Validation 使用jbosserrai进行Bean验证

我想用Errai框架制作一个GWT应用程序，但在数据绑定和验证方面遇到了一些问题

我的pom.xml

<dependency>

  <groupId>org.jboss.errai</groupId>

  <artifactId>errai-validation</artifactId>

  <version>${errai.version}</version>

</dependency>

<dependency>

  <groupId>javax.validation</groupId>

  <artifactId>validation-api</artifactId>

  <scope>provided</scope>

</dependency>

<dependency>

  <groupId>javax.validation</groupId>

  <artifactId>validation-api</artifactId>

  <classifier>sources</classifier>

  <scope>provided</scope>

</dependency>

<dependency>

  <groupId>org.hibernate</groupId>

  <artifactId>hibernate-validator</artifactId>

  <version>4.2.0.Final</version>

  <scope>provided</scope>

</dependency>

<dependency>

  <groupId>org.hibernate</groupId>

  <artifactId>hibernate-validator</artifactId>

  <version>4.2.0.Final</version>

  <scope>provided</scope>

  <classifier>sources</classifier>

</dependency>

是否缺少另一个模块

我是正确的，Errai正在创建ValidationFactory并注入正确的实例？因此，我不必像下面这样创建自己的ValidationFactory：

---

是的，没错。您不必创建自己的ValidationFactory。我会帮你的。您可以简单地@注入一个验证器

我已经使用3.0.1.Final编写了一个版本的勘误表教程，该教程正好显示了这一点（按照中的说明）。我已把这个计划付诸实施

---

您粘贴的最后一个错误没有包含足够的信息，无法调查此操作失败的原因。但是，您应该在devmode控制台中看到更多错误信息。

勘误表验证是否适用于最新的GWT和勘误表，即2.7.0和3.1.1.Final？或者勘误表3.1.1.Final是否与GWT的2.7.0版本兼容？
