web项目中加载spring容器的方式
1、在Web.xml中，通过ContextLoaderListener加载
?
<context-param>
??? <param-name>contextConfigLocation</param-name>
??? <param-value>/WEB-INF/daoContext.xml /WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
??? <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
?
2、在Web.xml中，通过ContextLoaderServlet加载
<context-param>
??? <param-name>contextConfigLocation</param-name>
??? <param-value>/WEB-INF/daoContext.xml /WEB-INF/applicationContext.xml</param-value>
</context-param>
<servlet>
??? <servlet-name>context</servlet-name>
??? <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
??? <load-on-startup>1</load-on-startup>
</servlet>
3、在struts-config.xml中，通过ContextLoaderPlugIn加载
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
??? <set-property property="contextConfigLocation" value="/WEB-INF/action-servlet.xml,
??????? /WEB-INF/applicationContext.xml"/>
</plug-in>
?
