我正在尝试使用休眠验证器进行 gwt 验证。我已按照 http://code.google.com/p/google-web-toolkit/wiki/BeanValidation 中的步骤操作，并根据http://code.google.com/p/上的示例验证项目配置了我的项目google-web-toolkit/source/browse/trunk/samples/validation/

我的 .gwt.xml 文件包含：

<inherits name="org.hibernate.validator.HibernateValidator" />

和我的自定义验证工厂：

<replace-with class="my.package.here.client.validation.ValidatorFactory">
<when-type-is class="javax.validation.ValidatorFactory" />
</replace-with>

在开发模式下，验证在客户端和服务器端都可以完美运行，但是在尝试 gwt 编译时，我得到：

gwtc-production:

显然我缺少一些源 jar。我的类路径中有（除其他外）：

hibernate-validator-4.2.0.Final.jar
hibernate-validator-4.2.0.Final-sources.jar

我也尝试添加joda-time-2.1.jar,joda-time-2.1-sources.jar和.jsoup-1.6.3.jarjsoup-1.6.3-sources.jar

不应该继承 org.hibernate.validator.HibernateValidator 照顾超级来源，所以我不需要提供来源？谁能看到我错过了什么？

GWT 是针对 Hibernate Validator 4.1.0-Final 构建的，并且依赖于它的一些内部结构（PathImpl, NodeImpl），显然这些在 Hibernate Validator 4.2.0 中已经发生了变化。

使用 4.1.0-Final（或者可能是示例中的 4.0.2.GA）而不是 4.2.0。

可以在GWT Tracker中跟踪问题，我们可能至少应该明确记录不兼容性。

我不知道 Hibernate 验证的 GWT 实现。但是为什么 GWT 试图从您的 Hibernate 源 jar 中理解代码？如果它是 GWT 自己的代码，它应该来自它的 gwt-user.jar 或类似的东西。

如果你同意我的观点，那么不要在 GWT 编译类路径中包含任何真正的 Hibernate jar。无论如何，它不需要它/知道它。

4.1.0 也对我有用，一段时间后我发现更高版本存在一些问题。因此，使用与 gwt 教程中推荐的相同版本（http://www.gwtproject.org/doc/latest/DevGuideValidation.html）我也有一个编译警告：

detected warnings related to 'javax.validation.constraint'. is validation- version .jar on the classpath

我修复了：

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <scope>compile</scope>
</dependency>
