Spring MVC .jsp wird nicht automatisch von ViewResolver erstellt

ich bin neu bei Spring MVC.wenn ich das Projekt starte, wird welcome.jsp geöffnet. dann fülle ich das Formular aus und drücke Login. Es ist alles wie es sollte bis jetzt aber dann möchte ich die success.jsp öffnen, wenn die userid ist didem und die passqord ist 123321 wenn nicht dann welcome.jsp sollte wieder öffnen .. aber was ich tatsächlich bekomme 404 ist nicht gefunden weil in der Web-Browser wie dies die uRL Link lautet: http://localhost:8080/CrunchifySpringMVCTutorial/welcome Idk, warum die viewResolver eine .jsp am Ende gesetzt tut .. Jede Hilfe zu schätzen ..Spring MVC .jsp wird nicht automatisch von ViewResolver erstellt

CrunchifyHelloWorld.java Datei würde:

 package com.crunchify.controller; 
    import org.springframework.stereotype.Controller; 
    import org.springframework.web.bind.annotation.RequestMapping; 
    import org.springframework.web.bind.annotation.RequestMethod; 
    import org.springframework.web.bind.annotation.RequestParam; 
    import org.springframework.web.servlet.ModelAndView; 

@Controller 
public class CrunchifyHelloWorld { 


    @RequestMapping(value = "/welcome", method = RequestMethod.GET) 
    public String showLoginForm() { 

     return "welcome"; 
    } 

    @RequestMapping(value = "/welcome", method = RequestMethod.POST) 
    public String verifyLogin(@RequestParam String userID, @RequestParam String password){ 

     ModelAndView model = new ModelAndView(); 
     model.addObject("loginError", "Invalid Id AND/OR password"); 
     if(userID == "didem" && password == "123321") 
     { 
      return "success"; 
     } 
     return "redirect:/"; 



    } 
}

Dies ist nicht in Bezug auf .jsp Suffixed aber etwas, das nicht am richtigen Ort ist! –

Bitte fügen Sie in der erweiterten Projektverzeichnisstruktur des Projekts –

Theres ein Teil "Bildbeschreibung hier eingeben" Ich fügte den Pic Link, aber konnte den DESC nicht entschuldigen :) – Didem

Ihre Servletzuordnung zu folgenden Zeilen ändern und

<servlet-mapping> 
     <servlet-name>crunchify</servlet-name> 
     <url-pattern>/welcome.jsp</url-pattern> 
     <url-pattern>/welcome.html</url-pattern> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping>

zumindest nicht mehr 404 Fehler, aber es öffnet die welcome.jsp ich didem für die Benutzername und 123321 für das Passwort, aber immer noch das "welcome.jsp" öffnen – Didem

Entschuldigung für die späte Antwort. Ich denke, Sie haben das Problem vielleicht gelöst, aber ich möchte trotzdem meine Meinung teilen. Ich denke, das Problem besteht im String-Vergleich. Verwenden Sie die .equals-Methode der String-Klasse. – BeginnersSake

if (userID.equals ("didem") && passwort.equals ("123321")) { zurück "Erfolg"; } – BeginnersSake

Chaneg unten Tag in web.xml und versuchen einmal überprüfen.

<servlet> 
     <servlet-name>crunchify</servlet-name> 
     <servlet-class> 
      org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
    <init-param>

was ist mit Rückkehr "redirect:/{welcome}"; Wie nachfolgend dargestellt.

@RequestMapping(value = "/welcome", method = RequestMethod.POST) 
    public String verifyLogin(@RequestParam String userID, @RequestParam String password){ 

     ModelAndView model = new ModelAndView(); 
     model.addObject("loginError", "Invalid Id AND/OR password"); 
     if(userID == "didem" && password == "123321") 
     { 
      return "success"; 
     } 
     return "redirect:/{welcome}"; 



    } 
}

Ich habe gerade herausgefunden, wo das Problem liegt. wenn ändern wenn zu (1 == 1) {zurück "Erfolg"; } Rückkehr "Willkommen"; dann öffnet es die Erfolgsseite .. so erhält die Anforderung param Sache nicht die Benutzereingabe: D – Didem

gut, aber eine gute Praxis ist, ein Frühlingssicherheitsmuster zu implementieren. –

sicher, ich beginne es einfach – Didem

Spring MVC .jsp wird nicht automatisch von ViewResolver erstellt
