如何做Bean驗證

這是我的豆validation.but情況下的代碼示例是形式提交的錯誤信息沒有顯示如何做Bean驗證

//controller class 
     @RequestMapping(value= "/offer.create", method=RequestMethod.POST) 
     public String doActions(@Valid @ModelAttribute ("offers") Offer offer, BindingResult result, 
       @RequestParam String action, Map<String, Object> map, 
       HttpServletRequest request){ 

     // 

      if(result.hasErrors()) { 
       /*map.put("offers", offerservice.getAlloffers()); 
       map.put("Offer", new Offer()); 
       map.put("SeasonTypes", new SeasonTypes()); 
       map.put("timeBased", new TimeBased()); 
       map.put("seasons", offerservice.getAllSeasons());*/ 
       System.out.println("inside the error section!!"); 
    //   System.out.println(merchantService.getAllMerchant().size()); 
       System.out.println("The error "+result); 

       return "create-offer"; 



      }

// ------------ -------------------------------------------------- -------------- 這是JSP形式

               </form:form> 
         </div> 
         </div>

這是模型類

public class Offer implements java.io.Serializable { 

    private long offerid; 
    private Merchant merchant; 
    private MerchantUser merchantUserByAddedByRef; 
    private MerchantUser merchantUserByLastModifiedByRef; 
    private String issueDateTime; 
    private BigDecimal pointsAllocated; 
    private String expiryDate; 
    private String offerHeading; 
    @NotEmpty 
    private String offerSubheading; 
    @NotEmpty 
    private String offerDescription; 
    private String offerFilterTypes; 
    private String videoUrl;

這是message.property文件

NotEmpty.Offer.offerSubheading = Heading field can't be Empty! 
NotEmpty.Offer.offerDescription = Heading field can't be Empty!

在這裏jsp頁面，點擊後按鈕將在進行驗證後會出現相關form.when，如果他們有一些錯誤重定向到jsp頁面然後不應該有這種形式的形式here.because後，才按一下按鈕。所以這個錯誤味精不能顯示

以下圖片看來，.JSP視圖.jsp page view before press single image button after click that single image button

對不起 - 有問題嗎？ –

是的。我需要重定向表單。但是在發生驗證錯誤後，此處不會重定向該表單。上面的鏈接顯示的jsp頁面我需要重定向圖像顯示在第二鏈接[2]不是[1] [1] jsp頁面視圖之前按下單個圖像按鈕[2]後單擊該單個圖像按鈕 – kaushi

終於我做我的工作問題是@ModelAttribute（「offers」）---> offers and commandName =「Of fer「彼此不匹配 :)
