如何做Bean验证

这是我的豆validation.but情况下的代码示例是形式提交的错误信息没有显示如何做Bean验证

//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"; 



      }

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

这是模型类

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;

这是message.property文件

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

在这里jsp页面，点击后按钮将在进行验证后会出现相关form.when，如果他们有一些错误重定向到jsp页面然后不应该有这种形式的形式here.because后，才按一下按钮。所以这个错误味精不能显示

以下图片看来，.JSP视图.jsp page view before press single image button after click that single image button

对不起 - 有问题吗？ –

是的。我需要重定向表单。但是在发生验证错误后，此处不会重定向该表单。上面的链接显示的jsp页面我需要重定向图像显示在第二链接[2]不是[1] [1] jsp页面视图之前按下单个图像按钮[2]后单击该单个图像按钮 – kaushi

终于我做我的工作问题是@ModelAttribute（ “offers”）---> offers and commandName =“Of fer“彼此不匹配 :)
