Struts-数据校验

Struts数据校验方式：

ActionForm

Action

commons-validator.jar

1.ActionForm

-- 重写ActionForm.validate ，错误封装在ActionError

LoginForm extends ActionForm implements Serializable{

public ActionErrors validate(ActionMapping mapping,HttpServletRequest req){

ActionErrors ae --- 不推荐使用

ae.add("id",new ActionError("",""))

}

}

<bean:message key="button.reset"/>

<html:errors />

2.Action

request.setAttribute("errors","");

request.findForward("");

3.commons-validator.jar

1.LoginForm extends ValidatorForm

2.validator-rules.xml , validatation.xml -> WEB-INF

validatation.xml 项目校验文件

<form-validation>

<formset>

<form name="loginForm">

<field property="" depends="">
