使用Vaadin Bean验证的Maven？

Question

我尝试使用Maven和Vaadin Bean验证来创建一个应用程序来验证我的bean，但现在对我没有用。

我正在尝试这个。

@Entity
public class Person{
    @Id
    @GeneratedValue
    private Integer id;

    @NotNull
    @NotEmpty
    @Size(min=5, max=50, message="insert first name")
    private String firstName;

    @NotNull
    @NotEmpty
    @Email
    private String email;

}

//my app
public class LoginView extends VerticalLayout{
     private TextField firstName, email;
     private BeanFieldGroup<Person> binder;
     private FormLayout form;

     public LoginView(){
         form = new FormLayout();
         binder = new BeanFieldGroup<Person>(Person.class);
         Field<?> field = null;

         field = binder.buildAndBind("Firstname", "firstName");
         firstName = (TextField)binder.getField("firstName");
         form.addComponent(firstName);

         field = binder.buildAndBind("Email", "email");
         email = (TextField)binder.getField("email");
         form.addComponent(email);

         this.addComponent(form);
     }
}

我添加了hibernate-validator作为依赖，但仍然无法正常工作。在vaadin bean验证器文档中说要使用Hibernate Validator或agimatec-validation。

我需要为此工作添加哪个依赖项？

方法isBeanValidationImplementationAvailable（）返回true，Debug低于。

11:26:54,112 DEBUG [org.hibernate.validator.internal.engine.resolver.DefaultTraversableResolver] - Found javax.persistence.Persistence on classpath containing 'getPersistenceUtil'. Assuming JPA 2 environment. Trying to instantiate JPA aware TraversableResolver
11:26:54,113 DEBUG [org.hibernate.validator.internal.engine.resolver.DefaultTraversableResolver] - Instantiated JPA aware TraversableResolver of type org.hibernate.validator.internal.engine.resolver.JPATraversableResolver.
11:26:54,113 DEBUG [org.hibernate.validator.internal.xml.ValidationXmlParser] - Trying to load META-INF/validation.xml for XML based Validator configuration.
11:26:54,113 DEBUG [org.hibernate.validator.internal.xml.ValidationXmlParser] - No META-INF/validation.xml found. Using annotation based configuration only.
Is bean validation implementation available: true

Answer 1

它应该在您致电binder.commit()时进行验证。检查类路径上是否有javax.validation.Validation类。

如果不是这样，请调试isBeanValidationImplementationAvailable()上的BeanFieldGroup静态方法并发布您发现的任何进一步详情。

Answer 2

您需要使用随Vaadin Bean Validation插件一起提供的BeanValidationForm和BeanValidationValidator。 您可以在svn为此插件找到一些演示代码。

Answer 3

我有同样的问题，决定是否包含在依赖项<artifactId>javaee-api</artifactId>

中
