415 Unsupported Media Type The request entity has a media type which the server or resource does not support. For example, the client uploads an image as image/svg+xml, but the server requires that images use a different format. can you post the message which is being sent? — Moshe Arad, Apr 11 '17 at 20:05
You should add the DTO object structure here. Model class is not required. — gaganbm, Apr 11 '17 at 21:22
I have added the answer. You can try through curl or postman, and set proper headers. — gaganbm, Apr 11 '17 at 21:31
I added Context-Type:application/json to header on postman and post data.Error changed now 500 @gaganbm — real, Apr 11 '17 at 21:51
May be it is a typo at your end. It is not `Context-type`, it is `Content-type`. Secondly, 500 could mean anything, like it is not able to save it in the database, or may be a null pointer exception somewhere! But the original problem of `415 media type` seems to be solved. — gaganbm, Apr 11 '17 at 21:58
no, if i add "Context-Type:application/json" to postman header, 415 error solved.But my code still 415 error @gaganbm — real, Apr 11 '17 at 22:04
And if it is getting solved from `postman`, and you are still seeing the 415 error, then it must be a problem in the client that you are using. Your javascript client or curl or whatever. — gaganbm, Apr 11 '17 at 22:12
Like I said, if 415 error is gone from postman, but it is coming from any other client, you need to check how you are sending the request headers. — gaganbm, Apr 11 '17 at 22:16

If you are trying the call in POSTMAN add Content-Type: application/json as header parameter.

HTTP 415 comes when

The origin server is refusing to service the request because the payload is in 
a format not supported by this method on the target resource.

Ref : https://httpstatuses.com/415

You need to set the request header correctly. As per the image you have attached, you are passing Content-Type: application/x-www-form-urlencoded. But your code expects application/json.

My error's reason is this backbone code:

Backbone.emulateJSON = true;

If Backbone.emulateJSON=true , Content-Type= application/x-www-form-urlencoded.

Now Backbone.emulateJSON=false; Problem is solved!

    @POST
    @Produces(MediaType.APPLICATION_JSON+ ";charset=UTF-8")
    @Consumes(MediaType.APPLICATION_JSON)
        public TravelDTO save(TravelDTO dto) {
        dto.setUser(userService.get(dto.getUser().getUserID()));
          dto.setTravelStart(new Date());
          dto.setTravelEnd(new Date());

          return travelService.save(dto);
        }

you're returning: return travelService.save(dto);

and you declared that you're returning an HTTP JSON,

then just add to your controller the annotation @RestController instead of @Controller.

or just add to your method the @ResponseBody annotation.

I'm using Rest.So i have no controller class.I have just (model, service, resource,dao and dto) But i am added @ResponseBody to the POST method but same 415 error continued – real Apr 11 '17 at 20:53
What do you mean "I have no controller"? if you don't use controllers with Spring how do you expect from your server to receive requests from end users? – Moshe Arad Apr 11 '17 at 20:55
https://gist.github.com/berat703/1b54549eecfc4e09534fe1b24e824591 .My Service class expect from my server to receive requests form end users.Should i do delete "@Service" and add "@RestController" ? – real Apr 11 '17 at 21:12
i don't find the solution.Sorry for disturb :( – real Apr 11 '17 at 22:12
