我尝试使用struts2验证框架。我有一个ActionName-validation.xml。 struts.xml中的条目如下
<action name="registerCandidateStep1" class="candidateAction"
method="registerCandidateStep1">
<result name="success" type="tiles">registerCandidate</result>
<result name="input" type="chain">
<param name="actionName">loadCandidateRegistrationForm</param>
<param name="namespace">/.secureActions</param>
</result>
</action>
<action name="loadCandidateRegistrationForm" class="loadCandidateFromAction"
method="loadCandidateRegistrationForm">
<result name="success" type="tiles">registerCandidate</result>
</action>
错误条件请求转发到“loadCandidateRegistrationForm”但我没有在页面上看到错误。我在jsp中包含了标签
StrutsConfig.xml

主动阻止动作链接,与验证拦截器的交互是其中一个原因。您可以通过将一些值(如验证消息)从一个动作显式映射到下一个动作来绕过它,但是......不要链接动作 - 几乎没有理由这样做。

如Dave
所述,不鼓励使用Action Chaining
。
请勿在家尝试此操作
通常,不建议使用Action Chaining。 首先探索其他选项,例如 Redirect After Post 技术
如果你有充分的理由使用Redirect After Post
,请使用

错误的生命周期持续当前的行动。如果您转发/重定向到其他操作,则错误将会丢失。
请改用session
范围。将ArrayList
放入session
并附加您的错误/消息。
<强>动作/拦截器:强>
Map session = ActionContext.getContext().getSession();
List<String> errors = session.get("errorMessages");
if(errors==null)
session.put("errorMessages", errors=new ArrayList<String>() );
errors.add("Invalid Username/Password. Kindly retry");
<强> JSP:强>
<s:iterator var="msg" value="#session.errorMessages" >
<p> ${msg} </p>
</s:iterator>
<s:set scope="session" var="errorMessages" value="%{null}" /><%--flush errors--%>
