1、 在Struts2.0 中加载多个 struts.xml ,用<include file="........"></include>
例如：
<struts>
<include file="com/test/user/action/user_struts.xml"></include>
<include file="com/test/shop/action/shop_struts.xml"></include>
</struts>
2、 在Spring 中加载多个 xml ,用 <import resource="........"/>
例如：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<import resource="classpath:com/test/user/dao/user_dao.xml"/>
<import resource="classpath:com/test/shop/dao/shop_dao.xml"/>
</beans>
