##代码##回答by David Newcomb
You have the necessary jar file you need in hibernate-validator. This jar includes the javax.validation.ValidatorFactoryvalidation-api. So if you are including validation-api explicitly, you might have dependency conflicts. If not, you might just be having class reloading issues. Try cleaning your tomcat and restarting your IDE.
您在 hibernate-validator 中拥有所需的 jar 文件。这个 jar 包括javax.validation.ValidatorFactory验证 API。因此，如果您显式包含验证 API，则可能存在依赖项冲突。如果没有，您可能只是遇到类重新加载问题。尝试清理您的 tomcat 并重新启动您的 IDE。
回答by Amar Darekar
I had the same problem. For 2 months i was trying to find solution.
我有同样的问题。两个月来，我一直在努力寻找解决方案。
There was a error i made. I copied hibernate validator jar and pasted it in java installation directory.
我犯了一个错误。我复制了 hibernate 验证器 jar 并将其粘贴到 java 安装目录中。
Now i was using maven which also downloaded the validator jar.
现在我正在使用 maven，它也下载了验证器 jar。
There where two jars present and so the error arise. The problem was solved accidentally when i reinstalled java in my system.
那里有两个罐子，所以出现错误。当我在系统中重新安装 java 时，问题意外解决了。
