java - Request resource not found when run Spring 4 controller on Tomcat -

i try run simple code can't seem work , call controller

@configuration @enablewebmvc @componentscan(basepackages = "com.mypackage") public class appconfig extends webmvcconfigureradapter {     public void configureviewresolvers(viewresolverregistry registry) {          internalresourceviewresolver viewresolver = new internalresourceviewresolver();         viewresolver.setviewclass(jstlview.class);         viewresolver.setprefix("/web-inf/views/");         viewresolver.setsuffix(".jsp");         registry.viewresolver(viewresolver);     }      /**      * configure resourcehandlers serve static resources css/ javascript etc...      */     @override     public void addresourcehandlers(resourcehandlerregistry registry) {         registry.addresourcehandler("/static/**").addresourcelocations("/static/");     }  } 

this configuration file have controller in com.mypackage follows:

@controller @requestmapping("/") public class testcontroler {      @autowired     appdataservice appdataservice;      @requestmapping(value = "/hello")     public model register(model model){           model.addattribute("name", "y");         return model;     }      @requestmapping("/")     public string index(modelmap model){          date start = new date();         system.out.println(start);         list<appdata> app = appdataservice.getlistappdata();         date end = new date();         system.out.println(end);          string result = "";         (object : app) {             result+=a+" <br>";         }          model.addattribute("name", result);          return "hello";     } } 

and have added hello.jsp. when run project on tomcat server through eclipse don't hello.jsp resource not found, error 404. not sure doing incorrect here how understand should getting start page hitting controller because of @requestmapping("/") not sure wrong or goes wrong here.

i have annotation version of web.xml follows:

public class appinitializer extends abstractannotationconfigdispatcherservletinitializer {      @override     protected class<?>[] getrootconfigclasses() {         return new class[] { appconfig.class };     }      @override     protected class<?>[] getservletconfigclasses() {         return null;     }      @override     protected string[] getservletmappings() {         return new string[] { "/" };     }  } 

1). remove 1 more @requestmapping("/") above testcontroler class, because produces double mapping since it's there in index() method.

2). modify configureviewresolvers() return viewresolver object instead. annotate @bean :

@bean public viewresolver configureviewresolvers() {          internalresourceviewresolver viewresolver = new internalresourceviewresolver();         viewresolver.setviewclass(jstlview.class);         viewresolver.setprefix("/web-inf/views/");         viewresolver.setsuffix(".jsp");         return viewresolver ;     } 

like :

@configuration @enablewebmvc @componentscan(basepackages = "com.mypackage") public class appconfig extends webmvcconfigureradapter {     @bean    public viewresolver configureviewresolvers() {          internalresourceviewresolver viewresolver = new internalresourceviewresolver();         viewresolver.setviewclass(jstlview.class);         viewresolver.setprefix("/web-inf/views/");         viewresolver.setsuffix(".jsp");         return viewresolver ;     }      /**      * configure resourcehandlers serve static resources css/ javascript etc...      */     @override     public void addresourcehandlers(resourcehandlerregistry registry) {         registry.addresourcehandler("/static/**").addresourcelocations("/static/");     }  }
