Struts注册Spring Context的三种方式

（1）使用Struts插件

         在struts-config.xml中
       

  <plug-in className="org.springframework.web.struts.ContextLoaderPlugin">
    <set-property property="contextConfigLocation"
                  value="applicationContext.xml"/>
  </plug-in>

（2）在web.xml中使用Listener

 

<context-param>
  <param-name>contextConfigLocation</param-name>
        <param-value>
    /WEB-INF/classes/applicationContextxml,
        </param-value>
</context-param>
<listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>     

 （2）在web.xml中使用Servlet

<servlet-name>springInitServlet</servlet-name>
<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>0</load-on-startup>
