注意:struts2配置文件默認存放路徑在/WEB-INF/classes目錄下,即將struts.xml放在src的目錄下。
但是為了協(xié)作開發(fā)與方便管理,我們有時需要把struts.xml放到其他位置
struts2加載配置文件都是先從自己的jar包和/WEB-INF/classes兩個默認的位置加載的。
若修改struts2配置文件的存放位置,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>
在這里我把struts.xml放在了src下的resources/struts2包下，因為設置了<param-name>config</param-name>參數(shù),所以struts-default.xml,struts-plugin.xml等原來struts2默認加載的文件也需要手動指定,否則不會自動加載。
若不在這里配置struts-default.xml,struts-plugin.xml,也可在struts.xml文件中include將兩個文件包含進來。
<include file="struts-default.xml" />
<include file="struts-plugin.xml" />
如若約定大于配置,多個子配置文件的話可以采用掃描的方式如：
<include file="com/home/conf/struts-*.xml" />
或直接
<include file="com/home/conf/*.xml" />
