Question

使用Eclipse配置Struts 2。我很难让它正常工作。据我所知，它可以找到该文件，但它无法加载配置文件。我究竟做错了什么？我已经清理了程序，所有maven依赖项似乎都在那里。我有另一个工作项目，说实话，一切看起来都是相同的，除了一个有效，而这一个没有。

你不应该在新项目中使用FilterDispatcher，这个很久以前就已被弃用了。当前的struts2过滤器类可以在web.xml中配置为

<filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    <init-param>
        <param-name>actionPackages</param-name>
        <param-value>com.manifestcorp.sunday</param-value>
    </init-param>
</filter>

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

注意，init参数允许您指定要扫描操作类的包。
