Bean验证组序列不工作

Question

我希望先用groups指定的注释。class一起激发，然后再进行second.class验证。我不明白为什么用组指定的验证没有被激发。

有人能给我指路吗。

@GroupSequence({MyForm.class, OrderedChecks.class})
public class MyForm {

  @NotBlank
  @Size(min = 2, max = 40)
  @Pattern(regexp = "^[\\p{Alnum} ]+$", groups = First.class)
  @UniqueName(groups = Second.class)//Custom validation
  private String name;

  @NotBlank
  @Size(min = 2, max = 40)
  private String url;

  @NotBlank
  @Size(max = 100)
  private String imagePath;

  //Custom Validation
  @CheckContent(acceptedType = <someString>, allowedSize=<someval>, dimensions=<someval> groups = Second.class)
  private MultipartFile image

...
}

@GroupSequence(value = {Default.class, First.class, Second.class})
public interface OrderedChecks {}

@Controller
@RequestMapping(value = "/myForm")
public class MyFormController {

    @RequestMapping(method = POST)
    public String completeSignUp(@Valid @ModelAttribute("myForm") final MyForm myForm,
                            BindingResult result, RedirectAttributes redirectAttributes, Model model) {

        if(result.hasErrors()) {
            model.addAttribute(companyDetailsForm);
            //ERROR_VIEW="myForm";
            return ERROR_VIEW;
        }
       // Doing something else.
      return <success view>;
   }
}

使用Spring的@validated而不是@valided。这将允许您指定组并控制序列。

将控制器方法更改为：

@RequestMapping(method = POST)
public String completeSignUp(@Validated(OrderedChecks.class) @ModelAttribute("myForm") final MyForm myForm,
                        BindingResult result, RedirectAttributes redirectAttributes, Model model) {
...
}

注意，在MyFormbean之上不需要@groupsequence（{myform.class,orderedchecks.class}）。
