struts2问题

Question

这是我的struts的配置文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd" >
<struts>
     <include file="struts-default.xml"/>
     <package name="mail-default" namespace="/" extends="struts-default">
      <interceptors>
      <interceptor name="session" class="com.zytc.mail.interceptor.SessionInterceptor"></interceptor>
       <interceptor name="mailUser" class="com.zytc.mail.interceptor.MailUserInterceptor"></interceptor>

      <interceptor-ref name="mailUser"></interceptor-ref>
      </interceptor-stack>
      </interceptors>
      <default-interceptor-ref name="defaultStack"></default-interceptor-ref>
      <global-results>
<result name="relogin">/index.jsp</result>
</global-results>
     </package>
     <package name="mailUser" extends="mail-default" namespace="/mail">
      <action name="login" class="mailLoginAction">
      <interceptor-ref name="sessionStack"></interceptor-ref>
      <result name="failure">/index.jsp</result>
      <result name="success">/mail/main.jsp</result>
      </action>
      <action name="opt" class="mailOptAction">
      <interceptor-ref name="mailUserStack"></interceptor-ref>
      <result name="sequential">/mail/opt/sequential.jsp</result>
      <result name="listMessages">/mail/opt/listMessages.jsp</result>
      <result name="getAllFolders">/mail/opt/getAllFolders.jsp</result>
      <result name="setAttrs">/mail/opt/setAttrs.jsp</result>
      <result name="compose">/mail/opt/compose.jsp</result>
      <result name="readMessage">/mail/opt/readMessage.jsp</result>
      <result name="searchMessages">/mail/opt/searchMessages.jsp</result>
      <result name="folderInfo">/mail/main/folderInfo.jsp</result>
      <result name="mailContent">/mail/opt/mailContent.jsp</result>
      <result name="fileupload">/mail/opt/upload.jsp</result>
      <result name="createFolder">/mail/opt/createFolder.jsp</result>
      <result name="folders">/mail/opt/folders.jsp</result>
      <!-- 
      <result name="readData">/mail/opt/readdata.jsp</result>
       -->
      <result name="readData" type="stream">
                <param name="inputName">inputStream</param>
                <param name="bufferSize">4096</param>
                <param name="contentDisposition">attachment; filename="${fileName}"</param>
</result>
</action>
     </package>
 </struts>
提交页面有upload控件时就抱这个错误，其他页面没有这个问题，都很正常：
严重: Could not find action or result
No result defined for action com.zytc.web.action.MailOptAction and result input - action - file:/C:/Documents%20and%20Settings/losse.z/workspace/.metadata/.plugins/com.genuitec.eclipse.easie.tomcat.myeclipse/tomcat/webapps/zytcmail/WEB-INF/classes/struts.xml:29:48

感觉是拦截器的upload控件好像是不兼容，求高人解答。

Answer 1

很可能的原因是你在action中有return "xxx"而xxx在配置文件中没有配<result name="xxx"

Answer 2

或者需要配置 <result name="input"你没有配

Answer 3

action里面我已经看过了...return的参数我在配置文件中都配置过了...如果我配置一个<result name="input"的话,,,这个result的页面是接受struts不能处理异常的页面，不能解决问题

Answer 4

先看进到action没有
如果进到那就是result配置的问题了
就是没有找到对应的路径

Answer 5

在你input页面加入<s:fielderror />会显示出错的字段
估计会显示你的那个upload控件有问题
也许是因为upload控件中与action的属性字段类型不一致
在action中那个属性字段的类型应该是java.io.File类型
