注意:struts2配置檔案預設存放路徑在/WEB-INF/classes目錄下,即將struts.xml放在src的目錄下。
但是為了協作開發與方便管理,我們有時需要把struts.xml放到其他位置
struts2載入配置檔案都是先從自己的jar包和/WEB-INF/classes兩個預設的位置載入的。
若修改struts2配置檔案的存放位置,在web.xml配置過慮器,具體配置如下：

<init-param>
  <param-name>config</param-name>
  <param-value>struts-default.xml,
struts-plugin.xml,resources/struts2/struts.xml</param-value>
</init-param>

在這裡我把struts.xml放在了src下的resources/struts2包下，因為設定了<param-name>config</param-name>引數,所以struts-default.xml,struts-plugin.xml等原來struts2預設載入的檔案也需要手動指定,否則不會自動載入。

若不在這裡配置struts-default.xml,struts-plugin.xml,也可在struts.xml檔案中include將兩個檔案包含進來。

<include file="struts-default.xml" />
<include file="struts-plugin.xml" />

如若約定大於配置,多個子配置檔案的話可以採用掃描的方式如：

<include file="com/home/conf/struts-*.xml" />
或直接
<include file="com/home/conf/*.xml" />
