读取Spring配置文件的方式
1.在StrutsConfig.xml文件中以插件的形式来读取
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/classes/applicationContext.xml"/>
</plug-in>
2.在web.xml文件中通过监听器的形式来读取
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/applicationContext.xml
</param-value>
</context-param>
