ValidationException: Unable to find a default provider
提问by Thom
I found three entries for this in stack overflow:
我在堆栈溢出中找到了三个条目：
javax.validation.ValidationException: Unable to find default provider
javax.validation.ValidationException：无法找到默认提供程序
javax.validation.ValidationException: Unable to find a default provider
javax.validation.ValidationException：无法找到默认提供程序
Spring MVC 3 Validation - Unable to find a default provider
and all three say to add hibernate validator to the class path. What do I do when I've done that and still get the same error?
并且所有三个都说将休眠验证器添加到类路径中。如果我已经这样做了，但仍然出现同样的错误，我该怎么办？

The Spring Forum helped me out. http://forum.springsource.org/showthread.php?124477-ValidationException-Unable-to-find-a-default-provider
Something to do with hibernate 3.6.x. I downgraded to Hibernate 3.5.6-Final and it works like a charm.
与 hibernate 3.6.x 有关。我降级到 Hibernate 3.5.6-Final，它就像一个魅力。
Thanks for all of the help.
感谢所有的帮助。

Add hibernate-validator dependency which has implementation of JSR 303 (bean validation).
添加具有 JSR 303（bean 验证）实现的 hibernate-validator 依赖项。
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>

Maybe it would be helpful to know that ZIP archive downloaded from provider site should be extracted upfront adding it as dependency to your project. For example I try to add archive hibernate-validator-4.3.2.Final-dist.zip to my project dependencies in IDE but it doesn't work. Then I extract it and add all the libraries from dist folder to my project and issue disappear.
知道从提供者站点下载的 ZIP 存档应该预先提取，将其作为依赖项添加到您的项目中，这可能会有所帮助。例如，我尝试在 IDE 中将存档 hibernate-validator-4.3.2.Final-dist.zip 添加到我的项目依赖项中，但它不起作用。然后我提取它并将 dist 文件夹中的所有库添加到我的项目中，问题消失了。
