validation.xml之前的拦截器

我们知道ActionClassName-validation.xml是在ActionClassName.java之前执行的

现在我有一个拦截器，它在ActionClassName.java之前执行

执行顺序为：

ActionClassName-validation.xml 拦截器 ActionClassName.java 我的问题是：有可能有以下顺序吗

拦截器 ActionClassName-validation.xml ActionClassName.java 在我的struts.xml中，我有以下配置：

<interceptor class="com.myproject.user.interceptor.PermissionInterceptor"    name="PermissionInterceptor"></interceptor>
<interceptor-stack name="permissionStack">
        <interceptor-ref name="defaultStack"/> 
    <interceptor-ref name="PermissionInterceptor" />
</interceptor-stack>

<action name="addCommentAction" class="com.myproject.action.AddCommentAction">
    <interceptor-ref name="permissionStack" />
    <result name="success">homePage.jsp</result>
    <result name="error">homePage.jsp</result>          
    <result name="login">login.jsp</result>
    <result name="input">addComment.jsp</result>
</action>

提前感谢,， Nabil

在struts.xml中

您可以通过更改顺序将它们放在struts.xml中，如下所示

<package name="mydefault" namespace="/" extends="struts-default">
    <interceptors>
        <interceptor name="yourInterceptor" class="YourPackage.YourInterceptorClass"></interceptor>
        <interceptor-stack name="myStack">
            <interceptor-ref name="exception"/>
            <interceptor-ref name="alias"/>
            <interceptor-ref name="servletConfig"/>
            <interceptor-ref name="prepare"/>
            <interceptor-ref name="i18n"/>
            <interceptor-ref name="chain"/>
            <interceptor-ref name="debugging"/>
            <interceptor-ref name="profiling"/>
            <interceptor-ref name="scopedModelDriven"/>
            <interceptor-ref name="modelDriven"/>
            <interceptor-ref name="fileUpload"/>
            <interceptor-ref name="checkbox"/>
            <interceptor-ref name="staticParams"/>
            <interceptor-ref name="actionMappingParams"/>
            <interceptor-ref name="params">
                  <param name="excludeParams">dojo\..*,^struts\..*</param>
            </interceptor-ref>
            <interceptor-ref name="conversionError"/>

            /*putting your interceptor in between or any order */                
            <interceptor-ref name="yourInterceptor" />

            <interceptor-ref name="validation">
                <param name="excludeMethods">input,back,cancel,browse</param>
            </interceptor-ref>
            <interceptor-ref name="workflow">
                <param name="excludeMethods">input,back,cancel,browse</param>
            </interceptor-ref>
            <interceptor-ref name="paramsPrepareParamsStack" />

            <interceptor-ref name="validationWorkflowStack" />
            .... Other interceptors
        </interceptor-stack>
</interceptors>
<default-interceptor-ref name="myStack"/>
...Other actions
</package>

因此，更改拦截器堆栈中的顺序。问题是什么？你说得对@AleksandrM。谢谢！！

<interceptor-stack name="defaultStack">
            <interceptor-ref name="exception"/>
            <interceptor-ref name="alias"/>

            <interceptor-ref name="prepare"/>
