HTTP Status 404 - No result defined for action and result hello

今天遇到一个诡异的错误.ssh框架搭的项目.

struts.xml文件内容如下:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
 <package name="mypackage" extends="struts-default" >
 
 <action name="upload"    class="net.gicp.yuanpan1987.action.UploadAction">
  <result name="success">/success.jsp</result>
  <result name="input">/upload.jsp</result>
  
  <result name="hello">/success.jsp</result>
 </action>
</package>
</struts>   

 

 

可是在页面返回的时候非说:

HTTP Status 404 - No result defined for action net.gicp.yuanpan1987.action.UploadAction and result hello

 

后来在网上查了一下,说是要在package里加上namespace的属性才行.我记得以前不用加的呀.

加上namespace="/"还真的可以了.郁闷....ing .....
