is not a date.
   errors.range={0} is not in the range {1} through {2}.
   errors.creditcard={0} is an invalid credit card number.
   errors.email={0} is an invalid e-mail address.

   Note: Starting in Struts 1.2.0 the default javascript definitions have
         been consolidated to commons-validator. The default can be overridden
         by supplying a <javascript> element with a CDATA section, just as
         in struts 1.1.
