pass javascript response variable to spring controller function

Question

The following javascript code works with the facebook login window appearing and allowing a user to login. The response values are captured and I know it works as alerts appear where setup but I cannot pass the value back to a controller method.

 @RequestMapping(value ="/getAccessToken" , method = RequestMethod.POST)
 public @ResponseBody String getAccessToken(@RequestBody String token){

     System.out.println(token);

     return token;
  }

Javascript method called:

    function doLogin() {
        FB.login(function(response) {
        alert(response);
        console.log(response);
        if (response.authResponse) {
                    alert(response.authResponse.userID);
                    alert(response.authResponse.accessToken);
                    var Token = response.authResponse.accessToken;
                    alert(Token);
                    $.ajax({
                        type: "POST",
                        url: "/HelloController/getAccessToken",
                        data: Token,
                        success: function (result) {
                              alert("Token");
                        },
                        error: function (result) {
                              alert("oops");
                        }
                    });
                     document.getElementById('loginBtn').style.
         display = 'none';
         getUserData();
        }}, {perms:'manage_pages', 
       scope: 'email,public_profile', return_scopes: true});
     };

The error I get is the following:

WARN 25660 --- [nio-8080-exec-9] 
o.s.web.servlet.PageNotFound             : 
Request method 'POST' not supported

Appreciate responses.

is your controller annotated with @RequestMapping("/HelloController") ? — reos, Dec 07 '15 at 20:58
@RequestMapping(value ="/HelloController" , method =RequestMethod.POST) public String getAccessToken( — vbNewbie, Dec 07 '15 at 23:01
Could you also post your Spring dispatch configuration? Are you using any url pattern such as *.html? — dreamwagon, Dec 10 '15 at 21:12
Please add the response and what data is sent during the request. — Pablo Jomer, Dec 14 '15 at 08:55

The problem could be that you are using a new version of JQuery that sends request data as post form data instead of JSON as default. Try changing your ajax call to the following. The form data would not be recognized by your controller so if this is the case you should see a 404.

$.ajax({
        type: "POST",
        traditional: true,
        url: "/HelloController/getAccessToken",
        data: JSON.stringify(Token),
        success: function (result) {
           alert("Token");
        },
        error: function (result) {
          alert("oops");
        }
      });

For reference see this post: Send JSON data via POST (ajax) and receive json response from Controller (MVC)

Did this help you? Please accept the answer if it did. – Pablo Jomer Dec 14 '15 at 17:35
Sorry for the late follow up & I did eventually figure it out but will accept your answer. Thanks – vbNewbie Dec 23 '15 at 21:06
I'm sorry; I revisited this program and still getting the same error. – vbNewbie Jan 06 '16 at 17:35
Please provide some more info. This solved the problem for me in a similar setup. – Pablo Jomer Jan 06 '16 at 20:37
sorry Pablo. I found the issue and it was the controller mapping value that needed to match the url call in the ajax function. thanks. – vbNewbie Jan 07 '16 at 15:28
Good for you! :D Don't forget to answer your own question. – Pablo Jomer Jan 07 '16 at 15:47
