spring 如何加载applicationContext.xml

在web.xml中配置spring

NO1.推荐使用

 <listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener> 

<!--contextConfigLocation在 ContextLoaderListener类中的默认值是 /WEB-INF/applicationContext.xml-->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext.xml</param-value>

<!-- <param-value>classpath:applicationContext*.xml</param-value> -->

</context-param>

Classpath指代的就是 web-inf/classes/ 目录

 

NO2.

 <!--spring3.0之后不再支持此种方式-->

<servlet>

    <servlet-name>context</servlet-name>

    <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>

    <load-on-startup>1</load-on-startup>

</servlet>

 

NO3.

 <!--要导入org.springframework.web.struts-3.0.5.RELEASE.jar包，在struts2.0及以后版本不支持此种方式加载spring-->

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

      <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml"/>

</plug-in>
