BeanValidation 错误 - 在类路径上找不到 JSR 303 Bean 验证实现

Question

我正在研究这个 Vaadin 教程系列。

https://www.youtube.com/watch?v=k-DxZ1reIdM&list=PLcRrh9hGNallPtT2VbUAsrWqvkQ-XE22h&index=11

文本版本：https : //vaadin.com/learn/tutorials/modern-web-apps-with-spring-boot-and-vaadin/vaadin-form-data-binding-and-validation？

我正在尝试使用绑定，但在我的终端中出现以下错误：

2020-11-22 09:11:11.012  INFO 38103 --- [nio-8080-exec-2] c.vaadin.flow.spring.SpringInstantiator  : The number of beans implementing 'I18NProvider' is 0. Cannot use Spring beans for I18N, falling back to the default behavior
2020-11-22 09:11:11.373  INFO 38103 --- [nio-8080-exec-2] com.vaadin.validator.BeanValidator       : A JSR-303 bean validation implementation not found on the classpath or could not be initialized. BeanValidator cannot be used.

更多在下：

Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

如何添加Bean 验证提供程序？我正在使用 vaadin 作为与教程中相同的 Maven 项目。

Answer 1

通过添加以下依赖项解决

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>
