利用struts拦截器，提示No result defined for action com.opensymphony.xwork2.ActionSupport

Question

Struts.xml文件如下    <package name="portal" extends="struts-default">
<interceptors>
<interceptor name="loginfromsap"
class="com.hzj.portal.index.interceptor.LoginFromSapInterceptor" />

<interceptor name="authority"
class="com.hzj.portal.index.interceptor.AuthorityInterceptor" />
<interceptor-stack name="portaldefault">
<interceptor-ref name="basicStack"></interceptor-ref>
<interceptor-ref name="authority">
<param name="excludeMethods">login</param>
</interceptor-ref>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="basicStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="portaldefault"></default-interceptor-ref>
<global-results>
<result name="globalLogin">/fault.jsp</result>
<result name="myError">/myError.jsp</result>
<result name="queryIndex">/WEB-INF/portal/query/queryIndex.jsp</result>
<result name="xqjhSp">/WEB-INF/portal/grad/xqjhSp.jsp</result>
</global-results>


<action name="login_loginfromsap">
          <interceptor-ref name="loginfromsap" /><!-- sap登录用指定的拦截器 -->
        </action>
</package>           
    
url如下http://127.0.0.1:8080/pro/login_loginfromsap.action?forward=xqjhSp类里做了个跳转 try{ String forward = request.getParameter("forward");
if(forward == null) forward="globalLogin";
                           return forward;

}catch(Exception e){
request.setAttribute("exception", e);
        return "myError";
}报的错误信息如下18:36:26,729  WARN Dispatcher:49 - Could not find action or result
No result defined for action com.opensymphony.xwork2.ActionSupport and result xqjhSp

Answer 1

我不知道只是不是问题所在，但是是我的两点疑问：
1.  <action name="login_loginfromsap">
       <interceptor-ref name="loginfromsap" /><!-- sap登录用指定的拦截器 -->
    </action>
    你拦截器不是放在最上面吗，那他一开始就会执行，这里又为什么要在写一便呢，有点浪费，直接写你的<result>不就可以了吗2.18:36:26,729  WARN Dispatcher:49 - Could not find action or result
No result defined for action com.opensymphony.xwork2.ActionSupport and result xqjhSp 是没有找到这个xqjhSp，    而你的<result name="xqjhSp">/WEB-INF/portal/grad/xqjhSp.jsp</result>   在写路径时一般不带WEB-INF吧，他会自己默认找他的，要是在写一个的话，他会以为是WEB-INF下还有个文件夹叫WEB-INF

Answer 3

 Could not find action or result
No result defined for action com.opensymphony.xwork2.ActionSupport and result xqjhSp错误信息说的很是明白action配置错了

Answer 4

action 不是已经配置上<result name="xqjhSp">/WEB-INF/portal/grad/xqjhSp.jsp</result>  

Answer 5

xqjhSp.jsp如下
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ include file="/common/taglibs.jsp"%>

Answer 6

这错误也太明显了
http://127.0.0.1:8080/pro/login_loginfromsap.action?forward=xqjhSp
这个URL传递的参数forward=xqjhSp
而你的action中的逻辑是
String forward = request.getParameter("forward");
if(forward == null) {
   forward="globalLogin";
}
return forward;
××××××××××××××××××××
执行这个URL，得得forwar参数肯定不为空
那么你最后return的forward=xqjhSp这个result在struts.xml中根本就没有配置，当然跑异常

Answer 7

人家那么大一行
 <result name="xqjhSp">/WEB-INF/portal/grad/xqjhSp.jsp</result>  

Answer 8

<result name="xqjhSp">/WEB-INF/portal/grad/xqjhSp.jsp</result>
干掉试试。
