Error 415 - Unsupported Media Type with Spring 4

Question

I am upgrading Spring from version 3 (XML based) to 4.2.4 (annotation based)

Controller

@RestController
public class XnetOrderResourceController{
    @Autowired
    private XnetOrderDao orderDao;

    /*
     * GET All Orders
     */
    @RequestMapping(value = "/getAllOrdersInfo", method =RequestMethod.GET, produces="application/json")
     public XnetOrder  get(@RequestParam("Id") Long Id) {
        XnetOrder order=null;
        try{
            if(MiscUtils.isNotEmpty(Id)){
                order=orderDao.get(Id);
            }
        }catch(HibernateException e){
            log.info(ORDER_DETAIL_NOT_AVAILABLE);  
            getLogger().error(e.getMessage());
        }

        return   order;
    }

    /*
     * POST(create new) Orders
     */
    @RequestMapping(value = "/insertOrders", method =RequestMethod.POST,  consumes="application/json", produces="application/json")
    public void post(@RequestBody XnetOrder order){
        try{            
            orderDao.post(order);
        }catch(HibernateException e){
            log.info("Creating the Order  operation failed.");
            getLogger().error(e.getMessage());
        }
    }

     /*
      * PUT (update) orders 
      */
    @RequestMapping(value="/updateOrders", method=RequestMethod.PUT, consumes="application/json", produces="application/json")
    public XnetOrder update(@RequestBody XnetOrder order){
        try{
            order=orderDao.put(order);
        }catch(HibernateException e){
            getLogger().error(e.getMessage());
        }

        return order;
    }

    /*
     *  DELETE orders
     */
    @RequestMapping(value="/deleteOrders",method=RequestMethod.DELETE)
    public void delete(@RequestParam("Id") Long Id){
        try{
            if(MiscUtils.isNotEmpty(Id)){
                orderDao.delete(Id);
                log.info("Order is successfully deleted");
            }
        }catch(HibernateException e){
            log.info(XNET_PRODUCT_INVALID_ERROR_MESSAGE);
            getLogger().error(e.getMessage());
        }
    }
}

JAR files in my classpath are -

jackson-annotations-2.2.3.jar, 
jackson-core-2.2.3.jar, 
jackson-databind-2.3.3.jar, 
jackson-mapper-asl-1.9.13.jar, 
jackson-2.1.0-all.jar

I am able to perform GET operation, which successfully returns JSON value, but PUT and POST operations don't work. I am using Postman as a REST client. I also tried passing the URL for PUT operation after setting the header value Content-Type to aplication/json but it always returns

Error 415 - Unsupported Media Type.

I am getting the following response headers:

Connection     → close
Content-Length → 903
Content-Type   → text/html; charset=UTF-8
Date           → Sat, 14 May 2016 09:16:57 GMT
X-Powered-By   → Servlet/2.5 JSP/2.1

Can someone please suggest how to get PUT and POST operations to work?

如果为控制器方法指定了produces ，则还需要在请求上设置Accepts标头。
