我想用 Errai 框架制作一个 GWT 应用程序,但我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>
我的 app.gwt.xml 包括 Errai-Validation 和 HibernateValidator 模块:
<inherits name="org.jboss.errai.validation.Validation" />
<inherits name="org.hibernate.validator.HibernateValidator" />
没有未解决的依赖项我已经仔细检查过。
当我尝试使用 mvn gwt:run 运行应用程序时,出现以下错误:
java.util.concurrent.ExecutionException: org.jboss.errai.ioc.rebind.ioc.exception.UnsatisfiedDependenciesException: @> org.jboss.errai.ui.nav.client.local.Navigation

这就是 Bootstrap 失败并且应用程序抛出 onModuleLoad 异常并且没有启动的原因。
如果我删除 2 个验证模块,我就可以启动应用程序而不会出现任何错误。
我正在使用 3.0.1 FINAL 版的 Errai 教程。
谢谢你的帮助 :)
编辑:
我通过添加解决了错误
<inherits name="org.jboss.errai.ui.nav.Navigation" />
到我的 app.gwt.xml 但现在我遇到了这个异常的下一个问题:

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?所以我不必像这里一样创建自己的 ValidationFactory:
