Springboot Controller redirect not working

Question

I am trying a quick prototype using Spring boot.

I have the following Controller code minus the imports

@EnableAutoConfiguration
@RestController
@Controller
public class IndexController{
    @RequestMapping(value = "/")
    public ModelAndView firstPage(HttpServletRequest request, HttpServletResponse response){
        ModelAndView mv = new ModelAndView("index");
        mv.addObject("message", Calendar.getInstance().getTime().toString());
        return mv;
    }
    @RequestMapping(value="/gotoNextPage",method = RequestMethod.GET)
    public  ModelAndView gotoNextPage(HttpServletRequest request, HttpServletResponse response){
        System.out.println("Inside gotoNextPage!!!!!!");
        ModelAndView mv = new ModelAndView("redirect:nextpage");
        mv.addObject("message", "next page");
        return mv;
    }
}

From my HTML, I invoke the /gotoNextPage and in my Server, I see the Inside gotoNextPage!!!! print statement. However, the nextPage doesn't load. If I don't use redirect and I type http://localhost:8080/gotoNextPage, the HTML content loads fine. Also, the index.html also loads fine

I am using spring boot mvc, thymeleaf, angularjs

My project structure is shown below: enter image description here

Please help.

Thanks in advance.

A redirect is client side, so what you pass after the redirect: should lead to a valid URL not a view name... And stop mixing versions you are mixing Spring Boot 1.2.0 and 1.2.7. Change the parent to 1.2.7 and remove the versions elsewhere. — M. Deinum

@M.Deinum: Thanks for bringing up the discrepancy in version numbers. I have corrected that. I changed the redirect to say ModelAndView mv = new ModelAndView("redirect:nextpage.html"); and also moved the nextpage.html under the static folder in my project structure. It doesn't work. I also tried "redirect:/nextpage.html". Both of them didn't work. I tried localhost:8080/nextpage.html and the content loads up fine. — supreethmurthy

You have both @RestController and @Controller which is it... Judging from your return types you need @Controller not @RestController. Also the @EnableAutoConfiguration is useless on this class. — M. Deinum

I'd try to simplify the method to use Model and return a simple String:

@RequestMapping(value="/gotoNextPage",method = RequestMethod.GET)
public String gotoNextPage(Model model){
    LOG.debug("Inside gotoNextPage!!!!!!");
    model.addAttribute("message", "next page");
    return "redirect:nextpage.html";
}

I tried your code. That isn't working. I have placed the nextpage.html in the static folder. The function is being hit and I see the sys out. But the page isn't redirecting.

daniel.eichten Over a year ago

It seems that you do have a different issue. Can you check the Http headers? Can you get the nextpage when you open it in the browser directly?

supreethmurthy Over a year ago

Yes. I am able to open the page directly on the browser. Also in my controller method, if I don't use redirect, I am able to invoke the contents of nextpage directly when I type /gotoNextPage on the browser. The other thing that is baffling me is if I type redirect:www.google.com, I don't see google.com on my browser either. It seems like the controller is able to redirect but the browser is not reloading the page. Am I missing any configuration in the property file? Thanks for your help.

VadymVL Over a year ago

@supreethmurthy, you should use full URL, like this redirect:http://www.google.com for redirect to external page.

supreethmurthy Over a year ago

I looked at the http headers. I am getting a status of 200, which is correct. But I am making a call through XmlHttpRequest on the client side. Could that be causing the problem?

Try to use RedirectView explicite

@RequestMapping(value="/gotoNextPage",method = RequestMethod.GET)
public  ModelAndView gotoNextPage(HttpServletRequest request, HttpServletResponse response){
    System.out.println("Inside gotoNextPage!!!!!!");

    ModelMap model = new ModelMap();
    model.add("message", "next page");
    return new ModelAndView(
       new RedirectView("/nextpage", true),
       //or new RedirectView("/nextpage.html", true),
       model
    );
}

I tried redirecting to another controller method instead of an html file and the redirected controller method is hit. I see a sys out from the new method. In the new method, I tried redirect, forward and also generic way like this. ModelAndView mv = new ModelAndView("nextpage"); mv.addObject("message", Calendar.getInstance().getTime().toString()); return mv; This isn't working either. From the new controller, the page isn't loaded. There is no error on the console either.

It's old but reading this I would say that the browser has reached the final result, while your spring application continued the execution..

If you want to use "redirect:" with springboot,You must inject "InternalResourceViewResolver".Although Spring Boot provides auto-configuration,if you use "@EnableWebMvc","InternalResourceViewResolver" will not inject.look here

If you are trying to redirect and it does not work, remember that you mustn't put the @ResponseBody annotation.

So, this will not work:

@PostMapping(value = "/agregar")
@ResponseBody // Annotation here
public String guardarProducto() {
    // magic here
    return "redirect:/productos/mostrar";
}

But this will do (remove the @ResponseBody Annotation):

@PostMapping(value = "/agregar")
public String guardarProducto() {
    // magic here
    return "redirect:/productos/mostrar";
}

More info about redirect in Spring Boot here.

The problem was making a call through xmlhttprequest object on the client end. I had to handle the completion of the event. I got rid of the $http.get call on the client and did a window.location.href instead. My controller redirects and the page loads automatically.
