用于友好URL的Struts2递归通配符映射

Question

    <action name="en/articles/categories/*" class="it.cms.article.action.SearchArticleCustom">
        <param name="locale">en</param>
        <param name="categoryFriendlyUrl">{1}</param>
        <result name="success">/pages/article/search_article.jsp</result>
    </action>

    <action name="en/articles/categories/*/*" class="it.cms.article.action.SearchArticleCustom">
        <param name="locale">en</param>
        <param name="categoryFriendlyUrl">{2}</param>
        <result name="success">/pages/article/search_article.jsp</result>
    </action>

    <action name="en/articles/categories/*/*/*" class="it.cms.article.action.SearchArticleCustom">
        <param name="locale">en</param>
        <param name="categoryFriendlyUrl">{3}</param>
        <result name="success">/pages/article/search_article.jsp</result>
    </action>

所以，我的情况是类别可以嵌套而没有限制。 当前的struts-config文件对于3级子类别非常有用。

我是否可以将此代码设置为“递归”以涵盖无限级别的子类别？

完全未经测试，但我会尝试类似的事情：

<action name = "en/articles/categories**/*" 
       class = "it.cms.article.action.SearchArticleCustom">

    <param  name = "locale">en</param>
    <param  name = "categoryFriendlyUrl">{2}</param>

    <result name = "success">/pages/article/search_article.jsp</result>

</action>
