The standard java @Validannotation doesn't support groups. However, Spring now includes an @Validatedannotation which does the same job as @Valid, but allows you to specify which groups to use in the validation:
标准的 java@Valid注释不支持组。但是，Spring 现在包含一个@Validated注释，它与 完成相同的工作@Valid，但允许您指定在验证中使用哪些组：
@ModelAttribute("myCandidate") @Validated(UpdateGroup.class) Candidate myCandidate
Note that this annotation is only available in Spring 3.1 and newer.
请注意，此注释仅在 Spring 3.1 及更新版本中可用。
