  – Web app deployment descriptor that just loads an "example" DispatcherServlet
  – with a specific context.
  –
  – Depends on the following libraries in WEB-INF/lib:
  – * spring.jar
  – * commons-logging.jar
  –>
<web-app>

  <!–
    – Servlet that dispatches request to registered handlers (Controller implementations).
    – Has its own application context, by default defined in "{servlet-name}-servlet.xml",
    – i.e. "example-servlet.xml".
    –
    – A web app can contain any number of such servlets.
    – Note that this web app does not have a shared root application context,
    – therefore the DispatcherServlet contexts do not have a common parent.
    –>
<servlet>
  <servlet-name>example</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
  </servlet>

  <!–
    – Maps the example dispatcher to /example/*. All handler mappings in
    – example-servlet.xml will by default be applied to this subpath.
    – If a mapping isn’t a /* subpath, the handler mappings are considered
    – relative to the web app root.
    –
    – A single dispatcher could get mapped to multiple paths, like any servlet.
    –>
<servlet-mapping>
    <servlet-name>example</servlet-name>
    <url-pattern>/example/*</url-pattern>
  </servlet-mapping>
  <welcome-file-list>
  <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

  – Application context definition for "example" DispatcherServlet.
  –>
<beans>

<!–
   – Due to the dispatcher mapping in web.xml and the default BeanNameUrlHandlerMapping
   – in this context, "http://localhost/example/test" will trigger this controller.
   –
   – Due to the default InternalResourceViewResolver, returned view names get treated
   – as internal resources, e.g. JSPs: "/test.jsp" or "/WEB-INF/jsp/test.jsp" will
   – render the respective file. So with the default resolver, controllers have to
   – specify the whole resource path as view name (see below for an alternative).
   –
   – HandlerMapping and ViewResolver are simple interfaces: Choose one of Spring’s
   – provided implementations, or write your own one.
   –
   – A very simple Controller implementation could look as follows:
   –
   -   public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) {
   -     return new ModelAndView("/test.jsp");
   -   }
   –
   – Or for writing the response directly:
   –
   -   public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) {
   -     response.getWriter().write("This is a test");
   -     return null;
   -   }
    –>
<bean name="/test" class="example.ExampleController"/>

<!–
   – Optional: Explicit InternalResourceViewResolver definition,
   – specifying view class, name prefix, and name suffix.
   –
   – Specifying the JstlView class instead of the default InternalResourceView
   – exports Spring’s message source and the current user locale as standard
   – JSTL attributes, to be leveraged by JSTL fmt tags.
   –
   – A prefix/suffix combination allows for symbolic view names to be returned
   – by controllers, still getting straightly mapped to internal resources.
   – Example: view name "test" -> resource "/WEB-INF/jsp/test.jsp".
   –
   – For more sophisticated mappings, consider ResourceBundleViewResolver
   – (see "webapp-typical" skeleton) or XmlViewResolver.
