注意:struts2配置文件默认存放路径在/WEB-INF/classes目录下,即将struts.xml放在src的目录下。
但是为了协作开发与方便管理,我们有时需要把struts.xml放到其他位置
struts2加载配置文件都是先从自己的jar包和/WEB-INF/classes两个默认的位置加载的。
若修改struts2配置文件的存放位置,在web.xml配置过虑器,具体配置如下：
<init-param>
<param-name>config</param-name>
<param-value>struts-default.xml,
struts-plugin.xml,resources/struts2/struts.xml</param-value>
</init-param>
在这里我把struts.xml放在了src下的resources/struts2包下，因为设置了<param-name>config</param-name>参数,所以struts-default.xml,struts-plugin.xml等原来struts2默认加载的文件也需要手动指定,否则不会自动加载。
若不在这里配置struts-default.xml,struts-plugin.xml,也可在struts.xml文件中include将两个文件包含进来。
<include file="struts-default.xml" />
<include file="struts-plugin.xml" />
如若约定大于配置,多个子配置文件的话可以采用扫描的方式如：
<include file="com/home/conf/struts-*.xml" />
或直接
<include file="com/home/conf/*.xml" />
