1.刪除ActionForm
2.struts-config.xml加入plug-in，從blank copy，注意看value有兩個xml：validator-rules.xml(通常不需修改，包在jar檔內)和validation.xml struts-core-1.3.10.jar下的org.apache.struts.validator有validator-rules.xml
3.copy validateion.xml，還是從blank copy，copy到1的value的地方
4.struts-config.xml修改如下：
<form-beans> <!--type改成框架路徑--> <form-bean name="ooo" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="username" type="java.lang.String" /> <form-property name="password" type="java.lang.String" /> </form-bean> </form-beans>
Action修改如下
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
DynaValidatorForm dvf = (DynaValidatorForm) form;
String username = (String) dvf.get("username");
String password = (String) dvf.get("password");
// action想存錯誤訊息可用這兩行
ActionErrors errors = new ActionErrors();
request.setAttribute(Globals.ERROR_KEY, errors);
if (username.trim().equals("aaa") && password.trim().equals("111")) {
return mapping.findForward("success");
} else {
errors.add("user", new ActionMessage("actionUP"));
return mapping.findForward("fail");
}
}
vadation.xml設定如下：
官方文件：struts-1.3.10/docs/faqs/validator.html
．depends可以打很多，用逗號隔開，要參考validator-rules.xml
．validator-rules.xml的required有msg="errors.required"，用搜尋可得key=value，
把它整段復製到自己的properties
．name為depends裡的其中一項，key是properties的key，給{0}用的
．msg是自訂訊息； arg是用validator-rules.xml的訊息
<form name="ooo"> <field property="username" depends="required"> <!-- <arg key="vusername" name="required" position="0" /> --> <msg name="required" key="username"/> </field> <field property="password" depends="required"> <arg key="vpassword" name="required" position="0" /> </field> </form>
properties
username=username can't empty
password=password can't empty
actionUP=please Enter legal username and password!
errors.required={0} is required.
vusername=\u5E33\u865F
vpassword=\u5BC6\u78BC
index.jsp的property要改成和validation.xml的property一樣
<html:errors/> <form action="<c:url value="/xxx.do"/>"> 帳：<input type="text" name="username" /><html:errors property="username" /><br /> 密：<input type="password" name="password" /><html:errors property="password" /><br /> <input type="submit" value="送出" /> <input type="reset" value="重置" /> </form>
其他檔案都和Struts(一)裡的一樣
※多個驗證可修改如下，如密碼是必填也必須是數字：
<form name="ooo"> <field property="username" depends="required"> <!-- <arg key="vusername" name="required" position="0" /> --> <msg name="required" key="username"/> </field> <field property="password" depends="required, integer"> <arg key="vpassword" name="required" position="0" /> <arg key="vpassword" name="integer" position="0" /> </field> </form>properties也要多增加一行，從validator-rules.xml copy
username=username can't empty
password=password can't empty
actionUP=please Enter legal username and password!
errors.required={0} is required.
vusername=\u5E33\u865F
vpassword=\u5BC6\u78BC
errors.integer={0} must be an integer.
depends加多個用逗點隔開即可，但arg的name加多個也是可以run，但key就會變成null
※date型態和範圍稍為難一點，我新增兩個欄位如下：
index.jsp<form action="<c:url value="/xxx.do"/>"> 帳：<input type="text" name="username" /> <html:errors property="username" /><br /> 密：<input type="password" name="password" /> <html:errors property="password" /><br /> 範圍：<input type="text" name="intRangeTest" /> <html:errors property="intRangeTest" /><br /> 日期：<input type="text" name="dateTest" /> <html:errors property="dateTest" /><br /> <input type="submit" value="送出" /> <input type="reset" value="重置" /> </form>
struts-config.xml也要增加，注意日期的type是String，我用java.util.Date會報錯
<form-bean name="ooo" type="org.apache.struts.validator.DynaValidatorForm"> <form-property name="username" type="java.lang.String" /> <form-property name="password" type="java.lang.String" /> <form-property name="intRangeTest" type="java.lang.String" /> <form-property name="dateTest" type="java.lang.String" /> </form-bean>
validation.xml範圍我設定100~2000，日期驗證官方說是用SimpleDateFormat：
<form name="ooo">
<field property="username" depends="required">
<!-- <arg key="vusername" name="required" position="0" /> -->
<msg name="required" key="username"/>
</field>
<field property="password" depends="required, integer">
<arg key="vpassword" name="required" position="0" />
<arg key="vpassword" name="integer" position="0" />
</field>
<field property="intRangeTest" depends="intRange">
<arg position="0" key="vintRangeTest"/>
<arg position="1" name="intRange" key="${var:min}" resource="false"/>
<arg position="2" name="intRange" key="${var:max}" resource="false"/>
<var>
<var-name>min</var-name>
<var-value>100</var-value>
</var>
<var>
<var-name>max</var-name>
<var-value>2000</var-value>
</var>
</field>
<field property="dateTest" depends="date, required">
<arg position="0" key="vdate" name="date"/>
<var>
<var-name>datePattern</var-name>
<var-value>yyyyMMdd</var-value>
</var>
<arg key="vdate" name="required" position="0" />
</field>
</form>
properties：
username=username can't empty
password=password can't empty
actionUP=please Enter legal username and password!
errors.required={0} is required.
vusername=\u5E33\u865F
vpassword=\u5BC6\u78BC
errors.integer={0} must be an integer.
vintRangeTest=\u7BC4\u570D
errors.range={0} is not in the range {1} through {2}.
errors.date={0} is not a date.
vdate=\u65E5\u671F
※validwhen
當所有的驗證都不合乎需求時，那只好自己寫了將jsp，struts-config都恢復成帳號和密碼兩個欄位
properties，validwhen需要用errors.required，但訊息不是我們要的，先改一下
username=username can't empty
password=password can't empty
actionUP=please Enter legal username and password!
errors.required={0} \u9A57\u8B49\u5931\u6557
vusername=\u5E33\u865F
vpassword=\u5BC6\u78BC
errors.integer={0} must be an integer.
validation.xml，<var-value>裡面的語言自成一格，
*this*：為自己的欄位； 要抓其他欄位只要寫property裡的名字即可
寫完一定要用()包起來，否則會出「SYSTEM ERROR: Check logs for details.」的錯
<field property="username" depends="required"> <msg name="required" key="username"/> </field> <field property="password" depends="integer, validwhen"> <arg key="vpassword" name="integer" position="0" /> <arg key="vpassword" name="validwhen" position="0" /> <var> <var-name>test</var-name> <var-value>((*this* == '111') and (username == "aaa"))</var-value> </var> </field>
※客戶端驗證
之前的全都是伺服器端的驗證，Struts也支緩客戶端驗證。 其實就是把剛剛的錯誤訊息變成alert出來
1.<html>裡加屬性 formName
2.<form>增加name和onsubmit屬性
3.我試的結果只有required (必填)有效
