java - 让 GWT 验证发挥作用

Question

我有一个正在运行的 Errai GWT 应用程序(GWT 版本:2.5.1，Errai 版本:3.0.0.Final)，只需在 gwt.xml 中添加 Errai 验证(在 POM 中添加其依赖项之后):

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

抛出此错误:

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'

我认为您混合了“ native ”GWT 验证和 Errai 验证，并且 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 一个 validator 即可。
