【原】Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

简介：以前我的个人博客中的入参校验都是用if来做的，效果有，但是不够优雅，这次升级的过程中，我也将它废掉了，直接引入了validator校验框架，这么简单的一个问题，竟然也报错了：“Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath”，找到问题原因之后，觉着挺有意思，特写此文记录下来，以便自己以后查阅，也方便他人碰到相同的问题时有可参考的资料。

这个问题出现的原因很简单，只要不是java新手，基本上一眼就可以看出，那就是没有引入hibernate-validator框架包导致的问题。

我为什么说它出现的很有意思呢？

正常来说，如果我没有引入jar包，是使用不了框架提供的注解的，但是我在使用@NotNull这些注解的时候，它却没有报错，这也导致我没有第一时间发现问题的原因所在，直到报错了之后，我又仔细检查了一下路径，发现并没有引入错，确实是javax.validation.constraints，我点进去看了一下，发现在import的时候，使用的是jdk自带的javaee-api包中的@NotNull注解，它的包路径和hibernate-validator的包路径一模一样。

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <!--这里必须是8.0，因为我使用的hibernate-validator是6.0.13.Final版本-->
    <version>8.0</version>
</dependency>

注意上面那行注释信息，具体原因请移步：java.lang.NoSuchMethodError: javax.validation.BootstrapConfiguration.getClockProviderClassName()Ljava/lang/String

好了，问题就是出在这里了，虽然jdk提供了一些列的注解，但是具体的校验逻辑，咱还是得依赖hibernate-validator呀！！！

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.13.Final</version>
</dependency>
