REST如何发出POST请求

Question

我试图从客户端发布xml并从我的服务中使用xml。当我尝试以下代码时，我得到不支持的媒体类型异常。 我试着效仿这个例子： http://examples.javacodegeeks.com/enterprise-java/rest/jersey/xml-example-with-jersey-jaxb/ 我究竟做错了什么 ？有任何想法吗 ？

客户方：

  private void request(String url,Event event) throws IOException, SAXException {
            try {

                Client client = Client.create();
                ClientResponse response = null;
                WebResource webResource = client
                        .resource(url);
                    if(event != null){

                     response = webResource.accept("application/xml")
                                .post(ClientResponse.class,event);

                }else{
                 response = webResource.accept("application/xml")
                        .get(ClientResponse.class);
                }
                if (response.getStatus() != 200) {
                    throw new RuntimeException("Failed : HTTP error code : "
                            + response.getStatus());
                }

                String output = response.getEntity(String.class);

                System.out.println("Output from Server .... \n");
                System.out.println(output);

            }catch (Exception e) {

                e.printStackTrace();

            }

服务器端：

@POST
    @Path("/created")
    @Consumes({"application/xml", MediaType.APPLICATION_FORM_URLENCODED,"text/html"})
    @Produces ({"application/xml", MediaType.APPLICATION_FORM_URLENCODED,"text/html"})
    public Response createEvent( @FormParam("eventtitle") String title,
            @FormParam("eventtype") String type,
            @FormParam("eventdescription") String description,
            @FormParam("eventlocation") String location,
            @FormParam("eventdate") String date,
            @FormParam("eventcreationdate") String creationdate,
            @FormParam("eventmodificationdate") String modificationdate,
            @Context HttpServletResponse servletResponse) throws IOException {
        final StringBuilder sb = new StringBuilder();
        sb.append( "<h4>Event sucessfully created </h4>");
        sb.append("<br></br><li><p><a href=\"/\">go back</a></p></li>");
        Response.status(200).entity(sb.toString()).build();
        Event event = eventWorker.createEvent(title,type,description,location,date,
                creationdate,modificationdate);
        return Response.ok(sb.toString()).cacheControl(CC).build();
    }
