1.1 ContextLoaderListener spring容器 根上下文(可以作為 父容器 ApplicationContext)
1.2 servlet裡init-param 比如springmvc配置(子容器)
1.3 舉例 web.xml
<!--父 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--子 --> <servlet> <servlet-name>mvc-manage</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/mvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet>
