我有一个 Spring Boot 应用程序，我正在创建 war 文件并在 Tomcat 8 上进行部署。代码在我的 Eclipse Oxygen 中运行时运行良好，并且在 Tomcat8 上运行应用程序时出现异常。

任何人都可以让我知道为什么我在运行 Tomcat 时会收到此错误。
spring-boot-starter-web 给 hibernate-validator 添加了一个依赖，因此 spring 需要配置一个验证器依赖。
删除该依赖项，添加排除项。我看到你评论了排除：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
</exclusion>
</exclusions>
</dependency>
或者如果你想使用这个依赖，那么升级到最新版本：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.13.Final</version>
</dependency>
