struts2中报“ Could not find action or result”

背景：struts2中对从表单输入的内容进行校检，要求错误信息在原页面（表单页面）显示时，会将错误信息默认转发到名为input的result

错误如下：警告: Could not find action or result

No result defined for action cn.itcast.Action.PersonAction and result input

错误根源：<package name="person" namespace="/person" extends="struts-default">

<action name="manage_*" class="cn.itcast.Action.PersonAction" method="{1}">

<result name="message">/WEB-INF/page/message.jsp</result>

</action>

</package>

缺少了一句(加在action中)：

<result name="input">/index.jsp</result>

正确写法：

<package name="person" namespace="/person" extends="struts-default">

<action name="manage_*" class="cn.itcast.Action.PersonAction" method="{1}">

<result name="input">/index.jsp</result>

<result name="message">/WEB-INF/page/message.jsp</result>

</action>

</package>
