Validation GWT验证错误

我在GWT项目中添加了验证可能性。但它不起作用。每次尝试验证某些内容时，我都会遇到以下错误：

Rebinding com.val.client.SampleValidatorFactory.GwtValidator

Unexpected error trying to instantiate Generator 'com.google.gwt.validation.rebind.ValidatorGenerator'

请帮助我解决这个问题。

错误是什么？在开发模式下，您只会看到几行这样的内容，但单击任何一行都会提供更多详细信息。您可能会发现编译项目更容易，并在那里看到完整的错误。错误行是

尝试实例化Generator'com.google.gwt.validation.rebind.V时出现意外错误alidatorGenerator'

。前两行：

Rebinding com.val.client.SampleValidatorFactory.GwtValidator调用generator com.google.gwt.validation.rebind.ValidatorGenerator

来自调试器。是的，隐藏了错误信息：`java.lang.NoClassDefFoundError:javax/validation/ParameterNameProvider`。我起初没有看到它时间。请尝试跟踪该错误消息-如果没有帮助，请共享完整的错误日志，以及所有可用的错误。这可能有助于编译，以便您可以在一个日志中获取整个错误集。问题出在hibernate validator和validation api的兼容版本中。相同的问题已在此处查看。谢谢您，Colin，在rig中指导我ht方向。
