Struts 2.3 忽略通配符操作

Question

我正在设置一个使用 Struts 2.3 和 Tiles 2 的应用程序。一些页面将受到 Struts 的严重驱动（例如，大量的 CRUD），而其他页面将是简单的静态 HTML/JSP 页面。我想设置一些处理特定功能的操作并将所有其他 URL 发送到 default 操作，该操作将根据提供的路径检查是否存在适当的静态页面。如果没有，则会生成 404 错误或类似的错误。

在struts.xml 中，我应用了一个看起来应该可以工作的基本配置；然而，Struts 似乎忽略了通配符操作。非通配符操作工作得很好。

这是struts.xml：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

下面是我收到的错误示例：

我错过了什么或做错了什么？

Answer 1

由于您使用的是advanced wildcards，因此您的操作名称应该是与配置匹配的有效正则表达式。

像这样

<action name="{.*}" class="com.installation.action.PageAction">
   <result type="tiles">standard-page</result>
</action>
