就我而言，我添加了以下依赖项并且它起作用了，即使我不需要任何验证，也可能是 Java 更新导致了这个问题.

In my case, I added the following dependency and its worked, Even I do not need any validation, maybe the Java update caused this issue.

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