Spring Boot Rest API @RequestBody 中的@Valid 与@Validated [英] @Valid vs @Validated in Spring Boot Rest API @RequestBody

问题描述

我来自 .NET 开发 REST API 背景.现在使用 spring boot 处理 java REST 项目.

I am coming from a .NET background in developing REST APIs. Now working on java REST project using spring boot.

首先我在控制器@RequestBody 上的验证停止工作.在尝试修复它时，我看到了不同的实现方式.那么注释@RequestBody 的正确方法是什么?

First my validation at the controller @RequestBody just stop working. While trying to fix it, I saw different ways to implement. So what would be the correct way to annotate the @RequestBody?

@Validated @RequestBody

或

@Valid @RequestBody

推荐答案

两者一般没有太大区别，@Valid 来自 JSR-303 标准，@Validated 是弹簧标准.根据spring文档:

There are generally no huge difference between them two, @Valid is from JSR-303 standand, @Validated is spring standard. according to spring document:

Spring 提供了一个 Validator 接口，可用于在应用程序的所有层中进行验证.在 Spring MVC 中，您可以将其配置为全局 Validator 实例，在遇到 @Valid 或 @Validated 控制器方法参数时使用，和/或通过 @InitBinder 方法作为控制器内的本地验证器.可以组合全局和本地验证器实例以提供复合验证.

Spring provides a Validator interface that can be used for validation in all layers of an application. In Spring MVC you can configure it for use as a global Validator instance, to be used whenever an @Valid or @Validated controller method argument is encountered, and/or as a local Validator within a controller through an @InitBinder method. Global and local validator instances can be combined to provide composite validation.

参考:https://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-validation

但是有区别，其中之一是例如，如果您需要在验证注释中使用group，则需要使用@Validated，它不受支持使用 @Valid.

However there are differences, one of them is for example, if you need use group in your validation annotation, you need to use @Validated, it is not supported with @Valid.
