我想向REST网络服务发出POST请求，并想通过POST请求传递客户java对象。但是响应显示415错误代码不支持的媒体类型。
我的REST客户端

Client client = Client.create();
WebResource resource = client.resource("http://localhost:8080/cthix/rest/v1/m2");

Customer cust = new Customer();
cust.setId(101L);
ObjectMapper mapper = new ObjectMapper();
String jsonCustomer = mapper.writeValueAsString(cust);

ClientResponse restResponse = resource.accept("application/json").
                  post(ClientResponse.class,jsonCustomer);

                    System.out.println(restResponse.getStatus());
                    if(restResponse.getStatus()==200){
                        String output = restResponse.getEntity(String.class);
                        PrintWriter pw = response.getWriter();
                        pw.print(output);

                        pw.flush();
                        pw.close();
                    }

我的Rest服务：

@Path(value = "/v1")
public class V1_status {
    @Path("/m2")
    @POST
    @Produces(MediaType.APPLICATION_JSON)
    @Consumes(MediaType.APPLICATION_JSON)
    public Customer returnCustomerDetails(Customer customer){
        Set<Integer> phones = new HashSet<Integer>();
        phones.add(123424541);
        phones.add(123432123);

        List hobbies= new ArrayList();
        hobbies.add("Swimming");
        hobbies.add("coding");;

        customer.setHobbies(hobbies);
        customer.setPhones(phones);
        customer.setCity("Noida");
        customer.setName("abhishek");
        return customer;
    }
}

请指导如何修复它。
