struts2的配置之could not find action or result 问题的解决方法(struts.xml文件路径)

struts2的配置中：could not find action or result 问题的解决方法

以上是我的工程目录结构，我把struts.xml没有放到src下，而是根据自己的习惯放到新目录：web-inf/conf/下了。这时候需要在web.xml中进行必要的配置，配置情况如下：

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class>
    <init-param> 
     <param-name>config</param-name> 
     <param-value>struts-default.xml,struts-plugin.xml,/web-inf/conf/struts.xml</param-value> 
    </init-param> 
</filter>

struts.xml内容如下：

<struts>
<package namespace="" name="main" extends="struts-default">
   <action name="ddd" class="test.actiontest">
    <result name="success">index.jsp</result>
   </action>
</package>
</struts>

这时候在ie地址栏中访问：http://localhost:808/test/ddd

时会报错，错误信息如下：

解决办法如下：

只要对web.xml稍做一点改动就行，改成如下：

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter</filter-class>
    <init-param> 
     <param-name>config</param-name> 
     <param-value>struts-default.xml,struts-plugin.xml,../conf/struts.xml</param-value> 
    </init-param> 
</filter>

这样就一切ok了。
