如何解决无法找到配置，因为找不到Bean验证提供程序-Vaadin 14 Spring Boot

我正在尝试将CRUD-add-on与Vaadin 14一起使用。但是当我尝试运行此视图时：

@Route("configuration")
@JsModule("./styles/shared-styles.js")
@CssImport("./styles/views/main/main-view.css")
public class ConfigurationView extends AppLayout {

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    public ConfigurationView(YoloObjectService yoloObjectService,ObjectNameService objectNameService) {
        
        System.out.println(yoloObjectService == null);
        System.out.println(objectNameService == null);
        // crud instance
        GridCrud<YoloObjectEntity> crud = new GridCrud<>(YoloObjectEntity.class);

        // grid configuration
        crud.getGrid().setColumns("email","active","objectName","threshold");
        crud.getGrid().setColumnReorderingAllowed(true);

        // form configuration
        crud.getCrudFormFactory().setUseBeanValidation(true);
        crud.getCrudFormFactory().setVisibleProperties("email","threshold","objectName");
        crud.getCrudFormFactory().setFieldProvider("objectName",new ComboBoxProvider<>("Object Name",objectNameService.findAll(),new TextRenderer<>(ObjectNameEntity::getName),ObjectNameEntity::getName));

        // layout configuration
        setContent(crud);
        crud.setFindAllOperationVisible(false);

        // logic configuration
        crud.setOperations(() -> yoloObjectService.findAll(),user -> yoloObjectService.save(user),user -> yoloObjectService.delete(user)
        );
    }
}

由于上述crud.getCrudFormFactory().setUseBeanValidation(true);，我收到此错误。

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

重现问题：

要重现该问题，请运行项目，然后转到http://localhost:8080，然后转到configuration选项卡，然后按+符号。现在，您将有两个关于Bean验证的错误。

问题：

如何找到该Bean验证程序？

解决方法

Jakarta Bean验证（以前是Java Bean验证）是一个API，您需要提供它的实现才能使用它。有两个，Hibernate Validator和Apache BVal。您可以将其中任何一个添加到您的pom.xml文件中。根据您的运行时环境，以不同的方式添加这些内容。既然您似乎正在使用Spring Boot，则可以添加以下依赖项：

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

我建议您阅读this tutorial，以快速更好地理解Jakarta Bean验证。这是一个非常流行的API，将来很有可能会在其他项目中找到它。

,

如tutorial中所述，您需要有一个实际的Jakarta Bean验证器实现类。在链接的教程中，根据您的环境，列出了可以使用的可用依赖项列表。我还是建议您阅读整个教程。

因此，如果您有Java EE环境，请将其添加到pom：

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.1.5.Final</version>  /* check for the latest version at https://hibernate.org/validator/documentation/getting-started/ */
</dependency>

如果您具有Spring Boot，请尝试以下操作：

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

对于Java SE，请尝试以下操作：

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.1.5.Final</version>  /* check for the latest version at https://hibernate.org/validator/documentation/getting-started/ */
</dependency>

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>jakarta.el</artifactId>
    <version>3.0.3</version>
</dependency>
