Question

我正在尝试使用hibernate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/google-web-toolkit/source/browse/trunk/samples/validation/

上的示例验证项目配置了我的项目

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>

验证在开发模式下在客户端和服务器端都很完美，但在尝试gwt编译时，我得到：

gwtc-production:

显然有一些我不见的源jar。我（和其他人）在我的类路径上：

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

我还尝试添加joda-time-2.1.jar，joda-time-2.1-sources.jar，jsoup-1.6.3.jar和jsoup-1.6.3-sources.jar。

不应该继承org.hibernate.validator.HibernateValidator来处理超级源代码所以我不需要提供源代码吗？谁能看到我错过的东西？

Answer 1

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

使用4.1.0-Final（或样本中可能为4.0.2.GA）而不是4.2.0。

可以在GWT Tracker中跟踪问题，我们应该至少明确记录不兼容性。

Answer 2

我不知道Hibernate验证的GWT实现。但是为什么GWT试图从你的Hibernate源jar中理解代码呢？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。

如果您同意我的意见，那么请不要在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。

Answer 3

4.1.0也为我工作，经过一段时间后我发现更高版本存在一些问题。因此，使用与gwt（http://www.gwtproject.org/doc/latest/DevGuideValidation.html）教程中推荐的版本相同的版本，我也有编译警告：

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

我修正了：

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

gwt编译期间的GWT验证错误 - 没有可用的源代码
