POST JSON fails with 415 Unsupported media type, Spring 3 mvc

Question

I am trying to send a POST request to a servlet. Request is sent via jQuery in this way:

var productCategory = new Object();
productCategory.idProductCategor

I had the same problem. I had to follow these steps to resolve the issue:

1. Make sure you have the following dependencies:

    
        com.fasterxml.jackson.core
        jackson-core
        ${jackson-version} // 2.4.3
    
    
        com.fasterxml.jackson.core
        jackson-databind
        ${jackson-version} // 2.4.3
    

2. Create the following filter:

    public class CORSFilter extends OncePerRequestFilter {

        @Override
        protected void doFilterInternal(HttpServletRequest request,
                                        HttpServletResponse response, FilterChain filterChain)
                throws ServletException, IOException {

            String origin = request.getHeader("origin");
            origin = (origin == null || origin.equals("")) ? "null" : origin;
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, PUT, UPDATE, DELETE, OPTIONS");
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Headers",
                    "Authorization, origin, content-type, accept, x-requested-with");

            filterChain.doFilter(request, response);
        }
    }

3. Apply the above filter for the requests in web.xml

    
        corsFilter
        com.your.package.CORSFilter
    
    
        corsFilter
        /*
    

I hope this is useful to somebody.
