问题描述
我在@Controller @RequestMapping方法中获得这样的参数:
@ModelAttribute(myCandidate)@Valid Candidate myCandidate,
BindingResult result
如何显式指定myCandidate的验证组?
解决方案
标准的java @Valid
注释不支持组。但是,Spring现在包括一个 @Validated
注释,它执行与 @Valid
相同的工作,但允许您指定
@ModelAttribute(myCandidate)@Validated(UpdateGroup.class)Candidate myCandidate
请注意,此注释仅适用于Spring 3.1及更高版本。
I get so parameters in @Controller @RequestMapping method:
@ModelAttribute("myCandidate") @Valid Candidate myCandidate,
BindingResult result
How can I explicit specify validation group for myCandidate ?
解决方案 The standard java @Valid
annotation doesn't support groups. However, Spring now includes an @Validated
annotation which does the same job as @Valid
, but allows you to specify which groups to use in the validation:
@ModelAttribute("myCandidate") @Validated(UpdateGroup.class) Candidate myCandidate
Note that this annotation is only available in Spring 3.1 and newer.
