Vaadin 7 - Bean验证

Question

我一直在尝试Vaadin 7.首先,我必须管理我在Vaadin安静的一个菜鸟并且对JAVA持久性不太熟悉.因此,我正在尝试学习bean验证以及如何使用它.我已经按照几个教程,但很难确定哪个是Vaadin 7的最新和正确的.尽管如此,我尝试下载并使用JPA容器和BeanValidator,我无法让它工作.这是我正在使用的代码:

package com.example.firstvaadin;

import java.io.Serializable;

import org.hibernate.validator.constraints.Email;
import javax.validation.constraints.*;

public class RegisterBean implements Serializable{

    public  RegisterBean(String email){
        this.email = email;
    }

    @Size(min = 5, max = 50)
    private String email;

    public void setEmail(String email) {
        this.email = email;
    }

    public String getEmail() {
        return email;
    }
}

和

RegisterBean rbean = new RegisterBean("");
BeanItem<RegisterBean> item = new BeanItem<RegisterBean>(rbean);
TextField email = new TextField("email",item.getItemProperty("email"));
email.setImmediate(true);
layout.addComponent(email);
email.setNullRepresentation("");

但是我在下面的代码中遇到了运行时异常:email.addValidator(new BeanValidator(RegisterBean.class,"email"));

The exception is:

我不知道缺少哪些类,我添加了hibernate jar和validation-api.jar

有人可以帮我一把吗？

此外,这是一个jar文件列表,它位于/ WebContent/WEB-INF/lib目录中,并在Eclipse中作为类路径添加.

classmate-0.8.0.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
hibernate-search-engine-4.3.0.Alpha1.jar
hibernate-search-orm-4.3.0.Alpha1.jar

vaadin-sqlcontainer-1.1.0.jar
validation-api-1.0.0.GA.jar
validation-api-1.1.0.Final.jar

classnotfound异常消失但现在又有一个新异常:

我敢肯定你已经解决了你的问题,但是对于其他人来说这么晚(我是)并且还使用Vaadin 7 Framework,Vaadin Bean Validator与Vaadin 7不兼容,只有下载时提到的Vaadin 6这里的页面:

https://vaadin.com/directory#addon/vaadin-bean-validation

即使在他们自己的演示(jpacontainer-addressbook-demo)中,他们也使用pom.xml中的hibernate-validator:

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>4.2.0.Final</version>
    </dependency>

希望这能帮助别人,因为它有我.
