You're looking for javax.validation:validation-api .您正在寻找javax.validation:validation-api 。

Also, as Amir mentioned, if you've found stackoverflow useful, accept some answers.另外，正如 Amir 提到的，如果您发现 stackoverflow 很有用，请接受一些答案。 People will be more inclined to help out.人们会更愿意帮忙。

If you are using maven, just add the external dependency in your pom.xml如果您使用的是 maven，只需在 pom.xml 中添加外部依赖项

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

Verify the latest version here: https://mvnrepository.com/artifact/javax.validation/validation-api在此处验证最新版本： https : //mvnrepository.com/artifact/javax.validation/validation-api
