ApplicationContext创建方式

ApplicationContext能以声明的方式创建,可以使用ContextLodaer接口及其实现,它有两个实现:ContextLoaderListener和ContextLoaderServlet, 注意ContextLoaderListener不能与servlet2.2兼容,下面是具体实现

xml 代码

<context-param>
  <param-name> contextConfigLocation</param-name>
  <param-value>/web-inf/applicationContex.xml</param-value>
</context-param>
<listener>
   <listener-class>org.springframework.web.contex.ContexLoaderLister</listener-class>
</listener>
<!—or use the ContextLoaderServlet instead of the above listener
<servlet>
<servlet-name>context</servlet-name>
<servlet-class> org.springframework.web.contex.ContexLoaderServlet</servlet-class>
</servlet>
