我曾试图使用装饰,但我最后站有以下错误:

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.

更不用说:

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

我如何增加Bean Validation提供商? I ́m与Movaadin合作,作为教学项目。

Answer 1

Solved by adding the following dependency

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

Answer 2

Hibernate Validator

添加整个<条码>代谢-启动-效力>。

You can simply add the Hibernate Validator, which will add the minimum amount of libraries to your project.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>yourHibernateVersion</version>
</dependency>

这种办法由Vadin公司本身提出,因为你可参看here。

Hibernate Validator serves as the only implementation of Jakarta Validation (formerly known as Bean Validation) specification versions 2.0, 3.0, and upcoming 3.1.
