Jfinal using interceptors to tell different browsers to return different results pages

1. Objective

   The front-end made two sets of pages, a set of PCs, a set of mobile phones, I want to program the returned pages, and the controller does not need to care about the terminal, only a fixed string of render.

2. Method of Thinking

   Interceptor intercepts to render, then modifies Viewpath

3. Realize

   Key code

   
   

Public class appconst {    public static routes system_ routes = null ;} Public class cmsconfig extends jfinalconfig {    public void  configconstant (constants constants)  {         Configutil.loadconfig (Loadpropertyfile ("Application-test.properties",  "Application.properties",  const.default_encoding));         constants.setbaseviewpath ("/WEB-INF/ Page ");    }        public void  Configinterceptor (interceptors interceptors)  {    interceptors.add (new  Renderswitchinterceptor ());} }        public class webroute extends routes  {     @Override     public void config () &nbSp {        add ("/web/product", Webproductctrl.class, "web/product");     }}/** * PC  and Mobile   page auto-switching   key code  * created by yangtao  on 2015-8-31. */public class RenderSwitchInterceptor implements  interceptor {     @Override     public void intercept ( Invocation ai)  {        Controller c =  Ai.getcontroller ();         ai.invoke ();         render render = c.getrender ();         string returnpath = render.getview ();  // ctrl string in Render          String viewPath =  "";         if  (!returnpath.startswith ("/")) { //  is not the full path of the page if it does not begin with/start              viewpath = appconst.system_routes.getviewpath (Ai.getcontrollerkey ());         }        if  (IsMobile (C.getrequest ())) {  //Mobile             viewPath =  Viewpath.replace ("/web/", "/wap/");        }         render.setview (Viewpath+returnpath);     }  }
