HttpMediaTypeNotAcceptableException / HttpMediaTypeNotAcceptableException: Could not find acceptable representation

Question

I have a API that a client is trying to connect to. However it throws the error:

2015 09 22 04:21:44.297 [org.springframework.web.servlet.mvc.method.annotation.H         


        

Answer 1

I have also faced the same issue.

I have tried to hit the API from android using Volley.

There are 2 different Content-Type. One is Request header Content-Type and other is Body Content-Type. When you initiate a POST or PUT request from the volley, volley take request header and check for body Content-Type. If body Content-Type is not mentioned, volley will add by itself. Volley combines both the Content-Type and our server was able to accept only one Content-Type. But, as volley combines Content-Type for header and body it become "application/json, application/x-www-form-urlencoded; charset=utf-8".

Here, "application/x-www-form-urlencoded" is Content-Type for request body. So, to solve this problem, you can override getBodyContentType() method and return null.

@Override
public String getBodyContentType() {
//return super.getBodyContentType();
    return null;
}

Do not use return "". Using return "" will also throw exception.

[org.springframework.web.servlet.mvc.method.annotation.HttpEntityMethodProcessor] Could not parse Accept header: Invalid token character ',' in token "json, "

Hope this will help.
