struts-config.xmlを分割する

分割1

web.xmlにカンマ区切りで複数のstruts-config.xmlを登録する

<servlet>
   <servlet-name>action</servlet-name>
   <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
   <init-param>
     <param-name>config</param-name>
     <param-value>/WEB-INF/struts-config.xml,/WEB-INF/struts-config2.xml</param-value>
   </init-param>
 ...
