struts2 如何自定义struts.xml配置文件的存放位置

    假设你要把struts.xml配置文件存放在/WEB-INF/config目录下，web.xml作如下配置即可：
web.xml

<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-default.xml,struts-plugin.xml,../config/struts.xml</param-value>
        </init-param>
</filter>
<filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>
