http://struts.apache.org/2.3.1.2/docs/webxml.html

根据上面的链接,我们可以在 web.xml 中指定配置文件名。所以我config在下面的映射中添加了参数。

<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.xml</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>*.action</url-pattern>
</filter-mapping>

现在我无法启动 Web 应用程序。以下日志打印在控制台上。

您需要在内部定义struts-default.xmland 。struts-plugin.xml<init-param>

<init-param>
    <param-name>config</param-name>
    <param-value>struts-default.xml,struts-plugin.xml,struts.xml</param-value>
</init-param>

没有它,Struts2 无法找到必要的 bean/results/interceptors/etc。在struts-default.xml文件中定义。当然,您可以将所有声明从默认文件复制到您的配置文件。
