Question

最近，我决定使用JSR 303验证bean在我们的项目中，但是当我运行JUNI测试时，它出错了，日志如下：

有人告诉我这是由于JAR文件冲突造成的。但我不知道哪个JAR存在冲突。任何人都可以告诉我哪些JAR文件存在冲突。对我来说任何帮助都很大，谢谢！

Answer 1

没有JAR列表，在这里很难帮到你。你的项目中有maven吗？

如果是这样，你可以使用`mvn dependency：tree并查看jar树。

您可能正在使用不符合JPA 2.0规范的Hibernate规范ProviderUtil类是在JPA 2.0中引入的，因为doc说明： ProviderUtil

另一个问题是：您是独立运行还是在某个容器内运行（应用程序/ Web服务器或其他东西）例如，如果您正在运行JBoss，它在lib文件夹中有自己的jar，也可能与您的jar冲突。您是如何运行JUnit测试的？

Answer 2

我遇到了类似的问题。实际上，HibernatePersistence在实体jar中没有ProviderUtil（）方法。以下组合效果很好。

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>5.0.0.Final</version>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
 </dependency>

 <dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.5.Final</version>
</dependency>

如果它只是验证问题，请考虑使用自己的TraversableResolver实现，而不是JPATraversableResolver或DefaultTraversableResolver。 Here's how to do it

JPATraversableResolver可能会导致对JPA的不受欢迎的依赖。 Here's a guy with a similar problem.

当然，如果您希望您的应用程序符合JPA2标准，那么这不是解决方案。

public class MyTraversableResolver implements TraversableResolver {

     public boolean isReachable(Object traversableObject, Path.Node traversableProperty, Class rootBeanType, Path pathToTraversableObject, ElementType elementType) {
        return true;
     }

     public boolean isCascadable(Object traversableObject, Path.Node traversableProperty, Class rootBeanType, Path pathToTraversableObject, ElementType elementType) {
        return true;
     }
}

无法运行java验证（JSR 303）
