錯誤415 - 同春不支持的媒體類型4

Question

我從第3版（基於XML）升級春季4.2.4（基於註解的）

控制器

@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()); 
     } 
    } 
} 

Spring-Servlet.xml

在我的類路徑JAR文件 -

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 

我能夠執行GET操作，其成功返回JSON值，但PUT和POST操作不起作用。我使用Postman作爲REST客戶端。我也試過路過的URL PUT操作的標頭值Content-Type設置爲aplication/json後，但它總是返回

錯誤415 - 不支持的媒體類型。

我收到以下響應頭：

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 

可有人請建議如何獲得PUT和POST運營工作？

如果您爲控制器方法指定produces，則還需要在請求上設置Accepts標頭。
