我试图通过Tomcat在本地计算机上运行Spring MVC应用程序，但我看到：

NoClassDefFoundError: javax/validation/ValidatorFactory

我在webapp的lib文件夹中有validation-api-1.0.0.GA.jar。我正在使用Tomcat 7。如有任何指导，将不胜感激。

您已经在hibernate-validator中拥有了所需的jar文件。此jar包含javax.validation.ValidatorFactory validation-api。因此，如果您显式包含validation-api，则可能会出现依赖关系冲突。如果没有，则可能只是出现了类重新加载问题。请尝试清理tomcat并重新启动IDE。

添加到pom.xml

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

😤 我在第一次启动测试时遇到了这个问题。
该问题是由于test dependency与validation dependency之间得不兼容造成得.
📝我的pom.xml：

<dependency>
   <groupId>jakarta.validation</groupId>
   <artifactId>jakarta.validation-api</artifactId>
   <version>3.0.2</version>
</dependency>

😀 我解决了这个问题，我把jakarta.validation-api换成了spring-boot-starter-validation。
📝我的pom.xml：

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

我也遇到了同样的问题，两个月来我一直在努力寻找解决办法。
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。
现在我使用的是Maven，它也下载了验证器jar。
在那里有两个jar，所以错误出现了。当我在我的系统中重新安装java时，这个问题意外地解决了。

对我来说，这是一个冲突与雅加达。验证版本3.0.1。回滚到2.0.2修复它。

在项目jar文件中包含jakarta.validation-api，这将强制Tomcat使用它。在pom.xml中添加如下提供的作用域：

<dependency>
    <groupId>jakarta.validation</groupId>
    <artifactId>jakarta.validation-api</artifactId>
    <version>3.0.2</version>
    <scope>provided</scope>    
</dependency>

祝你好运。
