Spring MVC: Redirect in @ResponseBody

Question

I want to redirect to another .jsp in spring mvc method. I don't want to use javascripts methods like: window.location.replace(url).

My method:

@RequestMapping(value= "loginUser", method=RequestMethod.POST)
public @ResponseBody String loginUser (@RequestParam("name") String name,   @RequestParam("password") String password){ 

   return "";
}

Include an HttpServletResponse parameter and call sendRedirect(String).

Or, don't use @ResponseBody at all, and return the model/view you want to use.

@Responsebody is essential in my case, I included an HttpServletResponse and called sendRedirect(String) and it dosen't work. :( – karolinski Apr 25 '16 at 13:35
Are you sure it's essential? What do you return when this call doesn't redirect? – OrangeDog Apr 25 '16 at 14:21
else { response.sendRedirect(TApi.Navigation.ANOTHER_JSP); } response.sendRedirect(TApi.Navigation.GET_APP_PAGE); – Oleksii Kyslytsyn Mar 26 '20 at 03:24

You can't do the redirect from Spring when your request expects json response. You can set a parameter for redirect so that when you enter the success block you can check the parameter to redirect using window.location.reload();. For example, from a similar post, check this answer,

Redirect on Ajax Jquery Call

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
});

You can alternatively add a response header for redirect like response.setHeader("REQUIRES_AUTH", "1") and in jQuery success,

success:function(response){ 
        if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
            window.location.href = 'login.htm'; 
        }
        else {
            // Process the expected results...
        }
    }

Refer the similar question: Spring Controller redirect to another page

@OrangeDog seems it won't working either. As spring doesn't redirect to another page on json requests. Updated an alternative solution. — Lucky, Apr 25 '16 at 14:11
I assumed the OP is using ajax call to login the user and redirect to some success page. Anyway whether or not he uses ajax, it can only be done is JS as the other posts suggests. — Lucky, Apr 25 '16 at 14:18
