Question

我有一个工作的Errai GWT应用程序（GWT版本：2.5.1，Errai版本：3.0.0.Final），只是在gwt.xml中添加了Errai Validation（在POM中添加其依赖项之后）：

  <inherits name="org.hibernate.validator.HibernateValidator" />
  <inherits name="org.jboss.errai.validation.Validation" />

引发此错误：

Compile with -strict or with -logLevel set to TRACE or DEBUG to see all errors.
   [ERROR] Errors in '/tmp/gwt-codeserver-2599039351007089711.tmp/com.myapp.App/compile-1/gen/org/jboss/errai/validation/client/ValidatorFactoryImpl.java'

我认为你混合了“原生”GWT验证和Errai验证，而GWT验证仅适用于hibernate-validator-4.1.0。

使用Errai，您不必创建自己的ValidationFactory，只需@Inject a Validator。

使GWT验证工作
